You may also receive a "Stop 0x0000007B" error message during Windows XP Setup when the Setup program restarts during the installation process. When you receive a Stop error while the Setup program is running, you receive the second error message. To troubleshoot this issue, read the following four sections to determine if any one of the issues applies to you. If none of the issues apply to you, use the following general troubleshooting steps at the end of the article. Back to the top Boot-Sector Viruses You may receive a "Stop 0x0000007B" error message if your computer is infected with a boot-sector virus. If the problem is intermittent and you can start Windows, check your computer for viruses. If you find a virus, also check any floppy disks for viruses before you use them again.

For a list of antivirus software manufacturers, click the following article number to see the article in the Microsoft Knowledge Base: 49500 List of Antivirus Software Vendors Note You may have to use more than one brand of virus-detection software to detect and remove various viruses.

Important If your computer has been infected, it may be open to additional forms of attack. We recommend that you rebuild infected Internet-facing servers by following the guidelines that are published on the CERT Web site. Internet-facing servers are servers that function without a firewall or other protection. It is also a good idea to rebuild any other computers that are at risk because of their proximity to infected computers before you put them back in service.

If a virus has infected your Windows XP-based computer and a virus-detection program cannot remove the virus and repair the system, you must repartition and format your hard disk and reinstall Windows XP.

• A device driver that the computer boot controller needs is not configured to start during the startup process.
• A device driver that the computer boot controller needs is corrupted.
• Information in the Windows XP registry (information related to how the device drivers load during startup) is corrupted.

Windows XP requires a miniport driver to communicate with the hard disk controller that is used to start your computer. If Windows XP does not supply a device driver for your controller or if Windows XP is using a corrupted or incompatible driver, you must replace the driver with a valid copy that is compatible with your controller and Windows XP.

During the first phase of the Windows XP installation, Setup displays the following message at the bottom of the screen: Press F6 if you have to install a third-party SCSI or RAID driver. Press F6 and then follow the instructions to install a mass-storage device driver from your Original Equipment Manufacturer (OEM). For additional information about using F6 to load an OEM device driver to support, click the following article number to view the article in the Microsoft Knowledge Base: General Troubleshooting If none of the issues that have been described in this article apply to you, use the following general troubleshooting steps:

1. If you receive one of these error messages while you are installing Windows XP, update the computer BIOS or obtain Windows XP drivers for your hard disk controller (from the manufacturer of your computer, system board, or hard disk controller), or do both. For information about how to update your computer's BIOS or obtain Windows XP drivers, contact your computer manufacturer. For additional information about the availability of drivers, see the Device Driver Issues section in this article.
   
   Note: If Windows NT 4.0 or Windows 2000 was installed previously on a mirrored boot partition, see the Other Issues section in this article.
2. Use the Last Known Good Configuration feature. This may resolve the problem if you recently installed an incompatible device driver for your boot controller.

Hi! If its hanging on the welcome screen then its time to reinstall a fresh copy of windows xp. System collapses on any given time and the only cure is a windows reinstallation. Hope this helps and have a good one!

Hi,

Restart your computer. Immediately after the screen goes blank for the first time, press the F8 key repeatedly. The Windows Advanced Options menu appears. If the menu does not appear, restart your computer and try again. Use the cursor keys on your keyboard (your mouse will not work) to select Last Known Good Configuration, and then press ENTER. Windows XP attempts to start.

If you recently installed new hardware, shut down your computer and disconnect the hardware. Then, restart Windows XP and troubleshoot your hardware to get it working properly.

Restart your computer and press F8 again. This time, choose Safe Mode and press ENTER. Windows XP attempts to start in Safe Mode, which does not automatically start programs and hardware, and displays very primitive graphics. If Windows XP starts successfully in Safe Mode, you can remove any programs or updates you have recently installed. Then, restart your computer normally.


Good luck!
And Thanks.

Try cleaning up your unused programs and files using disk cleanup and defragment your drive using disk defragmenter.
To formaer your drive and reinstall the OS, run the computers recovery wizard, or insert the recovery disk that came with your computer.
If you do not ahve a recovery disk or recovery program, use a windows installation disk like windows vista, windows XP DVD to format and reinstall the OS.
Make sure to backup the stuff you want before attempting this!

You need to reinstall the os. you might learn that copying file will be an option but thats not a good option. after NTLDR, tehre are 7 other files you may need to copy. so simply and easiest way is to reisntall the os.

step 1. You can press <Alt+F10> or the Empowering Key to launch in a Windows environment, or press <Alt+F10> during boot up. For the Veriton desktop series, you can also press the hardware reset button at any time. For the Aspire or AcerPower desktop series, an Acer eRecovery Management icon can be found on the desktop screen.
If this fails.

step 2


Back up all data on your computer before reinstalling. Insert the Windows XP disk and restart your computer.

Press any key when prompted to begin running the disk.

Press F8 to agree to the terms of service.

Choose the partition you want to reinstall Windows XP on. This is usually "C:" for most users.

Choose the type of format. You can choose either "Quick" or "Full" for NTFS systems. A quick format only takes a few minutes less than the full format.

Wait for the format to complete. The Windows XP installation wizard will begin. You will be asked to choose your time zone, computer name, and to input any network information. Otherwise, the reinstall will run by itself.

Warning!

The prompts during the reinstall will occur 10 to 15 minutes after the wizard begins. Use the original product key or the Windows XP installation will not activate. You will need to call Microsoft if your product does not activate. The number is listed on the activation window. This process will cause data loss.

Hi and welcome to Fixya..

Reinstalling Windows XP on an Acer Aspire 3000 is fairly straightforward. You may need to reinstall Windows XP due to hardware failure, a virus infection, major hardware changes or a hard drive upgrade. Whatever the reason, you can do the reinstall yourself at home. The reinstall will take anywhere from 1 1/2 to 3 hours, depending on the size of your hard drive. Be aware that reinstalling Windows XP will format your hard drive, getting rid of all data on, so you'll want to back it all up on a media device.

• Step 1

Back up all data on your computer before reinstalling.

Step 2 Insert the Windows XP disk and restart your computer.

Step 3 Press any key when prompted to begin running the disk.

Step 4 Press F8 to agree to the terms of service.

Step 5 Choose the partition you want to reinstall Windows XP on. This is usually "C:" for most users.

Step 6 Choose the type of format. You can choose either "Quick" or "Full" for NTFS systems. A quick format only takes a few minutes less than the full format.

Step 7 Wait for the format to complete. The Windows XP installation wizard will begin. You will be asked to choose your time zone, computer name, and to input any network information. Otherwise, the reinstall will run by itself.

I hope this helps

Is the disk you have xp pro? If not, just do the xp home or whatever is on the disk. You may have to format your hard drive to clear it to accept the windows. Get plenty of advise before you do anything permanent like formating your hard drive. Get any factory disks that you can that will have your bios on them.

if the system was able to enter the desktop and restarts...once possible cause is a virus...scan the pc via safemode or reinstall windows.

but if it didn't enter the OS desktop...cause might be the boot loader or MBR is damage..

worth a try:
