BSOD while playing games

Welcome to SF!

I see no software problems, so let's jump directly to hardware.

What is the make/model of your PSU?

Try following these directions for Memtest: RAM - Test with Memtest86+

I'm not sure how you ran it in the first place, so I have to give that link.

Test hard drive: HD Diagnostic

It might be the PSU causing the problems. 650W is enough for most systems, but if it's a cheap one, it might still cause problems.

Could it be a heat problem? Test with Speedfan: SpeedFan - Access temperature sensor in your computer

Also, could you upload a CPU-Z report?

CPUID - System & hardware benchmark, monitoring, reporting

I see your RAM is running at 667MHz. It appears your motherboard has support for DDR3 2200+/1333/1066/800 MHz memory module, but not 667 MHz.

What RAM do you have? All I can gather from the CPU-Z report is that it is A-Data. Is that RAM capable of running at any of the speeds listed above?

If not, I recommend purchasing new RAM that does. The faster, the better.

I may end up contacting a RAM expert and observing him work, as I am new to the RAM scene myself.

Try setting the speed in the BIOS. See page 36: http://download.gigabyte.us/FileList...3lr_v1.1_e.pdf

Let me contact a RAM expert...he should post when he's available.
