Can anyone shed some light please? I was recently playing Shadows of Mordor about two hours and I went to a menu screen and came back and the frame rate dropped severly. I quit the game and went back in with everything fine again. Then a bit later I used the desktop for general browsing when intermittently the screen went all fuzzy and coloured - no distinct patterns like I would normally expect from a graphic card issue. It then reverted back to being OK. Then again it did it and this time it stayed that way until I did a warm reset and the BIOS kicked in. I went back to usual defaults and went back into windows. I've been overclocking my GPU to 1050 mhz and memory to 1225mhz with maximum GPU temp of below 70 degrees. I also run a small second monitor however this remained OK while my main screen corrupted. I'm currently in 30 minutes since I reset and there's been no recurrence. I even ran furmark in the background but no artefacts etc. I wouldn't have thought my overclock of the card would be of any concern in desktop as the card usually drops in speed. Anyone else have this kind of thing happen before?
