ok heres the deal.....my computer is kinda working weirdely.......at first it shuts off without any reason while i was on the net or playing some game........went to some computer guy......formated and brought the CPU home...now still its shut off sometimes and certain times its working perfectly......like sometime i play some heavy duty game and still it works fine.....but sometime...iam jst surfing the net and it shuts off and then restart again.....i repeat there are no viruses becuase i got it formated and there is no voltage problem cuz i got a UPS and it is working fine.....so can anybody tell me what the hell should i do...???

that's the problen bcoz of ur ram chip so firstly unplug it from the slot nd clean both the ram nd ram slot then plug it again if the problem continue then if possible change the ram if in warrenty period otherwise u hv 2 continue with this problem untill u replace ur ram with new oneeeeeeeee

it may be a problem wid the fan inur CPU...if it aint workin properly the temp increases...n the CPU is made such tht beyond a particular temp it shuts down...so plz chk the fan

ur hard disk might b very old one !!

get a new 1 !! it might solve ur problem !!

or even SMPS might b not gud !!!

but most probably if restarts automatically is d problem den ur hard disk is in complaint !!!

I doubt its a problem with the fan / smps since its working fine even under heavy duty gaming. check your ram / hard disk, thats probably the problem. which windows do you have?
