I have an Asus P4T533-C system that worked fine for years but is now
dead.

The problem started with a week of intermittent Windows XP freezes
that required hard reboots. Then I couldn't reboot at all, no video,
no BIOS beeps, nothing but my fans. And I got a Euro police car siren
sound.

I disassembled my system and got the alarm to go away by setting the
OVER_VOLT jumper to disabled. (I wasn't overclocking, but had that
jumper set so I could do so thru the BIOS if I wanted to).

I suspected a power supply problem, but two other power supplies
haven't fixed it.

The only other things I have left in my system now are the mobo,
memory, and CPU. Since I have 4 RDRAMs, I tried every combination of
just 2 that I could try, thinking maybe one was bad. And I did a
super-quick touch test with the heatsink/fan removed from my 2.26 Ghz
cpu to see if it was getting hot. It was, and I put the heatsink and
fan back on. I also tried clearing the CMOS, but that didn't help
either. Still no BIOS beeps, just the fans.

I'm thinking that something bad happened on the mobo and it's no good
anymore. If that's it, that's bad enough, but maybe I can find a
replacement on ebay and reuse my RDRAMs and cpu. Is it worth the
gamble? Or is it likely everything is fried? Are there any other
diagnostic steps I can try?
