Well, I finally got a new mobo/cpu, but something's wrong. I upgraded to a venice core 3000+ on the Asrock dual board and put in a FSP 300W ATX 2.0 PSU. Original components include 2 Crucial 266MHz 256MB Dimms, a Radeon 8500 AGP card, a Soundblaster Audigy 2 card, a Linksys NIC (don't ask why, but it has to be there), 2 PATA hard drives (Samsung 80GB, Maxtor 40GB), a lite-on CD-RW/DVD-ROM, and a BenQ DVD+-RW. It's in a Lian-Li PC-66 case. Oh, and I'm using the retail HSF. The BIOS works alright, but windows won't boot. I'm typing this at work, and I'll probably start by formatting the system HDD and re-installing windows, but I'm nervous. How can I reliably determine if any of the new components are faulty? I've built computers before, but I've been lucky. Any suggestions would be greatly appreciated.
