Computer crashing while gaming?

[TheSurvivor]

Whenever I try to play any game that isn't browser-based, I crasher after I play a while.
When it crashes, it gives me a BCOD error and the monitor shuts off and the speakers start buzzing really loud.
I am not sure about the cause of this error, so can anyone help me and tell me what's going on?
I have already tried to underclock my video driver using MSI. I will see if I need to underclock it more.

Video Card: NVIDIA Geforce GT 220
Ram: 4GB
Operating System: Windows 7 32-bit
Approx. Total Memory: 2769 MB

I will try and use memtest and I will post again when I find out the results.

Track your gpu temp with afterburner.

I am %80 percent sure it is a gpu related hardware issue, %20 percent gpu related software issue. Check your gpu driver, power, clock etc, and try some kind of benchmarks to try to pinpoint the exact issue if drivers, power etc seem good.

It is not the same issue, he is getting that whenever he plays something that requires solid gpu performance. Your problem is probably caused by bad cooling, check your gpu temperatures.

Yeah, It most likely is, my case is open (so that my card will fit) and so that probably leads to higher temperatures. Should i increase the fan speed with Msi Afterburner?

I would suggest you to be sure that it is caused by temperature. (I would run a windowed benchmark while constantly checking gpu temprature and record the temperature when it crashes) then i would check if that temperature is within the range of operation temperature. If it is, then the problem is something else, if it is not, just as you suggested, i would go for better cooling (simplest way is rising the fan speed)

Fixed the problem-underclocked CPU megahertz from 260 to 190. THanks for all the support.
