I have a xtasy Radeon 9600 Graphics Accelerator 325 mhz vpu core, 256 ddr memory, 128-bit memory intereface, memory clock: 200mhz (400mhz ddr), dual 400mhz dacs System Requirements is P4/III, etc., with compatible Agp 4x (1.5v), 8x (0.8) or universal Agp 3.0 bus configuration (4x/8x), windows x, etc, 128 memory, 300 watt power supply My mainboard is a P4 Mainboard Model p4s5mg/gl+ with a 2x/4x Agp slot for 2.0 -compliant interface, P4 1.8, windows xp, 512 ddr memory, with 400 watts of power. I went through all the steps of disabling the onboard vga, making sure the card was snug into place, loaded the drivers, went into the bios and switch the primary graphics adapter from pci to agp and nothing. What am I missing? Do I have a bum card or worst mainboard. Should I be looking to switch some jumpers? or what. Or is the card not compatible. I am not seeing it. The system will not detect this card, what is going on.
