Hello there! Yesterday I bought a new PC (custom made) and booted it up and started downloading the usual stuff, drivers, video games and everything I needed. Everything but my graphic card is new the Graphics card was bought on craiglist (the guy just tested it to see if it works). But after a while this started to appear. http://imgur.com/a/FPaMG I already reinstalled the drivers and I didn't see it for a while, but it happened again. Could this maybe a software problems? Should I reinstall Windows before doing anything such as trying to return the card? The card performs perfectly, running WoW on ultra without issue.
