Ficle startup beep, not beeping often leads to no start up.

[TungFree]

If fan blows stronger, computer will not peep, nor start, and must be shut down different ways before restarting. Sometimes holding the start button down and restarting, but often that too fails. Sometimes shutting off power, but that too is a toss up of a coin. Sometimes will reset Bios cap and battery out/in for 15 minutes.

Only when fan bloes softly is the beep then heard and the computer starts right
Non of these will work every time though they all work some of the time.

I cleaned up the CPU fan and the case fans but no change, pulled out and reseated video card,
Pulled out and reseated the memory sticks,
Pulled out and reseated 12 volt plug to the motherboard.
Pulled out and reseated 24 pin to the motherboard.

Anyone had this and solved it?
Any Ideas?

As in most the fan slows when the BIOS passes POST and the temperature control kicks in. The beep is not issued because the BIOS POST test is failing somewhere the fan remains fast and the system doesn't boot.

Reset the BIOS to defaults and then run a memory test overnight. If the memory test doesn't reveal any problems strip it down to the basics CPU, GPU, 1 Stick of RAM and see if it will POST reliably. If so then add in components until you find the faulty device.
