I've been expiriencing a crash where my screen would show vertical lines usually when playing games. Sometiems they are red/orange and gray. I got a R9 270 2GB which is overclocked to 1050/1500. When i google 'vertical lines pc crash' every thread about that is with AMD cards , 90% time R9 Series. The thing is that sometiems it wont crash for months and then crashes few times a week. In other threads they usually say GPU is dying but i dont think its that because it cant be that alot of AMD cards are dying with the same crash. Could it be a driver related problem? Temperatures are completely fine, doesnt go above 75 in demanding games.
