I have I problem with my windows xp, my PC is restarting when ever it wants.. some times its working for days but sometimes it restarting 5 times in an hour.. I've tryied with linux and its not restarting under linux, but when I went back to XP it started restarting again

My mom just bought a brand new HP computer with windows Vista,she had it for about 4 days and it was doing the same thing.. We called HP they tried to help but they couldn't fix it, we took it back to best buy and they found errors in the system from the manufacturer.. They replaced the whole system... Hope this helps...

Not at all.. I have the PC from 4 or 5 years, have to deal with it myself..

When was the last time you did some serious maintenance on your system ?
