Like I said in title,my computer is running like a horse untill I open an game! After playing 10-15minutes my PC is restarting itself! I tryed out some tweaks that I founded on the internet,but still nothing! Anyone can help me with this?
Spec:
OS: Windows 8 x64
CPU: Intel Pentium Dual Core 1.6GHz
GPU: nvidia GT 9500 GS
RAM: 2GB ddr2
Motherboard MSI 7502
PSU: 400Watts
P.S.: I removed all useless hardware like DVD/Writer and Extra Coolers! This problem started about 1 month ago,but from few days is frequently!
 
Solution
PSU is old and dying, and cannot handle the GPU anymore. It is probably some no name brand, low quality unit, to begin with. Do not go out an just buy the cheapest PSU you see either. You will need to make sure you are getting one of decent quality.

It isn't a performance issue here, it is an issue of the PC shutting off and restarting itself. I suspect PSU is on its way out.

So,because of you guys,I reduced the issue to 3ways:
The PSU that might be on dead end
The alimentation cable,that it's not fixed very well in it's place,if I shake it a bit,my computer turn off
The Surge protector!
I'll try to replace them at a time! Hope it's not the HDD!

Well,I don't replaced the PSU,but I removed my GPU and enabled integrated one,and no restart!
Can you guys tell me,it's there a problem with my GPU or the GPU is consuming so much power from PSU?
