• Computer won't start; 3 long beeps, the fan turns

  Hello

  I have a desktop HP equipped of Windows Vista that does not start correctly.  When I turn it on it looks like it is starting, I hear the fan, the computer will beep 3 times in a row (I would say long beeps) then stops and beeps 3 times in a row again.  Then nothing on the monitor, fan always running.  If I didn't get anything I think that the computer and the monitor's energy-saving.

  Before I turn it on the screen says no signal so I think the screen itself works.  I don't quite see the HP splash screen.  Pressing F8 during startup seems to do nothing.

  I created Vista backup discs (food?), but I don't think they are bootable.  Some back story: a few weeks ago, I tried to download Windows Live.  After installing the updates, I could never Live DL and the next day I got the blue screen of death.  I rebooted, you press F8 repeatedly and Windows started normally.  Although it worked fine for a few days I felt nervous that I did a restore of the system around October 31.  Everything seems to be ok for over a week but now I have this problem.  I thought to upgrade to Windows 7, but do not know what to do at this point.  I've never opened a tour - answers Google talk out of ram or certain types of error of keyboard Bios (3270 keyboard card).

  Help, please!  Sorry to be so long.  :-)

• If my printer USB cable is connected, my computer won't start?

  If the printer is on and the USB port connected.  The computer won't start.  If I turn on the laptop with the USB plugged in and as it starts and then turn on the printer, everything works fine.  Almost ok.  I think I should be able to leave the printer on all the time as I do at work.  Then when I start the computer, the printer is ready.  Every other printer I've ever had worked this way.  Any suggestions?

  Maybe the printer looks like a hard drive (some printers have card readers that make them look like a disk) and the computer attempts to boot from the USB drive instead of the hard drive?  It would be a modification of the settings in the BIOS

• I have Windows 7, my computer does not start. I did the Startup Repair and he won't fix it. I did the system configuration information

  I have Windows 7, my computer does not start. I did the Startup Repair and he won't fix it. I did the system configuration information. and that did not help. What to do now? The comment of Bios makes me fear that it could damage my computer forever. What should do? Help, please

  Hi Alan,

  Thanks for posting your query in Microsoft Community.

  I understand that the computer does not restart even after running Startup Repair and I will be happy to answer your query. I appreciate the efforts made to try to make it work. Let me ask you;

  • How do you run the Startup Repair?
  • Do you have Windows 7 repair disc?
  • Remember to no particular change in the computer before the show?
  • Have you plugged an external equipment, except the keyboard and mouse?
  • You are able to start the computer in safe mode?
  • What is the brand and model of the computer?

  Note: BIOS change / semiconductor (CMOS) to complementary metal oxide settings can cause serious problems that may prevent your computer from starting properly. Microsoft cannot guarantee that problems resulting from the configuration of the BIOS/CMOS settings can be solved. Changes to settings are at your own risk.

  There could be several reasons why he's not leaving including hardware as well. In addition, it could be because the master boot record (MBR) has been damaged. When you try to use the Startup Repair tool to repair the MBR, the Startup Repair tool indicates that no problem was found or it does not work yet.

  If you have any connected USB flash drive or other external devices connected to the computer, if you please, remove them and try to run the Startup Repair tool.

  If you haven't tried using Windows 7 repair disc, you can try the following:

  1. Insert the Windows 7 disc
  2. restart your computer
  3. When asked if you want to boot from your DVD player, do it.
  4. Select your language, click Next.
  5. click on repair your computer
  6. Select the operating system you want to repair.

  You can also perform the system restore by selecting the restore point when you think it worked very well. System Restore, choose advanced options using the disc.

  Important: When you use system restore to restore the computer to a previous state, the programs and updates that you have installed after this date are deleted.

  I also recommend to contact the computer manufacturer to get the done diagnostic equipment.

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

  6 Lightroom unbootable after an update... I reinstalled the software, but it still won't start? Updated through the creative cloud but still does not start?  What should do?

  My computer is a PC with Windows 10.
  Everything worked well before the Update Adobe Lightroom 6.
  The software was purchased in a shop (FNAC) with software to download map, it is saved in my account (Adobe) with its serial number. Why is this so difficult thing to reinstall Adobe software?
  

  
  

  I apologize for the inconvenience.

  Since it appears and disappears from the Task Manager, it seems that Lightroom crashes.

  We have seen this kind of problem on Windows 10 when Visual C++ Reditsributable 2012 update 4 is not installed correctly, it is necessary to run certain programs. You might have encountered until now Adobe programs that require it.

  Otherwise, there could be another cause of this accident and if C++ installation does not help, then you need to share the event viewer crash logs. See this article for in crash logs: Photoshop Elements Editor Help. How to find the crash logs on to Windows

• My computer will not start, getting warning that the iertutil.dll is missing for Internet Explorer

  Anyone know how to fix this problem? I get a warning saying that the iertutil.dll file is missing for internet explore. When I start my computer, all I get is my screensaver with no office. The only way I can continue any part of my computer is to go to alt del to get to the control task manager.

  Do you mean you see a message like this:

  Explorer.EXE - unable to locate component
  This application has failed to start because iertutil.dll was not found. Reinstalling the application may fix this problem.

  That file should never be missed and it takes an extra effort to remove it on purpose because there are one of 3498 files who cares about Protection of file Windows (WFP).

  If explorer.exe is not running, all you will see is your screen background image.

  The file is in this folder (assuming that XP is installed on your C drive):

  c:\Windows\System32

  Since you can get into the Task Manager do the following:

  Since the Task Manager, click file, new task (run...) and then click Browse and navigate to this folder:

  c:\Windows\System32\dllcache

  If you are unable to find or do not see the dllcache folder, because your system is not configured to display hidden files and folders, simply type the path to the folder name in the "Open:" box

  c:\Windows\System32\dllcache

  Make sure the "Files of type" box is set to show all files (or you will not see any), and then click OK to display all files.

  Locate copy the iertutil.dll file backup in the folder c:\windows\system32\dllcache, made a right click and copy and go back up a folder c:\windows\system32, right-click in an empty area and paste the file there.  Answered in the affirmative if invited to replace the existing file.

  If you can't find the file in the dllcache folder (should be), depending on your installation, there may be a copy of the file on your system in this folder:

  c:\windows\ServicePackFiles\i386

  If you find there, copy the file missing from there and paste it where it belongs

  It is possible that some malicious software or your antivirus/antimalware indeterminate quarantined (actually deleted) the right file and the backup copy of which must be in the dllcache folder.

  In this case, you can download a copy of my SkyDrive and use networks disks (on foot) to bring it to the system afflicted on a USB key or a floppy disk.

  You may be able to 'Run' iexplore.exe in the Task Manager to get on the Internet and just download it.

  I downloaded a copy of XP Pro SP3 file you need on my SkyDrive (everyone has a SkyDrive for file sharing).

  You can download it and when you do, place a copy of the file in these two folders (assuming that Windows is installed on your C drive):

  c:\Windows\System32
  c:\Windows\System32\dllcache (this is where XP keeps backups of important files).

  Here is the link to my SkyDrive and you can get the file you need here:

  http://CID-6a7e789cab1d6f39.SkyDrive.live.com/redir.aspx?RESID=6A7E789CAB1D6F39! 311

  When you see the files available for download, you will not see the extension of file (.exe, .dll, .cpl, .sys, etc), but when download you them they will have the right extension.

  When you download the file (especially if you use Internet Explorer), when you get a chance to save the file, it cannot save the file with an extension (for example, .exe, .dll, .cpl, .sys) then you will need to manually add the extension appropriate to the file when you download the file before you save it.

  You can download the file without the extension, and then rename the file to add the appropriate extension.  You do not want to use a file called rundll32 when the name of the file should really be called rundll32.exe (if the downloaded file has no extension, you will need to change the name of the file to add the appropriate extension to make it work.

  You then put the downloaded files in the correct folders on your system.

  That may not solve all your problems, but at least you will be spending this part and we can then fix the rest.

  Since it is all very suspicious to meI would follow with this:

  Download, install, update and do a full scan with these free malware detection programs at:
  Malwarebytes (MMFA): http://malwarebytes.org/
  SUPERAntiSpyware: (SAS): http://www.superantispyware.com/
  They can be uninstalled later if you wish.
  Restart your computer and solve the outstanding issues.

  I found KB981957 to be the culprit on that I worked on a system of XP SP3.  With this update installed, I get an error C000021A Service Control Manager BSOD.  I have manually uninstalled this update by using the Recovery Console and then used Windows Update through IE and deselected this update.  All the other updates installed correctly and the system starts properly.  I would like to know why this update is causing this problem.  Anyone with the same problem?

  It reminds me of a similar situation earlier this year with BSOD KB991765.  The cause of the BSOD is a virus that has infected system driver files.  Once clean, the installation worked very well.  I've done many scans on this system and have not yet found any viruses.

• Computer won't start and the screen is weird looking

  After the maid left today, I noticed my computer screen on my DELL PC running Windows XP HOME Edition (service pack 2 or 3 - I don't know) seemed strange. The pixels have been weird in several areas of the screen and the cursor froze.  I tried to turn off the computer, but it will turn off, then I disconnected and finally had to hold the power switch on the CPU for a few seconds to turn it off.  When I tried to turn it back on again, it showed Windows startup to the top of page - but the screen still seemed weird - kind of out of touch.  The computer does not start.  It's just a black screen with a cursor in the middle of the screen is frozen and the mouse does not move.  I tried to push the F-8 when starting Windows screen came. He took me to a different boot options menu, but always with the print-screen out of phase. I tried a few startup options, but it just brought me back to the Windows boot screen with the logo being shifted - sort of split and strange looking.  Is it possible that my maid has done something to the computer, wiping down? Is it possible to fix this? It's never happened before. Can someone PLEASE?  Thank you

  Hi Goldie309,

  I suggest that you reset the default monitor settings using the buttons available on the computer screen and check if that helps.

  You can also connect another monitor to the computer to check if the monitor is defective.

• computer won't start, replaced power has not set

  I had a problem for the last few weeks when I try to turn on 1 of my computers, initially, it would not just usually turn on and start. I would like to press the button and it would flick amber a second but not turn on. Sometimes it turns on after hours and the last times that the internet on it had become very slow, and yet the same internet worked fine on the computer that I use to post with. The computer itself was not slow, just the internet about it. I don't know how this could be related, but I guess it must be related to my problem given that the Internet is fine on my other computer. The fan on the computer also was not working but replace the PSU which set.

  
  Also, not sure if this is related, but until this problem occurs the computer freezes a lot and I have to force it off the coast. Or he would break himself. I don't know what message it would but it would go to the black screen of death and mention something about an internal clock, then restart itself.

  I removed the Mcafee antivirus software a few weeks before and downloaded Microsoft virus softwear on the same day. Other then that I did not any changes to the computer recently. I use a Dell Studio xps 435MT with vista. I checked and all drivers are updated.

  Here are the steps I did the last time that I was able to get on this weeks trying to understand the problem: I have run the dell diagnostic test and it detected no problems. I also looked in the event viewer, but there's a lot of mistakes, so I don't know if it could cause a problem. Memory diagnostics have been run, and no problem found there. A comprehensive analysis was performed as well and it detected no viruses.

  Since then, I've replaced the power supply and now instead of light, flicking a second flashing repeatable, yet does not turn upward. Fan works again tho so it's good, I guess.  Power supply is compatible and right hook. Before purchase power supply also bought the new point of sale, so that obviously wasn't the problem etiher.

  Please help me I need this computer works again one I am on now is much older and slower.
