Hi there! I recently noticed some fast horizontally lines flickering for 1 to 2 seconds on my screen.I can't call them artifacts but they are some kind of lines that appear and disappear all over my screen (in game and on desktop too) when I scan my gpu with MSI kombustor artifact scanner I can see them too flickering for 1 to 2 seconds on my screen but kombustor doesn't detect them as artifacts.This issue happens like 1 or 2 times in an hour.I have a palit geforce gtx 770 OC and I am using a dvi to VGA adapter to an old lg 1360x760 monitor.Is the card dying or this is just something I should not worry about?
