Don't have 3dmark06, can you point me to it please.
Yeah I've downloaded new drivers.
My cpu's temp is constantly below 30 degrees C.
I did a virus scan yesterday to no avail.
And there doesn't appear to be anything eating up my system resources.
In reply to the question about games, I have call of duty 4 which has had its performance halved since about a week ago, left 4 dead, which i can't seem to run on any settings without a ridiculously low fps, crysis I haven't checked, doom 3 seems to be terribly laggy and css gets about 30 fps.
