Ive recently had my dell upgraded with a Geforce 4 graphics card. The card works very well with all my games and seemed fine. After playing on my games for over an hour or so, I came back to my computer with a blue screen with alot of white writing. One of the main things I picked out were the words "DRIVER_IQS_less_or equal" or something along those lines. This has happened three times now and I would be very greatful if there is anybody out there who can solve it.
