I built a pc about 2 years ago. It is a custom loop water cooled i5 2500k, a sapphire hd 7870 ghz edition, 2x4gb intel extreme masters ram, wd 1tb hdd, rosewill bronze 1000w psu. Since probably a year ago it has been black screen crashing. The computer will not physically crash itself, all the fans will keep running at full speed from the sounds of it and i can normally still talk on skype and i still have sound to the game i was still playing. The crashes are sporadic. The screen will just randomly turn black and i will not be able to do anything and will be forced to reset the computer. I have tried everything i could think of: first i disabled my overclock (although it was running at safe voltages and temperatures i figured i would give it a shot), i disabled the boost clock on my gpu, i tried to down clock my gpu, i have ran just about every stress test i can think of and it still runs fine (it will only crash while gaming), ran windows memory diagnostic, even a system restore. The only thing i could still do but havent bothered to is put fresh thermal paste on the processor. Other than that, i do not have extra parts laying around to sub in 1 part at a time until the problem is resolved. Please help.

The i5-2500K does have an integrated Intel HD 3000 GPU.

You can take the GPU out and plug the monitor in to one of the video outputs on the motherboard to perform this test.

Not sure if your motherboard has on-board graphics you can plug your monitor into, and see if it black screens on you then if you do. I had a friend give me a computer that the stupid Geek Squad told him the motherboard was fried in order to sell him a new one, and it was only a bad graphics card that was black screening after a few minutes.

I figured it might be somewhere that is shorting out on the board, i just dont have another $200 laying around to buy a new one that might not even fix it. Where do i find the specs of my motherboard, like how much power it needs? and is there an application that i can download that will monitor the power draw of that 12v line? like how do i check it?

The motherboard has integrated graphics capability but my processor does not, it is strictly a cpu not an apu.
