Hello, recently I've encountered an issue I am so far unable to analyze and solve. Cca 4 days ago my computer started getting screen artifacts (various colour screen with vertical lines). While this occurs, computer freezes and needs to be force restarted. This seems to be occuring mostly when I play games (higher frequency of crashes) but even when I only have firefox up and for example watching youtube. The only clue I got so far was that sometimes the screen afrtifact lasts only for a few seconds and then the screen recovers with a message popping up, that Graphic driver crashed and was restarted. I've tried to reinstall and change all kinda of drivers (amd catalysts), also replugging the graphic card yet nothing helps. I even reinstalled whole windows, the problem still remains. I have the computer for about 3 months and never had any problems.

Can anyone maybe recognise these symptoms and give me some tips?
Here is my computer setup:

GPU: Sapphire R9 280X VAPOR-X 3GB GDDR5 OC
CPU: Intel Core i5-4670
RAM: Kingston HyperX NAVI edition 16GB (2x8GB) DDR3 1600
Motherboard: MSI Z87-G45 GAMING
PSU: Fortron AURUM S 600W

According to temperature measures, there shouldnt be any overheating and all the ventilators work fine. I am not sure where might the problem be or if it even is the GPU. I am just guessing.

In games its more likely to happen, the time to crash is much shorter. In games like Tera or CoD it usually takes 10-30 mins to crash, when i have just firefox on, it can take even a few hours (hadnt time to do enough testing for this)
