|If you get no display even during bios bootup then the problem is nothing to do with 32bit windows. The card itself does not require a separate 12V power connection so you are left with a number of possibilities.|
1. The card is DOA out of the box. Unlikely but possible. I've had one.
2. The PCIe slot on the motherboard has failed.
3. Some other component including powersupply, CPU, Drives or RAM has failed.
Does your motherboard have an inbuilt graphics adapter as well as the PCIe slot?
If you leave out the graphics card completely and attempt to boot the board, do you get any BIOS beeps?
