Question : Problem: PC hangs just before starting to load Windows 2000. PCI card problems

I bought a USB2 PCI card for my PC, which has an Abit KT7-RAID motherboard.
The system will not boot when I have both the network interface card AND the USB2 card connected, but will boot when either of them are present.
The point at which it hangs is after the memory check and disk detection phase, and  just before the initial Windows 2000 startup screen.

I've tried swapping the positions of the PCI cards, but I can't get the system to boot when both of these cards are present.

Could anyone advise on either the diagnostic procedure I should use, or possible causes for this problem, and how to resolve?

You may have an address or interrupt conflict, where both cards are trying to use the same address or IRQ.  When you are successful bringing up the system with each card, note what address and interrupt it uses (you can boot into the BIOS and it may show this).  If this is what is happening, you should check each card for a jumper that may allow a different setting.  If they don't have jumpers, using different slots can sometimes solve this, but since you tried that, look for settings in the BIOS that permit "legacy" devices and try enabling them.
