I recentlty installed windows 2000pro on a amd 500 computer. The motherboard is an fic 503a motherboard with pc133 memory. I have 384 meg worth. The video card is an ATI Radeon DDR 64meg VIVO card. Win2k runs for about 5 minutes and then locks up. Sometimes it the screen goes black and is frozen. Is my memory bad or the video drivers? My hard drive is a 20 gig maxtor UDMA 66. The memory was recently purchased.
