3 GHz cpu, 2GB ram.
I have tested the cpu in another m"board and it works okay.
I have tried replacing the ram, trying another PSU.
I am thinking the M'board is shot, but i have a mate with 2 ASUS P4S800-MX boards and he has the same problem. Coincidence or what?

Re: PC wont boot, not even to bios
Maybe the mobo is shot for u and he has his PSU shot.......Check for any burnt smells from the mobo. See if the cable from the PSU is properly connected to the mobo. Try removing all drives like graphics cards, RAMS one by one and see if it works.

The BIOS utility probably has a setting for the BIOS to automatically detect and maintain your CPU's clock speed. Make sure that is ON or ENABLED. Another probable reason for the failure may be your RAM settings. Again, use the automatic detection of your memory's speed and latency settings.
One last probable reason may that you may be using different kinds of memory SIMMS or DIMMS. Some boards are very finicky and will not work efficiently with different types, if at all. Others will simply not work.
Remove the BIOS recovery jumper near the battery on the motherboard and attempt to boot. If the system displays a startup screen, replace the jumper on pins 1 and 2 (pin 1 will have an arrow by it) and configure your bios appropriately.
You should only hear 1 beep. That 1 beep is power on self test, known as P.O.S.T. That loud flat line sound (And I'm pretty sure about this), was you're CPU. Just because you ran & passed the stressed test is nothing compared to running the system under load? That's why when you put in you other memory nothing changed. If you hadn’t mentioned you clocked up the FSB I would have come to the same conclusion hearing the loud flat line statement. Can you test the CPU in another board? That is about the only way to be sure it's not the CPU. Memory does not make that kind of sound. Memory makes short & long beeps. You can try clearing the cmos/bios by going to pg. 2-18 in you're user manual. This will reset the bios back to default settings & cross you're fingers!
If I can be of more service, just post back & let me know how thing go.
