Hello,

 

I was using my computer the other day when randomly the screen flashed and froze black with dull vertical lines. I left the PC for 15 mins and nothing happened so I decided to restart it.

 

After the windows logo I get a permanent black screen.

 

Specs:

 

Intel i7-5820k @ 3.30 GHz

Sapphire HD 7850 2GB

Asrock Extreme3 X99 (socket 2011)

Thermal take Litepower 750W

Kingston 8GB - 1600

Samsung EVO 250 + 512 SSD

 

The problem started on windows 10, I have since tried a clean install of 10 & 7, no change except the computer force restarts after 10 seconds of black screen on windows 7 (after the logo still)

Installing the driver software causes the problem to start again from a fresh install, along with the automatic driver updates on windows 10.

I have tried multiple older version for my GPU driver and it's still the same.

 

I get small visual distortions all around the monitor without the GPU driver installed, coloured lines going up and down I can post an image if that would help.

Hoping this isn't a faulty GPU as I'm a poor uni student and the GPU is more than 2 years old.

 

Any help would be greatly appreciated

Still can't figure it out, tried installing on different ssd/hdd also

 

Should I just assume I need another GPU at this point?

Hello Cylace,

 

I get small visual distortions all around the monitor without the GPU driver installed, coloured lines going up and down 

 

 

Does the above mean that you can actually run the computer as long as you do not try installing any drivers specific to your HD 7850, if yes, try restarting in Safe Mode to see if the distortions are still the same.

 

Another test you may be able to do if you or someone close by has a notebook with an appropriate video port, try your video cable and screen hooked up to the notebook to see if the problem is replicated there, alternatively, test your PC with an alternative/appropriate screen

Thanks for your reply

 

That's correct, the computer runs but minor distortions are visible in safe mode or before drivers are installed. Turning off automatic driver installation on a fresh format of both W7 and W10 allows me to continue using the display, with the graphical distortions. As soon as I turn auto driver updates back on or install the drivers manually the computer black screens and I have to run in safemode to uninstall my 7850 graphics driver to remove the black screens.

 

I have tried my PC with multiple monitors/cords and it has the same black screen issues and visual distortions on all of them.

How to view all Windows 8.1 and Windows 10 applications, App Store applications, and third party applicaions installed on your computer.  This will not list Portable Applications.

Press the Windows key OS4o0pO.png and the R key to open the Run box.

When the Run box opens copy and paste shell:appsfolder, then click/tap on OK.

Suggests a hardware issue, either the GPU or PSU unfortunately  :(

 

Thermal take Litepower 750W

 

 

Not a good PSU when out of the box new, only produced 610W when tested, no efficiency rating, could potentially be up to six years old and so four years out of warranty, would suggest that if possible you swap in a known good adequately powered PSU for testing as a starting point, alternatively, have your card and/or PSU tested by a local tech or tech store that has the appropriate equipment for testing both under load.
