Motherboard Problem

Hi all,

I have a PC that makes a high pitched whistling tone when it's powered up.
No other output at all - no post beeps, no display no nothing. It is a tone,
i.e. it's coming from the PC speaker, rather than being a whining fan or
drive.

I've stripped the machine down to just the mobo & processor and still get
the noise. I have tried changing the PSU & the BIOS battery - no joy. The
mobo is an Iwill XA100 plus.

Any ideas?

Thanks in advance.

Disconnect the reset switch. If that doesn't work, pull the board and
test it sitting on cardboard or something that won't conduct
electricity. If that doesn't help, buy a new board.

I had a similar experience... as it turned out, it was the CPU which
had loosened from its slot (PII in SECC2).
