Question about Biostar P4M80-M4 Motherboard
Thanks for info. However, I tried a good power supply but its the same problem. When I turn on power only fans (CPU and case - both plug directly to motherboard) spins. No other sounds. Also floppy drive light comes on immediately and stays on (and floppy cable is plugged correctly). I want to think it may be the motherboard or processor. Any other ideas?
Your CPU might be overheating, and the system is shutting down.
I just went thru this with my computer (same mobo).
No messages or beeps, just yellow light on front of case.
In my case the dust built up enough to hamper cooling.
Make sure you vacuum & blow out any dust inside.
Hope this helps.

Have you also tried different video cards? or the onboard built into your motherboard?

Unplug hard drive, no beeps? Unplug CD-ROM, no beeps? Remove RAM, no beeps? 85% it's the MOBO. Static, surge or just plain dead (and cheap).

I assume you have the fan of your power supply working indicating that power is OK.
Disconnect everything from the motherboard leaving only the processor, fan and power. If you don't hear any beep means that you have a problem with either the motherboard or the processor.
PS Verify compatibility of motherboard FSB and processor.
