[SOLVED] Screen goes black at very random times, PC still running.

[TuxNTopHat]

Twice now my screen has gone completely black, and the PC is still running. Fans stay at the speeds they were, and Windows is also still running from what I can tell.

The first time, it happened after the PC was on for a couple of hours and then left to sit for some 20 minutes, and the second happened while I was web browsing.

The monitor does not turn off, rather the screen renders black over the entire screen. This system was just built days ago. The GPU has been fine during gaming sessions and video-watching for hours, and this issue is 'solved' by forcefully powering off the machine and restarting it.

The GPU is an AMD R7 260x with most recent catalyst drivers, and I have Windows 7 Ultimate.

Any help is appreciated. I'll give you a cookie. ( a physical food-type cookie, that is. )

I, tentatively, appear to be stable atm. The solution was to upgrade to Catalyst 14.7 beta drivers.


OLD:
[strike]The problem returned the next day (meaning my c state settings changed nothing). I am at a total loss atm what the problem could be. Jurge92 your set up is very similar to mine, were you able to identify the problem?[/strike]


OLDer:
[strike]I had the same problem as OP. The fix was disabling C-states in UEFI bios (specifically state 3 (sleep)). Even if you set your comp to never sleep in windows settings it doesn't effect the c-state. I found I could leave all c-states enabled and just changed UEFI to allow usb keyboard/mouse to wake comp.

Please can you post the link to the drivers, I can't find them

I'm going to RMA the card very soon.

The black screens have indeed stopped. The GPU IS the problem, but I'm pretty sure the drivers have nothing to do with it.

OP, are you still under the impression it is the GPU? I also have this issue and I have a Radeon R7 260. Unfortunately I did not find this forum in time and I bought new ram and a ssd and reinstalled my os only to have it happen again. The GPU was some weird Best Buy special. Doubt I have the reciept still. If the beta drivers work that would be great.

I think I found a solution!!!!! I had a similar problem for a long time and I could never figure it out.

After I overclocked, I found out my system actually seems to be more stable! I think this is because of adding more voltage to the CPU! It needs further testing but maybe applying just like +0.01 volts to a NON-overclocked CPU could fix this.

If the problem is GPU related how would OC'ing the CPU help? Do you mean increase the voltage to the GPU?

I don't believe it's GPU related. I RMAd my card and it didn't fix a thing.

I've got the exact same problem. My monitor turns black, and the led on the monitor goes from green to orange, indicating there's no signal. After a while, it will also say "no signal". Computer is still running tho.
This happens only during gaming, which made me think it was the graphic card. However, Ive run several gpu and cpu stress testes, and it all seems okay. I've also replaced the graphic card, and the problem persists.

I've got no idea what to do now.

Ps. Is a pretty new build. Problem have been from the very beginning.
