I have a mac pro 2008, and the graphics card (nvidia 8800GT) has started to lock up - I can still move the mouse but cannot do anything in Windows 7 (I hardly use OSX latelly so dont know if it happens there). The entire screen goes all garbled (various colours, flashing) and I have to reboot the machine.
The latest nvidia drivers for windows 7 have been installed, and until now everything has been rock solid.
Does this sound like the graphics card is failing? Or do I just need to tweak the cooling / fan speed on the card itself?
If I do need to replace the card, can anyone recommend a decent replacement that would handle most current-gen PC games?
