HI. I recently buy a geforce fx 5600, and ater installed it i experienced some problem. Installing driver provided with the graphic card, when try to open some 3d applications, monitor shut down and card has disabled. Installing driver provided by nvidia (52.16), the applications opened, but with serious display problems i.e. unreadable text, items with strange colors, disturbed 3D effects, etc... I tried to upgrade mainboard bios, but nothing changed. My system is: Athlon XP 2000+ MB K7S5A (29-02-2002 bios) 768 MB DDR RAM 20 GB HDD (system) + 120 GB HDD. Someone could help? Thanks.
