The card is an Abit Siluro Ti4200 128 MB AGP 8X.
For a while now I've been seeing odd symbols and characters on the boot screen and in the bios, in the last few weeks had trouble with graphics - ie huge spikes coming off 3d graphics, hard to explain, and in the last couple of days its actually caused my whole computer to reboot.
The fan on the card (see above) doesn't spin when I'm starting the computer - should it, or should it only spin when running games? The card itself gets VERY hot to the touch within a few minutes of turning the computer on - is there anything I can do?
edit: Just had a five minute go on Vice City and the fan didn't spin once - this is obviously my problem. Are these fans in any way user servicable/replacable?
