If the error is related to the drivers, it's possible they were never installed correctly or got corrupted somehow.
I say you update to the newest version of drivers for that card. You can download them from the ATI website (it'll say AMD all over it, but they're the same company). Browse here and select your o/s and download the driver. Un-install your old drivers, and install the new ones. You should be good to go hopefully
