Random and frequent BSODs - Windows 7

[yolomeister]

What happens is the screen goes black, audio stutters, my fans get really loud, and the computer either reboots itself or needs to be manually rebooted.

I have updated my drivers, the fans are clear, temps are good, I do regular system cleans with CCleaner, and I don't do stupid things with my computer (I'm sure it doesn't have a virus).

Windows 7 custom built PC.

Almost all of the error codes were BCCode 116, but there was one BCCode 117 and one BCCode 50. Here are 2 of them.

Dude what Graphics card are you using? and what power supply are you running it on?

 

[yolomeister]

Thanks for your response . Running ASUS GTX570 DCII on 850WPSU, have never had problems in the 1.5 years of using this computer.

Have you opened up the case recently? I mean before all this started. Or installed anything that might effect your video card in some manner? I've had a similar issue that was caused by a power cable that had come just barely loose, which I swear I didn't even touch.

Thanks for your time as well . Yes, I clean and open my case very regularly. I will check for loose connections again (more thoroughly this time). Is there any way to tell where specifically to start looking?

24-pin and 8-pin connectors leading to the motherboard and the PCI-E 8-pins, 6-pins, 6+2-pins whatever you got going to the graphics card. Suppose you could check the HDD power and data cables as well on both ends.

An obvious thing to do is to try using another GPU from another system that is known to work and trying the failing GPU on a working system. You could also try other operating systems to see how they behave. Once the power connections are ruled out as the culprit then maybe the conclusion is that the GPU is about to give up the ghost. Try and see how it behaves when under load, e.g. by running a benchmark like unigine heaven or similar for an extended period.

I have checked the cables, and all are fine. Unfortunately I am unable to obtain another video card to test. The card is very powerful and handles games sometimes for hours on end without any issues, then crashes while idle. So I believe the answer is in the error files. Does anybody know how I (or where somebody else) can analyze them to find the source of the problem?
