The Computer in subject: MSI Motherboard; AGP 4X 666Mhz PentiumIII Processor 758MB SDRAM 20GB HDD This computer currently has a nVidia TNT2 32MB AGP 2X or 4X not sure, and I just bought a ATi Asus A9250 (128MB, AGP 4X), whacked it in, and no visuals. I am currently guiding the computer on a horrible monitor card which is useful so I can actually see what I'm doing. I tried different drivers and everything, any suggestions? I'm considering the suspects to be a too weak power supply or maybe that the card says minimum requirement: 800Mhz Processor, but I don't think it could make that much of a difference. I doubt its a faulty card because XP detects it and tries to install drivers, but one driver wants me to insert a CD I don't have, and the other one says it can't install because "Access is denied". Its frustrating, this is the second card I've tried to buy for this computer that hasn't worked.. Please help.
