So after the recent patch in WoW my video has been flakey at best. I've been getting problems where a random texture will extend all the way across the screen. I've also had problems where the UI in general will flicker.
I thought this was a WoW problem until sometimes the system will lock up. Then it acts as though it will shut down and no display is visible. Then it comes back up and the system starts running again.
This has also happened in Need for Speed Most Wanted so it's not a WoW issue.
I've updated most recent drivers (uninstalled, then reinstalled), I've updated the drivers on my motherboard, I've also done any microsoft updates thinking that would fix it. Still no luck.
I checked the temperature of my card using ATI's CCC and it's reading at about 62-64 degree C.
I have a Core 2 Duo e6300
Gigabyte DS3 965p
1 GB of PQI memory.
Running XP Pro.
