ATI Radeon 9800 Pro with 128 MBs RAM. Biostar M7NCG motherboard (NForce 2 chipset, DDR up to 333 MHz, AGP 8x). Screen garbage, character corruption immediately upon boot; sometimes plain, coloured after the card has warmed up. Initially the card would display garbage always, however, applying all the BIOS settings recommended, it now wouldn't display garbage when booting cold. BIOS settings: AGP 8x off. AGP fast writes off. RAM CAS latency set manually to 3. AGP voltage raised manually to 1.6 (garbage always if the voltage stayed at BIOS default of 1.5). AGP aperture of 128 MBs. AGP shares an IRQ with the USB controller (any way to dislodge it from there, BTW?). Any suggestions? Is there a stable BIOS revision perhaps?
