Asus P4B266 won't boot

[Gato]

Hi,

I built a machine about 4 months ago (Asus P4B266, P4 1.8Ghz, 300 watt PS, 512MB). Everything was working smoothly until yesterday. It locked up while I was using it so I rebooted. Won't boot up at all now. When rebooting, the HD lit stays on, the CD-rom drives liight up as if they're being checked (but not the floppy), there is no video and doesn't post at all (no beeps either). Unplugged the hard drives and cd drive (IDE cables and power) but still have same problem. Tried a different video card (although only had PCI video card available). Unplugged some PCI cards. Tried unplugging ram. Tried reseting CMOS (unplugged power, removed battery and shorted the solder points to reset), still can't even get to CMOS. Didn't move or bump the machine. Was working flawlessly until now. Any ideas? Any help would be appreciated. Thanks.

Try plugging in speakers or head phones into the on board sound card and see if the motherboard will tell you whats wrong.

That was the nicest thing about this board. I believe a jumper on the motherboard has to be set on as well.

Thanks for the response.

I tried that (hooking up speakers to the line out and also tried setting it so the vocal post says anything through the internal speakers). No luck. I got a power supply tester and it test fine.

I'm thinking the motherboard may have died. If the CPU chip died then the motherboard would probably still alert me that the CPU failed through vocal post. But then maybe I'm wrong. Any more suggestions? Thanks
