Computer keep crashing

[Korea_xD]

I don't know why but if I play CS:S or any other games, my computer crashes.

I have:
Operating System: Windows 7
Processor: Intel Core i7 2.80GHz
RAM: DDR3 8GB
Graphics Card: ATI Radeon HD 4650 1GB
Hard Disk: 1TB (919GB)

Anyone know why?

Have you updated your graphics card drivers?

Blue screen? Or does it just go to the desktop?

It just turns off, no blue screen

I doubt this but you might have a virus.
Do you run alot of things while you play?
Have you installed/downloaded something and this just started to occur? If so try uninstalling it.

It could be your PSU....If it were someother peice of HW (ram, mobo, cpu) you would BSOD. Is there anything in your comp over a few years old?

if you have a crappy PSU it can go out in anywhere from .0001 seconds to 9001 years. time has nothing to do with it.
