Just got my Hercules Radeon 9500 Pro, but after installing it my PC won't boot. Every second time I boot, I get the BIOS setup, which displays fine. Every other time, I get nothing on the screen at all. I am running Windows XP Pro with an ASUS CUBX motherboard and Zalman 300W power supply.


I uninstalled the drivers for my Radeon 7200, shut down the PC, removed the 7200 card from my 2X AGP slot, inserted the 9500 Pro into the same slot, connected the cable from the power supply to the 9500 Pro, and then turned the PC back on.


Any ideas? Obviously the card works to some extent, since the BIOS setup displays fine, but I can't get any further than that. I checked, and my PC should meet all of the system requirements for the card (ie AGP 2X, 128Mb RAM, 300W PS).

Make sure the card is completely seated. An unseated AGP card does prevent booting. Also, make sure the card voltage is supported by your Mobo. I know that some mobos (mine) only support 1.5v 4x cards.

Hope that helps

Hi,

did you connect the external power supply to the 9500 Pro? If you do not connect extra power the card do not work.

Good luck

Solved it - it was actually the bus speed. Like almost everyone else, I run my CUBX at 133/33. My Radeon 7200 worked fine at this frequency, but it seems the 9500 Pro can't handle it (or at least my sample can't). When I throttled it back to 100/33, the card works fine, but that reduces my CPU from 800MHz to 600MHz. That doesn't bother me too much since I'm planning on buying a new CPU + Mobo in the near future anyway, but has anyone else been able to run there 9500 Pro with a 440BX chipset at 133/33?
