Hi,
The PC will post if it has been powered on for a time by pressing the reset button.

What is the fault when a PC POST from cold?
I have test swapped the power supply.
Removed and replaced the 2 ram chips individually in different order an just as single units.
CMOS voltage is within tolerance at 2.75 volts and has been swapped out for another with a similar voltage 2.8v.
No post beeps are heard when PC refuses to boot.
Any ideas people?
Thanks.

Motherboard ASRock K7VM2
2*DDR Dimm
Athlon Duron 2400+
Socket A(462)
OS XP SP3 (but not really relevant to this problem)

A board that old could have any number of issues. You're long overdue for an upgrade of the cpu/ram/board. You might find a used 462 board on your local craigslist or ebay if you can change it out yourself. Here's one example used: http://www.ascendtech.us/msi-ms-6390-socket-462-amd-mot....
