Hi guys. I have an annoying problem. When I play games like GTA V, Dying Light etc. there are horizontal stripes running vertically on my screen. IDK what is it but it sucks a lot. My specs are: R9 280X, i5-4590, 8GB RAM, 550 W Corsair PSU. I think that there were no stripes on my older 450W PSU so can this 550W Corsair cause problems with R9 280X? Thanks for every answer and apologize my bad english

Not sure if to congratulate you or ask you to let an electrician take a look at wirings in your home

Do consider using a surge protector

I didn´t overclock. To be clear, I even tried to downclock the card to 950MHz on core and 1350MHz on memory but didn´t help. Cables are completely fine, no twisting at all. And its plugged all the way into the card.

Driver: Crimson 16.9.2 - the newest one
Temperatures: Usually below 66 degrees Celsius during gaming. Thats cool enough,right?

Looks a bit better to me, but not too much, stripes are still there. Anyway, thanks for helping
