Win xp keeps rebooting after updating

Have run recovery console and did a chkdsk /p, no probloems there so I figure it must be a virus or something? update, I video taped the computer screen, and during the blue flash, what i could make from the video is ".been detected and windows has shut down..." "...

If your machine did not come with a Microsoft Windows Installation CD, try contacting the supplier or manufacturer for one.

If your machine came pre-installed with Windows may find that some applications need reinstalling after doing a Repair Install.

Any Windows updates will need to be reapplied after running a Repair Installation but his should happen automatically.

Some advice is given on doing this in a separate document.

If your Windows system is working sufficiently well, you can just follow the section on What to Back Up.
