I am new to the forum would like to know if anyone can help me. I recently installed a geforce fx 5600 ultra. When installed the latest drivers for it windows will not boot up. It freezes at the boot screen or has weird splattered colors at teh boot screen. I tried previous versions of the drivers but it won't work. I was getting windows protection errors, but i reformatted my drive and reinstalled windows and the latest drivers for everything including my motherboard. I had the same problem with the ti 200 before I put this one in. The ti 200 ran fine after I installed the original drivers that came with the card which are way out of date, but none of the newer drivers would let windows boot. I have a Shuttle Ak31 board with all the latest drivers and 1gb of ram. I have a 250W psu which is the minimum for the 5600 ultra. I am running Win98SE. I don't know what the problem is. I am running memtest right now. I would appreciate if someone could help me. Thanks.
