Weird green columns on screen

Apr 24, 2018 11:58PM PDT

Computer crashed while gpu was under heavy load. Now I got green stuff on my screen, even outside the os. I could only load win10 in safe mode, until I used ddu.

Now im stuck with microsoft basic display driver, occasional black screens and green columns on screen. (No bsod's) Trying to update my driver gives black screen, after which i have to hard reset the pc. Using the built in graphics I seem to not have any problems.

At this point i was sure my vram was failing, but while examining the insides, I noticed that the cpu fan had come loose! After reattaching I ran some tests to not find anything wrong with the cpu.

Should I now replace just my gpu, or should i get new cpu / mobo / psu?

I'd start with a new videocard. That should be all.

It does look like a typical video card failure.

Those R9's were known to need work in the GPU heatsink and fan to avoid problems like this. Did you try canned air to the (powered off) machine and card? Did you have your tech or yourself try new heatsink compound on the GPU? There are videos on YouTube on this work.

I tried cleaning and dusting. Also reapplied compound. Seems to be permanent damage. Thermal pads only covered some of the vram and there was some dust build up. Could be related to that. I ordered a new card now.
