Black Screen and Loud Buzzing Crash

For the last week or so Ive been having a problem while playing Darksiders. After about 15-30 minutes of playing, my computer crashes and it goes to a black screen, along with a loud buzzing sound from the speakers.

Ive googled the issue, and what I came up with was to try using MemTest 86 and Prime95 to see if there are any hardware failures. I even ran HWiNFO32 to see if maybe my cooling was awful, and it was the cause. But the temps seem within the realm of what it should be.

Ive run MemTest 86+ for over 2 hours without it recognizing a problem, as well as running a stress test with Prime95 for around 4 hours, all without any results. I havent been able to find any issues with my hardware using these tools.

I even upgraded my driver for my Graphics card, and that didnt help any either, although it did seem to let me last a little longer before the crash.

Anyone have any other ideas?

Here is the zip of my log from my HWiNFO32.

EDIT: My Hardware specs are in my Signature.

 

Speccy Works good on laptops might try that for your temps.

Yes if your laptop is going black then crash i would all so have to say it must be heat issue that is one major problem with laptops then really do not have the proper cooling system like desktop if the Cpu fan hasent been clean out in a while then there is most likely dust bunnys and thick dust might be on the fan.Take a Can of air to it and see if that helps.

 

Well I bought a new Rosewill Challenger case and swapped everything over to it and it seems to be working fine for the last 2 hours of playing. Seems like it was an overheating issue, considering this case has a whole lot more ventilation and 4x120mm fans and 1x140mm fan compared to my old case that had a 120mm and 2x80mm fans. Thanks for the help guys! Def way cheaper than new ram and/or a video card!

 

OK, spoke too soon. After playing for about 3.5 hours it crashed again. Gonna swap out my RAM and see if either one are bad. Hopefully its the newer RAM I bought, and not the older one.
