I thought I had done well installing a Belkin USB 2.0 and Firewire card, my first ever hardware installation. After a few initial problems I am now left with a PC that won't start up other than in safe mode. However, if I then disable the Standard Enhanced USB I can start up OK. If I then enable the Standard Enhanced USB it all works fine until I shut down and try to restart again. I notice that it shares an IRQ with NVIDIA GeForce 3. I thought about changing theIRQ settings but not sure if this is the answer and feeling I'd be going in above my head. Any suggestions??
