  Hi, my Hp Pavilion is only 2 years and 2 months (not very old at all) but suddenly it does not start in Windows, it hangs at the HP logo screen, it starts with an HP logo screen then goes to another screen of the HP logo, and then freezes.

  I did a hard reset, still frozen.

  I removed the cover, he went out and placed him in, still nothing.

  There is no restore point.

  I ran chkdsk via the command prompt and had no error.

• Win 7 Pro X 64; system does not recognize my Sata HDD Ext USB Powered clos

  In the recent past, my system no longer recognizes my Powered Sata USB HDD Ext I closed deleted the April May security updates and nothing does not. Two updates would not uninstall: KB3020369 & KB3020370. They were both installed on May 7, just about the time the ext drive was not recognized.

  Thinking that the box Sata or HARD drive was unusable, I bought two new nothing helps. I think the above updates are the culprits. All the other external USB work correctly - key USB & USB powered drives Ext. I tried all the mentioned community wrapper work without result. Need help from MS on how to uninstall the updates above? The only thing I can think of to test my Win 7 should save all the files and images to all readers on an ext HDD and do a clean install without security updates. And then install updates one at a time security test activity USB I'm going. Also, I see other people having the same

  problems.

  FIX

  Problem solved. In my case, the external hard drive was plugged in and powered and the external drive appeared in 'surely remove the material and the media', but does not appear in Windows Explorer. It was enough of a drive letter. Left click on start, Control Panel, administrative tools, COMPUTER MANAGEMENT, storage, MANAGEMENT OF DISKS.  A list of drives has been shown. Mine has no drive letter. I have a click right and select the simple volume on the dark line, and followed the instructions.

  Everything is normal and I already copied the files on it. Thank you all for your efforts and help.

• Upgrade CPU, system does not boot, winload.exe "Windows cannot verify the digital signature for this file.

  Subject pretty much said it all.  I got a new CPU, shut down the computer, installed, and now Win7 does not start.  It hangs on a black screen gripe on a signature file.  Here is the full text:

  "A recent hardware or software change might be installed a file that is signed incorrectly or damaged, or maybe it's a malicious software from an unknown source."

  If you have a Windows installation disc, insert the disc and restart your computer.  Click 'Repair your computer' and choose a recovery tool.

  Otherwise, to start Windows, so you can investigate further, press the ENTER key to display the boot menu, press F8 for Advanced Boot Options, select last known good configuration.  If you understand why the digital signature file cannot be verified and want to start Windows without this file, temporarily disable driver signature enforcement.

  File: \Windows\system32\winload.exe

  Status: 0xc0000428

  Info: Windows cannot verify the digital signature for this file. »

  Well, the first thing I did was put in the installation CD and reboot to try the thing "repair your computer".  Charge, said he found a problem, said he has fixed the problem and restarted.  But it always hangs on the same screen of the error.

  So I tried to hit Enter and then F8 as it said to do, but brings me right to the error screen.  I'm stuck, there is nothing that I can do, and I need this computer to work tomorrow.

  Another interesting note is that the recovery on the installation CD tool identifies my system installed Windows Vista... wtf.

  Help?

  I don't know if this post will solve your problem, but it can give you new ideas or angles to try.

• System does not boot, get the white screen after preparation for auto repair

  Hello

  I have a Toshiba Satellite with Windows 8 and yesterday there were some ongoing update and must restart.  When the computer reboots, it took some time and then I got a blue screen (very quickly) who said something as she encountered a problem and needs to fix (it is really fast and I can't see the whole text).  Then goes and comes back as it is booting (with the toshiba logo) and he says prepare auto repair.  Then it goes to a white screen. I tried to get into the HARD drive recovery (power with F12) and when I select HDD Recovery and confirm Yes, it just goes to a blank screen.  I went into the Setup utility (powering now F2 while) and has chosen default install and who does not either (although it has fixed the problem with my keyboard backlight does not). Support of Toshiba said that it is the operating system, not the hard drive.  But I need a drive recovery media that will scan all.  Anyone know other options?  I have a disc of recovery of a Microsoft coming 8 Pro (dell).  Would it be an option, to use it (I got it on a flash drive) and start-up of that?  Thanks for the help.

  Hi John,.

  Thank you for the update.

  Given that you want to use the Windows 8.1 recovery disk, you won't perhaps able to start Windows 8 using Windows 8.1 because the computer may not be able to find the files of Windows 8 start to recover.

  Yes, you pouvez install 8.1 Windows using the recovery disk. However, you may not be able to perform the upgrade option when installing Windows 8.1. When you click install now and follow the instructions, you must choose the Custom Advanced option to continue installation. Choose Advanced custom options will create a folder in the C: drive (or any other partition when you do not want to install) named the Windows.old folder which expected to have all of your files and documents of previous installation and are accessible.

  Make sure you have the drivers available for the devices installed on the computer as network card, drivers etc. of video card you install Windows 8.1.

  Hope the information is useful. Please feel free to answer in the case where you are facing in the future other problems with Windows.

  Thank you.

• System does not boot after CHKDSK

  Reference Dell 745, XP SP3, fully patched. Had not run CHKDSK in 5 years, machine has been in use, thought it might be a good idea. NOT!

  I plan to CHKDSK/F, he ran at the next startup, then I get the splash screen, then black screen, nothing else. If I turn the power off, the next time you start trying to run CHKDSK again, and if I run it or not, same result - start screen, then nothing. What to do next?

  The machine is in reverse now - here's "the rest of the story" - pressing F8 didn't work, couldn't get into safe mode. Recovery Console is not installed on versions of our company. I was able to get a couple of our Support service for Office XP installation diskettes - only one is bootable and even through, that's for XP SP1 and I have XP SP3, it worked.

  Choose the option to repair install didn't solve the problem at all. Once again starting on the CD, I chose the Recovery Console. At this time, I chose FixBoot and FixMBR. And then when I removed the CD and booted up again, pressing F8 gave me access to the boot with Safe Mode and other options menu. Safe mode does not work - I got nowhere (I don't remember exactly what happened at this point, but it did not help). Which does not finally was the last good Configuration. Once I chose that and rebooted, I had a relatively normal cases, slow start and connection, without the detour by CHKDSK. He has been sluggish about 10 minutes longer than normal, but worked normally since.

  I don't see any reference to CHKDSK saves in my shaft system of the observer of events tools - any suggestions on where I could display them?

  My lesson learned here - if the system is not broken, CHDSK is going to break, so on modern systems, only run CHDSK when you experience the symptoms that you can't otherwise explain. That had been the case at home on a Win7 laptop, which had suddenly slow, with a blurry view near the start icon.  I had been worried about the virus and horses of Trojan, but a suggestion in the forum Win7 on Tek-Tips pushed me to run CHKDSK, who did to solve this problem. It's a relief to be back to normal!

• 5.1 surround Sound speaker system does not work in Windows 7 Professional 64-bit edition

  My problem is about the same as other users who cannot get their surround sound speaker system to work properly in Windows 7.

  I have a subwoofer and 5 speakers (2 front, 2 rear, 1 for the centre).  Connection to the RealTek HD Audio embedded is simple, orange for the subwoofer, green for the front and black for the rear.

  Test the sound in Control Panel-> windows sound produces a sound on all channels and RealTek HD Audio Manager at the same time, which is the desired configuration.

  However, different applications use different channels.  IE and Firefox use the front channels, VLC/MediaPlayer uses the back.  3D games (that is to say WoW) through all channels.  In each case the subwoofer does not work.

  I tried to download the latest drivers on the motherboard (Gigabyte) manufacturers site.  I even tried the supplied RealTek drivers (even if on the Web from RealTek site which is NOT recommended).  I tried to connect the connectors of the subwoofer to the different takes (reversed black and green).

  I have experimented with the settings in RealTek HD Audio Manager and control panel-> windows Sound.  Nothing works.

  These exact same subwoofer and speakers worked perfectly well on Windows XP.

  I have 2 questions:

  one) has anyone resolved their 5.1 & Windows 7 problem something that I have not yet tried?

  (b) when will Microsoft take this issue seriously?  All Microsoft provided answers just repeat what everyone

  has already tried.

  First disconnect the cable 3 (orange, green and black) then click on Control Panel configuration-hardware and sound - Real tek HD audio manager - central tick, subwoofer and rear pair, front left and right and filling of speaker

  Then click on advance device settings.

  Select "perform front and reading of output devices back two different audio streams simultaneously" and give ok

  Plug all three pins one by one and select the appropriate option in the popup windows.

  That's all.

  You give enough information for me to get this working.   My system runs Win 7 X 64 Home Premium.   When I select 5.1 sound capacity side my 550 x Logitech speakers are not recognized.  If I select 7.1, which is the capacity of my chip Realtek chipset, I can get the two outside are activated as a "rear" speakers and can push the test tones to each of the four surrounding speakers and the combination of Center/bass via the Realtek driver.

  Regarding the "front and reading of output devices back two different audio streams at the same time" worries... I can't find this option.  There are at least two suppliers of 'control of the interfaces' assets on my system.  One is provided by RealTek, the other by Microsoft.  The access roads to these interfaces is roundabout and confusing, to say the least.

  Some compromises are in order in my humble OPINION.  I have my Pandora one stream play in an acceptable way in my small study.  Many of the source of sounds streamed to me are recorded in stereo or mono, I find myself hitting the 'matrix' on my Logitech X 550 button quite frequently.  Sometimes a more recent piece is delivered which actually looks Ok without the decoder "matrix".

  What I would really like to be able to do is to "reconfigure on the fly" between the built in speakers on my Acer Z3731 system USB bar ' All in One ' and my external Logitech X 550 popular with the ability for the presentation of "5.1 surround sound" through three sons.  When I try your procedure, I don't get separate recognition of each thread, as it is trendy and often end up with its 2.1 being eliminated in my 5.1 speakers, because somehow Microsoft has re-recognized the built-in USB port based his bar instead of the three rear wires plugged into the outlets provided by the manufacturer of the system.

  If there was ever separate 'Speakers' and 'Realtek' icons in the UI on my system, speakers are long gone and I can't get back them.  All I see is the Realtek driver.  I would like to see the two icons 'Speakers' different, I could mark "integrated 2.1" and "5.1 external '", in addition to the driver Realtek.»  How can I get these to reappear?

  Can anyone suggest a way to have two different sets of "speakers" recognized and identified in the Microsoft UI in addition to the Realtek driver?  If I could get because of this, I think that the driver would let me 'set as default' one or the other speaker set, and I 'software switching' capable of letting me choose the external speakers or integrated sound bar offers the sound.

• Satellite Pro A200 - system does not boot

  Hello

  wondering if someone could help?
  My Satellite Pro A200 with windows XP does not start. It starts with the Toshiba screen.
  Then goes to a screen black with text where it says "PXEE61 media test failure - check cable" (I have no cable) then said out of PXErom; moves to the next screen, which lists the options: safe mode; safe mode with networking; safe mode with prompt local; Last Configeration well-known; Start windows normally.

  Which have been tried and results in loading from page turns on for about 20 seconds, then just to abandon and trying all the whole process again (before flashing a blue screen) Windows.

  Nothing seems to work - tried to take the battery on a... number oftimes and the power cable, but nothing helps.
  It's already happened, but after a few false starts gets going - but this time he just don't come out it. I could not take others where locally, but I would prefer not to because I live in Spain and need the laptop as soon as possible and do not know, I want to leave it in some otherwise are hands to the risk of wipe them the hard drive.

  So, I would be very grateful for any help as soon as possible and I fear tech short hand maybe having to explain.

  Thanks a lot, a lot.

  Hello

  I think the problem is that the operating system is not found on the HARD drive.

  The test failure PXEE61 media - check the cable appears especially if the laptop tries to boot from LAN.

  Why the laptop is trying to boot from the local network?

  Well,.

  -option may be the LAN was chosen first in the boot order in the BIOS
  -Maybe the drive is defective and so the laptop is trying to boot from LAN
  -the MBR (master boot record) is may be defective

  I think you should take the Toshiba Recovery CD and need to format the HARD drive and needs to be reinstalled the operating system.
  This should help.

  If not, then the HARD drive could malfunction and should be replaced!

• Installing the graphics card... System does not boot

  Hello

  I received a HP P6-2387ea today (I5, 8 gb, H61 Chipset) with the intention to introduce a new GeForce660 inside that also happened today.

  The PC boots up well with its default material and very well with my addition of a 500 watt PSU... However, when I add in the GeForce 660 does not start, I am rather greeted by 6 beeps to the bios, which is obviously not a good thing.

  My first thought was gpu at fault, but I tested it on another machine and it works fine. I also took a GeForce 460 of this old machine and tried in the new HP one, same result.

  I'm missing something here, or I have a faulty card or something?

  (To avoid responses of stupidity, yes the 500w PSU is a lot and the appropriate pci-e 6pins were attached).

  Any help would be appreciated.

  Hello

  First response to your title question is "no, your motherboard is not broken.

  Try this:

  Boot into the bios and go to the Secure --> Secure Boot Configuration topics. Now disable secure boot and turn on legacy mode. Now let's see if the PC will start using the material existing HP before you make any changes. If the PC starts, then try just a video card.

  View your results.  I have a suspicion about what the issue is for the motherboards that are active UEFI.

  --------------------------------------------

  Side note:

  It seems someone is trying to find an answer to this question using different HP computers as a way to find the answer when the PC is delivered W8 and active UEFI.

• HP ProBook s 4540 - system does not boot after recovery

  My friend gave me the laptop, because the system has not been detected. I decided to recovery operating system.
  I had to face following error messages:

  -I did not receive "Boot Device not Found" error

  I started the HARD drive with result success test

  -next step was to recovery OS
  He finished with the new error message
  "The boot image selected is not authenticated to. "Press to continue.
  According to this topic:
  http://h30434.www3.HP.com/T5/notebook-operating-systems-and-software/selected-boot-image-did-not-aut...
  I did following:
  -secureboot changed to disabled
  problem persisted

  -legacy changed to enabled
  Since then, I'm not able to do anything. When I leave the start system, it ends with the HP logo, and nothing happens.
  When I press ESC after a reboot, menu appears, but I am not able to enter the BIOS. If freezes all the time in the menu with the text highlihted.

  I tried to remove the battery, unplug the power, press the powerbutton for 30 seconds, nothing has changed.

  Next step should probably be to temporarily remove the RTC battery, but I don't know if I'm allowed to open it without losing the warranty.

  The laptop is about 3 months old.

  Hello:

  Because the laptop is under warranty, I suggest your friend contact HP technical support and ask them to solve the problem.

  When you get a not found boot device error it's hard drive (if the test says it is spent or not) or the drive controller on the motherboard.

  I wouldn't touch with a ten foot pole.

  HP support will probably have your friend go through certain stages that you did before they tell him what to do next as return them for warranty repairs, etc.

• System does not boot: failure of the video card or viruses? I do not know...

  Here's the deal: on a computer running Windows XP Pro SP3. Athlon, dual-core processor (2.4 gHz); 4 GB of memory; NVidia GeForce 7300 video card; and a Western Digital SATA, I met a failure while watching a DVD (using Media Player 11) and now I can't start.

  I have been having problems for a few days with my Dell flat screen monitor "energy saving" mode because it has detected no signal. After playing with this and obliging to recognize a digital signal rather than the automatic detection, all seemed well.

  During the film, the picture froze, the sound became a loud, grating buzz and shut down the system.  It has restarted as usual, but then would not start the rest of the way, stopping at the Windows XP screen.  The progress bar froze and spinning to stop the drive.

  However... on occasion, for example when the system remained some time, I can sometimes start in safe mode (but still, it hangs when starting "mup.sys") or he will move to the XP logon screen and freeze it.  I replaced the mouse and keyboard (whiched USB connections) used with their equivalents of PS/2, but nothing has changed.

  When I try to start, I hear all the clicks Associates, snoring and whatever else as if the startup continues normally.  However, when it stops, I can't "see" it on my network.

  I have a hunch that it is a damaged video card because also the failure during the film and previous issues of monitor, when I hit the map to try to reinstall, he felt much warmer that it should have, but a video card failure would prevent initialize to top?

  Any ideas?  I'm all that.

  It does for me, but of course as I said in my previous notice of Disclaimer: I want to emphasize that you should not take what I wrote as a definitive diagnosis. I can't see or test your computer from here. I give you my opinion on your computer based on my experience as a computer tech and what you have written.

  I understand that.  I was looking for another opinion by giving an update.

  However, it certainly seems that the jury went.  It freezes even trying to boot in the BIOS setup.  Thanks for the directions.

• Computer turns on but does not boot to Windows, startup repair does not work

  When I turn on my laptop, it brings me to a screen titled "Windows Error Recovery" which means the following:

  "Windows did not start.  A recent hardware or software change might be the cause. »

  He asks me if I want to '(recommended) launch Startup Repair' or 'Start Windows normally'.

  When I select repair system, the screen turns off for half a second only and brings back me to the exact page as I was already on.

  When I select "Start Windows normally", he brings me to the loading screen that usually starts with Vista (anyone who says (c) Microsoft Corporation), except that it never stops loading.  I left for hours, and he was still on the same screen.

  I have a laptop Dell Inspiron 1525 with a processor Intel Core 2 Duo and Windows Vista Basic.

  Follow these steps to try to solve your problems of boot.

   

   

  Restore point:

  Try typing F8 at startup and in the list of Boot selections, select Mode safe using ARROW top to go there > and then press ENTER.

  Try a restore of the system once, to choose a Restore Point prior to your problem...

  Click Start > programs > Accessories > system tools > system restore > choose another time > next > etc.

  ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

   

  If restore work not and you do not have a Vista DVD from Microsoft, do a repair disc to do a Startup Repair:

  Download the ISO on the link provided and make a record of repair time it starts.

  Go to your Bios/Setup, or the Boot Menu at startup and change the Boot order to make the DVD/CD drive 1st in the boot order, then reboot with the disk in the drive.

  At the startup/power on you should see at the bottom of the screen either F2 or DELETE, go to Setup/Bios or F12 for the Boot Menu.

  When you have changed that, insert the Bootable disk you did in the drive and reboot.

  Link above shows what the process looks like and a manual, it load the repair options.

  NeoSmart containing the content of the Windows Vista DVD 'Recovery Centre', as we refer to him. It cannot be used to install or reinstall Windows Vista, and is just a Windows PE interface to recovering your PC. Technically, we could re-create this installation with downloadable media media freely from Microsoft (namely the Microsoft WAIK, several gigabyte download); but it is pretty darn decent of Microsoft to present Windows users who might not be able to create such a thing on their own.

  Read all the info on the website on how to create and use:

  It's a very good Vista startup repair disk.

  Data recovery:

  1. slave of your hard drive in another computer and read/save your data out there.

  2. put your Hard drive in a USB hard drive case, plug it into another computer and read/save from there.

  3 Alternatively, use Knoppix Live CD to recover data:

  After installing above ISO burning software, right click on the Knoppix ISO file > copy the Image to a CD.

  Knoppix is not installed on your PC; use only the resources of your PC, RAM, graphics etc.

  Change the boot order in YOUR computer/laptop to the CD/DVD Drive 1^st in the boot order.

  Plug a Flash Drive/Memory Stick, BOOT with the Live CD, and you should be able to read the hard drive.

  When the desktop loads, you will see at least two drive hard icons on the desktop (one for your hard drive) and one for the USB key.

  Click on the icons of hard drive to open and to understand which drive is which.

  Click the icon for the USB drive and click on "Actions > Change the read/write mode" so you can write to disk (it is read-only by default for security reasons).

  Now to find the files you want to back up, just drag and drop them on the USB. When you're done, shut down the system and remove the USB key.

• System does not boot

  Nothing happens after the diagnosis of start-up game. Screen displays the message "windows did not start correctly last time" and gives options. No work and when the countdown ends at "load windows normally", system freezes.

  The restore disk provided allows only a hard drive formatted and reinstalled but I have all my music, photos and other work, including important emails, on the phone and that you do not have a back upward.

  How can I start windows from a CD so I can remove my docs on an external hard drive before formatting? Help, please!

  Hi Julian,.

  Your easiest option would be to remove the hard drive from your laptop and install it in a USB Caddy which you could then fix it on another PC and copy your data. Could then just reformat/reinstallation of your system using the recovery CD.

  If you have access to a genuine Microsoft installation CD then you could try to boot from that and try to repair your existing operating system but I don't think that you would be able to copy your data using this technique.

  Finally, you could use a bootable CD of one of the utilities of commercial backup/restore (like Norton Ghost or Acronis True Image) and try to unload your data on an external by using this utility.

  Kind regards
