The suggestions about cooling have merit, and it *might* be easy enough to aim a fan at your card to see if it helps. If your graphics card has its own fan, or cooling fins, it'd pay to check that they're in a good condition. I was given a card with a seized fan, and it runs fine for me, with a case fan blowing air across the cards heatsink (with its own seized fan removed). If anything, my jury-rigged solution cools the entire card better than the original fan that just barely cooled one small part of it. -- [tim@localhost ~]$ uname -rsvp Linux 3.8.4-102.fc17.x86_64 #1 SMP Sun Mar 24 13:09:09 UTC 2013 x86_64 All mail to my mailbox is automatically deleted, there is no point trying to privately email me, I will only read messages posted to the public lists.
