I am not sure it could be a computer issue... Between nvidia drivers and the computer itself...

It seems to happen randomly on computers.
My old computer that I do not use that often does not have the official nvidia drivers on it because all the new drivers after a certain revision would actually cause my computer to crash... Unfortunately the omega drivers website no longer updates so its no use to change anything. My old computer ran graal at full speed until v5 then it slowed down but I fixed that by adding in more ram. It only has 896 megs of ram however and it runs v5 with minimal slowdowns even with the fact that its barely holding together and will soon just probably burst into flame.

ok I just went on and on again...

what I usuallydo if the normal nvidia drivers are not working (causing lag/crashing and other such glitches when the last version I used worked fine) was look for other drivers or go back to the last working drivers.
Its could be a bad card or it might not (I have had my old nvidia card on my old pc actually burn up on the 1st day and had to return it)... also you could try to get a drivercleaner program to remove all the old drivers first... (nvidia driver cleaner on google seems to find some)

- removed site address... - theres free driver cleaners out their...
