Ok, it was running great, i was testing out my new wc system. I restarted, and nothing happened. I tried another processor, nuthing. I tried new rem, nuthing. Its not the video card, and i rtied unpluging everything but the power to the mobo, and still no boot. When it firt stopped booting, i saw i had left off the chipset heatsink. Its a 333fsb chipset, but only running at 266, and when it touched it right before i put it back on, it was very warm, but not hot. I have a sinking feeling i killed my mobo, but i hope it could be somthing else. Ohh, and i tried taking all pci devices out and clearing cmos and lots of other stuff.
