Graphics card issues? Green lines and distortion on my screens

Posted on

Problem :

I turned on my computer this morning and it had a bunch of vertical green artefacts and some horizontal distortions on text.

You can see what it looks like

I assume it’s the graphics card but I’m unsure, I’ve removed all dust inside and replaced thermal compound on my gpu, I’ll replace the thermal compound on the cpu if anyone thinks it could be the cup.

The graphics card it’s an HIS AMD Radeon HD6850 which is a PCI-e 2.1 card with 1x DisplayPort, 1x HDMI, 2x DVI.

The rest of the computer is an ASUS P5Q-PRO motherboard with 8GB of Corsair DDR2 800mhz memory with an Intel Quad2Core Q9550 CPU.

I have 6 hard drives connected, 2 being SSDS and the power supply is a Corsair TX750W.

Does any one have any suggestions, ideas or thoughts.

I’ve had a look online and noticed “reflowing” graphics cards but don’t quite understand what to do. If the card is dead I might as well try it because on a bunch of websites they say that reflowing gpus can fix core failures or/and gpu memory failures.


Solution :

I replaced cards for a graphic artist a while back for a similar reason… Hers had black lines and distortion instead of green. That did solve it… A bad video cable can do things like that too. I would try that first.
