Could be a few things 1 dodgy graphics card as you thought, 2 A VIRUS scan you computer with a AV and Antisyware program for spyware. 3 SYSTEM TEMPERATURE (over heating) I see you have some case fans fitted so it might be your heatsinc full of dust and just needs a good clean out between the panels. 4 HARDWARE CLASH, a new piece of hardware you installed is not compatible with something else you have.(driver issue).
