Go to control pannel and open power options and see it it is set to shut down in a short time slot.
if this isn't it post again.
Okay, I recently got spyware downloaded onto my friend's computer by clicking on some site to change my AIM buddy Icon. Anywho, I had pretty much gotten rid of the bulk of it using Adaware, Spybot, Micrsoft Anti-Spyware(Beta), and Hijack This. She gets on and clicks on some pop-up, so now theres more. Once again, a lot of it is gone, but we still get a pop-up every ten minutes or so.
I also downloaded the Windows XP updates, including SP2, and SP2 seemed to bring problems. It kept giving me an error message that said 'A Serious System Error Has Occured', but I fixed that by uninistalling SP2, then reinstalling it, and doing something else, but I forget what.
And now, for some reason, it restarts while browsing the web. Also, if the computer is idle, it seems to restart. It's not restarting a lot, but still, it shouldn't be doing that.
I checked the microsoft web site, and they gave me some instructions. I can't get online yet, though. Are there any other suggestions out there? Thanks.
