• 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!

• 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!

• 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.

• 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.

• System does not boot into Windows when a USB is installed

  It's strange.  I just installed Windows 7 Home Premium Upgrade (64-bit) of a previous Vista machine.  Has made the choice of 'Upgrade '.  Now that it is finally installed and get some of the bugs resolved, a question I still have is when a (key, post HD) USB device is installed in the machine and I run a reboot or extinguished/turned on, the system starts to boot, runs through the BIOS section, but just before trying to start Windows I get a fast blinking cursor in the upper left of my screen.  If I remove all the devices usb between PC and manually must shut down and restart it restarts in Windows very well.  What is the problem?

  Desktop HP M9350F model; 64-bit; BIOS Rev 5,29 (28/04/09); BIOS Boot Priority: floppy, CD, HD, network (note: there is no other choice shown/available USB?)

  Maybe someone else has had this problem and an easy fix is avaiable.  Thank you!

  CD,

  Well believe it or not, I realized the problem.  Not the BIOS.

  One program, I have installed is SecureDoc WinMagic.  It's encryption software, although my drive has (yet) been encrypted.  In fact I had contacted the Lim before this same thread started to think it might be because of that, but he told me it was probably my BIOS and nothing to do with their SW.

  However, last night I decided to remove their SW before my "repair" operation was scheduled.  How to have this removed SW, it's just our curiosity, I decided to start once more with a USB device installed to see if the hang up has continued.   By my surprise, the start went as usual by means of windows and office.  DAMN!  all this time lost, mine and yours!

  I contacted the company SW this morning and they found a way to modify their SW and get the boot to work (always with the unencrypted disc).

  I wanted you and someone on this thread to know the outcome, so if this happens in the future with another user, this can help to avoid long-term on unnecessary troubleshooting.

  Thank you once again for all the time you have helped me with this issue!

• 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. MS - MVP - Elephant Boy computers - don't panic!

  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.

• "isass.exe system error indicates an encountered or specified revision number is not one known by the service." System does not boot.

  My roommate has downloaded a manual from LG Electronics cell phone in format .pdf (Adobe). The download is complete on Firefox. It double click on the download finished in the 'Download', its pc box became very slow and finally frozen. It is running Windows XP Media since 2004 / 2005.
  When it tried to reboot, the following message appeared...

  "... isass.exe system error indicates an encountered or specified revision number is not one known by the service." Continues it's maybe a more recent revision, then the service is aware of... »

  Then will continually attempt to restart. by a failure. Note the sequence of the events above are as accurate as the harshness.

  Does this mean the registry is damaged?

  Ran Iolo System Mechanic and has been able to run the tests in two (2). One of the physical drive and the other to the integrity of the partition. Nothing helps. A ran Norton recovery and found no errors. Performed a chkdsk /r and no mistake. Ran a chkdsk/p and found errors, but was not fixed. Any suggestions about where to start?

  I would like to thank all those who helped in my installation of Windows 8 Preview of consumer. He didn't find any problems of incompatibility with Norton a few months back and HP support said that the hard drive has been ruined, and I had to buy one of them after receiving the disks to install Win 7 again. Instead, I have used Drive Scrubber from Iolo System Mechanic and installed Win 7 perfectly. I'm now back with Windows 8. ALL of you are awseome!

• System does not boot up... message is... "" peripheral USB on the detected... current situation system turns off after 15 seconds.

  I recently bought a new golf gps device and connected to my desktop pc to register. After unplug his computer m USB cable I can't start my computer.

  whenever I start it the pc his usual routine, but then I saw the following message... USB device to the system detected. System turns off after 15 seconds.l

  Fifteen seconds after the system shuts down. It wiil also not afford to start or access the safe mode, the program installation or any other type of recovery mode, I could access normally. It will also not recognize my Win XP installation disc. I guess it's because of the configuration of the BIOS which accesses the hard drive before the CD rom drive.

  The problem was obviously created by the golf gps USB cable but I can't find a way to get the system to boot so I can find a way to eliminate the problem.

  Thanks for any help that anyone can provide. I am running WinXP Sp3

  Hi PAULARUNNELS,

  ·         What happens when you try to start in the Advanced startup options?

  ·         You receive the same error?

  ·         You external devices connected now?

  Try the following.

  Method 1: Disconnect external devices not essential, connected to the computer and restart the computer.

  Method 2: Load default BIOS (Basic Input\Output System) settings, and then restart the computer. Make sure that you have the CD drive set as first boot device. Check the settings by consulting the manual or call the manufacturer to do so.

  Note: Be careful when you change the BIOS settings. The BIOS interface is designed for advanced users, and it is possible to change a setting that can prevent your computer from starting properly.

  Method 3: If you are unable to start on one of the advanced startup options, and then you can follow this article.

  How do I recover from a corrupted registry that prevents Windows XP startup

• 64-bit with 4 GB of RAM installed; system does not boot

  I bought and installed W7 64 bit so that I could use the full 4 G of RAM installed in the machine.  Clean install after format but W7 would not move past the "Starting Windows" screen

  Microsoft is absolutely useless as Acer support.  Very disappointed in both.

  So I started by disconnecting equipment: card reader.  Try again.  Nope.  2nd screen.  Nope.  Remove the piece of 1 G of RAM.  There she goes. Now, I have everything set up and a few days later reinstall the 4 G of RAM.  Still, no way in front of the window startup.  Try changing on the sticks.  No go.

  So while Vista would go with the 4G installed, it wouldn't use it, W7 will not work with it.  Max 3G.  What gives?

  I think it must be in the BIOS, but what?  I also read that the removal of the video card and reinstall that after install the last piece of RAM will work, but I'm pretty skeptical.

• System does not boot after changing graphics card

  I'm under VMware ESXi 4.1 on HP xw8400 workstation. He worked well with HP Nvidia Quadro FX1400 graphics card, but after a while I became tired of all that noise and he changed his Asus Nvidia 7300LE. Now the system stucks on vfat successfully loaded.

  If I re - install the system with this another graphics card, it'll work?

  Strange that a simple graphics as blocked change the boot process.

  Maybe you order card PCI is also change.

  Simple, you can reinstall your host and then re-import the VMFS volumes.

  If you have local storage, make sure not to format the existing VMFS partition.

• Had to replace the motherboard: System does not boot, the XP installation disc runs to a failure.

  Thus, the motherboard in my PC started to die.  I replaced it.  Start-up of the new system has prompted a Safe Mode boot.  Choose Safe Mode, the system restarts after mup.sys.  Choose the last known good startup the initial windows screen appears briefly, then restart the system.  Boot from the original installation disk, all kinds of drivers charge then the last message that appears is loading Windows Executive.  A
  BSOD appears stating something to the effect of an error with the hard drive, verify the presence of virus, remove the new hard disks, etc..  Hard drives is a virus.  So, how do you round a re - install defective and/or repair or a defective Mode start safe mode with new material?

  Thank you

  Hello

  Since you have replaced the motherboard, you may need to reinstall the operating system.
