Re: Mobo repair - any point?

<BertieBigBollox@xxxxxxxxx> put finger to keyboard and composed:

I've got a mobo where the led comes on when the power supply is
connected but powering on does absolutely nothing. I've even tried
shorting the power button pins to rule out power button problem but
still nothing.

Is it dead? Can I do anything with it or is it new mobo time?

When you say that "powering on does absolutely nothing", do you mean
that there is no sound from the power supply, eg no kick from the fan?

If so, then looking for problems in the CMOS RAM or flash BIOS EEPROM
would be pointless. Both these devices require a functional CPU to
read them.

AFAICT, you haven't proved that your PSU is good, so the first thing
I'd do is disconnect all its loads, connect a disposable load such an
old hard drive, and then short PS_ON (pin 14, green) to any ground pin
(black).
