Closed Solved

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

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.

First time happened after the PC was on for a couple of hours and then left to sit for some 20 minutes, and the second 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. 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. :D )

More about screen black random times running
  1. Check and see if sleep mode or screen saver is is enabled, after X amount of time it would black out, or will go to a screen saver if any is set up

    Sleep has nothing to do with it for sure, I checked that. Hmm I may have to RMA the GPU.
  3. Have you checked your cable? Especially if using HDMI?

    Yeah, maybe I should replace it and see how it goes.
    It's a VGA cable with an adapter for DVI on the GPU end.
  5. Best answer
    Get a VGA to DVI-I (that carries an analog signal in it)
  6. Alrighty then. Should have one in a box somewhere.
    I'll also try fiddling with the power cable setup, is there anything weird with connecting the GPU's power among the string of fan cables? I hope there isn't.
  7. Shouldn't be a problem, keep me updated ;)

    Entire day of it running. Gaming, web, research, documents, photoshop.
    No black screen, so far so good. HDMI to DVI is the new cable beig used, and I replaced the power plug to the GPU with the one included with the power supply. One of them may have worked.

    I'll just complain here if it happens again over the next few days. Either way, thanks a bunch. :D
  9. No worries, glad to hear all is better, have fun !

    Nope, worries are back. Happened again, but this time the monitor wasn't picking up a signal at all. I suppose that's the difference it made.. From a black screen, to the monitor suddenly thinking the PC isn't there.
    Happens at the same interval of <randomtimegoeshere>.

    I don't think it's the monitor really, but the GPU works fine at all other times, no throttling, just perfection.

    Isn't 500 watts enough for an AMD Radeon R7 260x? I suppose it isn't power either...
  11. 450 or so should be plenty (w/ 19/20 AMPs on the 12 volt) what PSU? Might be one advertised as 500 and that might be peak, continuous could be much lower

    Corsair CX500m. Seems fine to me.

    Also, I just updated the bios, that may or may not help, says the internet.
  13. Let us know if the BIOS helps
  14. I have same issue with the OP, random black screen during Gaming/Videos. just bought my Rig last Mar 2. Specs are listed below:
    FX-6300
    Asrock 970 pro3 r2.0
    Ripjaw 2x2Gb
    Powercolor R7 260x 2Gb OC ed
    Corsair VS550

    I have alreadychecked the GPU temperature; it is around 55C~70C under load. Hope you could help me. Thanks

    Happened again.
    BIOS updated, changed the type of cable used for the GPU's power and video.

    Nothing works. I'm lost.

    For the next 3-7 days I'm going to use the integrated graphics to ensure it's GPU related, any thoughts much appreciated. This problem is pretty odd.

    (I hope it's the monitor's fault so so much, but at this point it couldn't be, could it?)
  16. You can try the new beta drivers from AMD for your graphics card. I have a similar problem with AMD R290. seems to be driver/bios related. if it doesnt work , best solution is to RMA the card.

    If the black screens have stopped now that I'm not using the GPU, I'll try that.

    Also after doing a bit more research, it could be from motherboard static or from cleaning out the RAM/PCI slots. I'll try that as well.

    Most likely it's because of the evil fairy god of death's magical powers, but that's my opinion.
  18. May Be, think I've run into that fairy or her sisters a time or two ;)
  19. Alright, I'm really sure it was the GPU.
    If it is some crazy funky power-related issue, it could happen again in a while. But I highly doubt it.

    So the GPU is out and for 3-4 days, no black screen.
    after a few days, I'll put the GPU back in and try the latest beta drivers, but I think the card is pooped.
    I'll probably have to RMA the card.
  20. Sounds like it, keep us updated when you try it again
  21. I have this exact issue. I have also noticed that the PC is unresponsive while the screen is black(monitor is on, using DVI). Also the Num Lock key(probably the others as well) doesn't respond. The keyboard doesn't light it up or anything. The PC seems to be running just as I left it.

    As far as I can tell, it happens after the screen turns off. My settings are 30 minutes in power management to turn off monitor, never sleep/hibernate, never turn of HDD, etc. Everything is double checked thoroughly.

    My system is as follows:

    i5 4670k with Hyper 212
    Maximus Vi Hero
    Sapphire Tri-X R9 290(latest beta driver 14.2 after using DDU)
    Samsung 840 EVO 250 GB
    Seagate Barracuda ST2000DM001 64MB 2TB
    8GB Vengeance Pro
    Cooler Master V550S 550W
    Windows 8.1 Pro 64-bit

    One strange thing I've also noticed, is when the PC goes past BIOS start-up, there is always this small white blinking "rectangle-shaped" dot up in the left corner of the screen. This is OK, because it's always been there for about 1 second before the Windows 8 logo shows up. However, around the time this issue started happening, the blinking dot keeps on blinking for a few seconds, and also changes location on the screen. I have recorded with my phone the boot-up and posted it on YouTube here:

    (sorry for poor quality)

    I was lucky this time as it went by rather quickly, but sometimes the duration is doubled. Mainly I just wanted you the get the idea of what I'm talking about.

    Does anyone have a reasonable answer to these issues?
  22. 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.

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


    OLD:
    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?


    OLDer:
    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.

    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.
  27. 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?
  29. I don't believe it's GPU related. I RMAd my card and it didn't fix a thing.
  30. 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.
