Please help. my computer keeps crashing ever like 15min-2hours since turn on.?

Question

i had gotten viruses one day by an accidental download that once seeing it was wrong i canceled and even tho it had only been downloaded for 2 seconds my computer picked up a bunch of viruses, my old virus protector was way to slow and wouldn't help so i downloaded AVG 8.0 ( my friend told me to download it ) so i did a scan, deleted all the viruses, went into safe mode deleted the files with the viruses in them. and now theres no more viruses but yet my computer still crashes. im not that great with computers so if someone can help that'd be really nice.

Answer 1

some windows files have gone missing from your system

Boot your system with XP CD and repair the partition where XP is installed

That will be probably C drive

# Boot the computer using the XP CD. You may need to change the boot order in the system BIOS so the CD boots before the hard drive. Check your system documentation for steps to access the BIOS and change the boot order.

# When you see the "Welcome To Setup" screen, you will see the options below  

This portion of the Setup program prepares Microsoft

   Windows XP to run on your computer:

   To setup Windows XP now, press ENTER.

   To repair a Windows XP installation using Recovery Console, press R.

   To quit Setup without installing Windows XP, press F3.

# Press Enter to start the Windows Setup.



To setup Windows XP now and Repair Install , press ENTER. do not choose "To repair a Windows XP installation using the Recovery Console, press  R", (you Do Not want to load Recovery Console). I repeat, do not choose "To repair a Windows XP installation using the Recovery Console, press  R".

# Accept the License Agreement and Windows will search for existing Windows installations.

# Select the XP installation you want to repair from the list and press R to start the repair. If Repair is not one of the options, END setup. After the reboot read  Warning#2!

# Setup will copy the necessary files to the hard drive and reboot.  Do not press any key to boot from CD when the message appears. Setup will continue as if it were doing a clean install, but your applications and settings will remain intact.
