My other comp is artifacting badly in 2d windows. I get random dots, then stripes, and other flashing artifacts randomly, but sometimes it doesn't happen. At first I suspected overheating but I tried it with the case cover off, checked the fan is spinning, but it was still artifacting. However, it doesn't always artifact, sometimes it can be hours before it starts artifacting but other times it artifacts on boot up. I've noticed that it hasn't artifacted in safe mode yet, wtf?
