There are those who believe that ATI’s Catalyst 3.8 drivers are blowing up their equipment.
Here’s some threads from various forums on the subject:
If you’ve been affected by this, write them here
If you haven’t upgraded to 3.8, don’t.
If you have, then uninstall the drivers and go to 3.7 pronto.
There’s been some rather interesting explanations as to why this might be happening, but for now, the only prudent thing to do is to remove any possibility of damaging your system.
After all, it’s just a set of drivers. It’s not like using Catalyst drivers save lives or anything. Using 3.7s instead won’t kill anybody, not even ATI.
You lose very, very little if you play it safe, even if this proves to be a case of mass hysteria. On the other hand, if there is something to this, and you don’t, you might lose your monitor and/or video card.
