Specs
OS: Windows 10 64 Bit
CPU: i5-4670K (Stock)
MOBO: EVGA Z87 FTW
GPU: Sapphire Tri-X R9 290 (Stock)
PSU: EVGA SuperNOVA 850 G2
 
The other week my computer started to act up. I'd be browsing the web and all of a sudden my screen would go black followed by my GPU's fans ramping up to full speed. Other times my screen would do this: http://i.imgur.com/GvWMbJZ.jpg 
 
I've tried re-seating my GPU and checked the PSU connectors, but have had no luck. Anyone have any idea what could be causing the issue?
 
Thanks!

    That looks like bad VRAM on one of your video boards.

    Could be a bad connection on the cable too, or just unplug the power to the monitor and plug it back in. That's happened to me before.

    Have you run CPUID HWMonitor to capture your system information?
    It is free software:  http://www.cpuid.com/softwares/hwmonitor.html
     
    Run CPUID and capture Min & Max  Volts and Temps
    +12 Volt rail should never go below 12.0 V - would indicate a PSU issue if not 12.0 or above - (if your power to PSU is good - use UPS to guarantee 120V).
     
    If the GPU is not over-temping it is probably VRAM on the videocard or the PSU if voltages are not stable.

    Your 850W PSU in theory is more than enough as the +12 rail is rated for 70.8 A
     
    Since your PSU is fully modular - try changing the VGA power cables, just to rule out the ones you were using had an issue.
     
    What kind of connection from GPU to Monitor?
    Confirm cable from GPU to Monitor connection is tight (if you have another cable replace existing one for test - long shot but hey if you have one)

    Monitor Cable: I'm currently connected to my monitor via DisplayPort. I unplugged it both from my monitor and GPU and re-plugged it back in. So we'll see if that does anything. My second monitor is connected via DVI-D. If the issue pops up again, I'll see what happens when using one monitor.
     
    VGA Power Cable: I'll give this a shot next if the above doesn't help. 
     
    HWMonitor: My min voltage is at 11.088 V and my max is at 11.176 V. Not sure if that's in the norm, the software being inaccurate, a BIOS setting I need to change, or a faulty PSU?

    Thanks everyone for the help thus far.

    Software is inaccurate. One software says my 12v is at 10.77v and the other says it's at 11.7v while a voltmeter says it is 12.2v at idle or under load.

    Alright cool. Phew.
     
    So quick update. When using just my primary monitor connected via DisplayPort, the black screen + gpu fans spinning at 100% issue occurred. I then unplugged my primary monitor and was using just my secondary monitor connected via DVI-D and issue happened there as well. 
     
    Going to try swapping out the power cable on the PSU to see if that does anything.

     As I had mentioned earlier, a screen like that usually means that the VRAM on the video board is defective. It is time to RMA your video board.

    I agree with Zuhl and Cool that it's more than likely failed VRAM/card..But before condemning it, I'd uninstall MSI Afterburner or similar utilities you might have..Then use Display Driver Uninstaller (DDU) to remove the AMD driver and any optional driver components using the Clean and restart (Highly Recommended) option in Safe Mode..Then install the latest AMD Catalyst Driver and hope for the best..If no joy, try the card in another system or take it to a PC repair shop for testing and see if it fails or not, if any of that is possible, and go from there..You could also downclock the VRAM or Core Clock with MSI Afterburner just for kicks to see if it makes any difference..Chances are good the card is bad and you'll need to RMA it.

    I had actually attempted to post a more detailed response and for more than an hour the website refused to respond to my request so I had to trim it down a bit. Nothing wrong with these forums though. An EVGA tech assured me that. Now I have to try and figure out what is wrong with this PC, my backup PC and laptop since I couldn't post from them either. (end of rant)
