What happens is that the image on the screen is completely black and the monitor loses signal to the graphics card ( computer freezes st the same time and sound disappear ) after a few minutes of using the computer. It doesn't matter what I'm doing, it is equally likely to happen when I surf as when I game.
I suspected pretty fast that it either had something to do with power saving settings of the screen ( which it did not - I had set everything to " never " ) , or the video card that getting too hot, which wasn't the case either, as I without problems could stress test the graphics card and see it happily get past 70c but then crash one minute later while back down at 60c again.
I'm not going to rule that out completely yet though.. the GPU fan is running louder than it usually does when the PC is idle (I can currently hear it as I've been running disk checks all night). Perhaps it's a HDD overheating?

Specs :
Win7 Pro 64 Bit
AMD Phenom 965 BE @ 3,5 GHz + Cooler Master Hyper 212 + evo
EVGA GTX 570 OC
6GB of DDR3 RAM
1x Samsung 840 SSD @ 128GB
1x IDE HDD @ 465 GB
1x SATA HDD @ 465 GB
1x SATA HDD @ 2TB
Samsung BX2431 24" screen
MSI 870- C45
Antec VP650P PSU @ 650W

The disk checks seem to be stuck in a loop - sort of. I scheduled all 4 of my disks to be checked after restart at the same time, and now it seems to just check the same disk over and over again (while sometimes checking another disk, it always comes back to the same disk), but it never reports any error.

Oh, and I will get another monitor to check if my monitor is broken, but that is not an option right now so let's pretend that isn't the case.

60c-70c is normal. So don't worry about it much.
dskchk will let you if there are any bad areas. yes this takes very long time. symptoms doesn't indicate HDD problem.

No problem with monitor as you said see there is break in Audio too.

Did you install any new drivers? or hardware?

No. As a matter of fact I have actually procrastinated updating my nvidia drivers for a while. Could that be an issue? As for other drivers, I don't recall manually updating any drivers within the last week or so, but something might have been installed automatically. I'm not too sure.

The thing with loss of audio is basically.. I am in a skype call and the screen just cuts black, so I lose the audio from skype or the capability to speak back to whomever I am in a call with, as well as the rest of the audio output on the whole PC. I am not able to do anything else on the PC while the screen is off as well, so yeah, I agree when you're saying that the monitor is probably not at fault here.

EDIT: No new hardware.

UPDATE

So, I think my PSU is dying on me. I noticed that I was actually wrong in my description and the black screens pretty much only happens while gaming - e.g, when the GPU is at 100% usage. That one time it did black screen when I was outside a game I was running furmark, so yeah..

Basically, to test my theories, I downloaded MSI Afterburner and downclocked the shaders of my GPU from ~800mhz to 500, and ran a demo in CS:GO (which is basically equal to playing a match GPU usage wise). It worked fine for a minute or two, but as soon as I popped the clock back to its original state (~800mhz) the screen instantly turned black on me and I heard my GPU fan die. So, my conclusion from this is that my PSU is dying, yes? It can't handle the power usage of my GPU anymore when it's in full load, right? Or is it my GPU that is dying? Ugh, this is so confusing..

|I don't think your GPU is dying. Nice work there. You almost solved your problem. looks like PSU is unable to supply enough power which explain loss of audio also. Try someother PSU and get it confirmed.

Thank you. I will be buying a new PSU eventually, http://www.newegg.com/Product/Product.aspx?Item=N82E168... <- this is the one I'm planning on getting. I've heard Corsair is a fairly reputable brand, as long as you avoid the CX2 series, is this correct?

Anyways, considering how my GTX 570 has a "minimum" requirement of 550w, and I am currently using an aftermarket cooler for my CPU as well as 4 hard drives, I'm not surprised if I was probably maxing out my PSU already before it started failing on me, so I figured I'd get some more headroom this time. Also, this current PSU is not 80+ certified and is generally just a cheap PSU, so I'd say good riddance.

Yes that PSU looks good. Though 750 will be overkill it good have it in case of any future up-gradation.

Good luck.

--UPDATE--

Bought a new PSU. An XFX ProSeries 650W is what I bought. After installing it and booting up the PC again, I can, unfortuantely, report that the problem persists. Did some testing with clock speeds and I get the same results as I did with my old PSU. GPU runs fine with a core clock of 400mhz, but not with stock speeds (700mhz) or the factory OC that this card came with (800mhz). Did some monitoring as well as logging to check temps when the GPU crashed. Temps were at 63c, so that was definitely not the problem.

Another funny thing I noticed was that when this happens the GPU fan is still running, so the issue is not the power delivery to my GPU, but most likely the GPU itself. I tried reverting back to old drivers using driver sweeper (went back to 314.22), and this did not help either. I am now starting to believe that my GPU is just simply broken, but I guess I never wanted to believe that since I don't have the money to upgrade to a card with similar performance at the moment and it seemed unlikely to me as the GPU still sort of works. Oh well :/  Any ideas, people?

Hi. I have the very same problem and symptoms as you have.
Monitor and sound shuts down randomly after couple of minutes. Gpu fan keeps running.
The only addition I made is a new mouse razer mamba 2012.
My pc:
Gigabyte z68
2x8gb ram
180gb ssd + 500gb + 2tb + 3tb
Gigabyte x280 gpu
