PC Just shut off!

[chains716]

Hello,
Built my own kit and the the pc was working fine for weeks. yesterday the whole thing just shuts down after playing Guild Wars for 30 mins. I get lights on the motherboard but nothing else is working. Any ideas?

Current build is:
Corsair TW750
Geforce GTX480
Windows 7
Coolermaster Tower
Intel i5-2500
WD Caviar 500gb
2 Ripjaws Memory
and a Crucial 64 MB SATA.

Any ideas? I am thinking it is the power supply but unsure since this is my first build.

Thanks!

Corey

Power supply should be fine. I'd guess your gtx480 overheated. Try booting without the card and see if everything else works fine.

UNplug the Computer from the wall once it is unplugged hit the power button a few times then plug it back in and turn it on what the POST screen for erros like CPU or over heat warning,

see if your case power cord it faulty by starting your system using your a screw driver and leave the case power cord unplugged
go to 14:20 and watch from there

if it happens again after you do all of this then its probably is either the cpu, motherboard, or psu

you shouldnt have any problems when you put the GPU back in.

The system wont turn on when I replace the GC, if I take it out the pc starts up normally. I guess it is a bad graphics card.

Thanks!
