Need an expert's advice. I'm using the above graphics card and it first crashed while playing ModernWarfare2. Since then, it crashes even if I'm just browsing. A symptom that it will eventually crash is, when that mouse pointer seems to be enclosed in a box and the taskbar have areas where dots and lines appear.
I've tried updating the drivers/catalyst but the problem remained. Also tried lower versions of the driver. The only way the card works is if i use either a 1024x768 or 800x600 resolution.
