My little brother got a computer built for him by a professional.  However, it's been suddenly shutting down whenever anything is clicked or when he's playing on Nick.com.  I really need help FAST!!

he's got an AMD Mobile athlon processor in a ABIT NF7-M motherboard, 120 GIG HD, and a WIRELESS card in a PCI slot.

Thanks to all those who can help me!tryed a virus scan? doesn't sound like anything else except maybe a PSU problem. though it is unlikelyWe've done a slew of virus scans, so it's probably the CPU, right?not the CPU the Power Supply.... though i do dowbt that. If it was the PSU then it would be closing down more regularly. not beeing able to boot properly.


have you made any HARDWARE changes recently?Well, no not really,  It's a new power supply, I think....I'm gonna have to talk it over with my father who purchased most of the parts.  

I heard that it's more a Processor incompatability with the motherboard, but the MB was transfered from my computer (which it worked like gold) but I don't think anything was damaged in the transfer.  

We HAVE had the same problem with my dad's old comp, then the PSU shorted.  I think that may be it.
