Hey guys, I have a problem with my gpu, when I turn on my pc, the gpu flashes 3 redlights for like 1 second and then the lights dissapear, the pc boots, I can go to youtube and facebook and stuff like that with no problems but after 2 or 3 minutes of gaming the screen starts having black and white stripes blue dots. So I decided to change the thermal paste but it didnt work... it is still the same. I have had this card for 3 years and I game alot, in those years I have never changed the thermal paste (dumb) btw my PSU its a Corsair 650W TX V2... Is the gpu burned and dead? or is it a problem with the MOBO???
PS: which gpu do you guys recommend between these 2? MSI hd 7850 twin frozr oc 2gb or MSI geforce gtx 660 2GB twin frozr oc?
