A little while ago i noticed that my computer had started to restart or completely shut down on its own randomly when i was using it. The computer has gotten slower over the years (its about 5 years old) and when i shut down on its own again today i decided that i would just reformat the whole thing. So I just finished doing the disk recovery thing and i transferred over some old files that i had backed up from before onto another hard drive and I was just installing a game back onto the computer a few moments ago when the computer restarted by itself again! when it came back i started my browser and it did it again a second time. Anyway I was wondering what the hell is going on with this thing, could it be some of the files i backed up and transferred over? Im running windows XP any additional info you guys need about the PC or what i have on it ill tell you, but please I really need some help I cant have this happening over and over again. please help guys, thanks.
