Anyone visited any of the Nvidia forums to look into this? I had the exact same thing, HD access, white screen, then the HD stopped and the system was locked down completely. Only a reset/reboot got you going again.
I had the 21.83 and 21.85 drivers in place when I was having this problem. I finally just yanked the vid card (GF2 MX400 64mb), put my old Viper back in, and completely cleaned out my system, reinstalled Win98, reinstalled the Diamond drivers, and here I am.
Still can't play AH very long, FPS runs in the 40's for a while, then "if" I get into a fight, the FPS drops to single digits. If I can extricate myself and extend safely, the FPS come back up to the 40's. I am theorizing that DirectX 8.1 may be a bit picky or buggy with some mobo/vid card/CPU setups.
FWIW, I am surprised that the various manufacturers making the GF2 MX/MX400 series cards are not embroiled in lawsuits galore. I have not read of one happy owner yet, and I have been searching for answers to my own troubles and which led me to the various forums in the first place. GF2 MX owners are experiencing a a variety of similiar problems, which I personally would summarize as the cards are pieces of crap, sold with the "GeForce 2" title to attract buyers, who are then stuck with a card that does not work correctly, and they cannot return for a refund or get any customer satisfaction. Best Buy and VisionTek are two companies I am referring to, neither of which will get a penny of my business in the future.
