I've just had a PC in to repair from a client and on fully testing it I'm now sure the motherboard is faulty.
On switch on the system and CPU fans spin and you can hear the HD spinning up but the system doesn't beep or go to POST. Because it doesn't even beep or go to post it can't be the ram, cpu or any other components because it doesn't even reach the point where it tests for them. Therefore it can really only be the PSU, motherboard, or corrupt CMOS memory.
Clearing the CMOS memory didn't help, and testing the system with another working PSU gave exactly the same behaviour as the system's own PSU.. I also tested the PSU voltages and they all seemed fine on all rails of the PSU.
Also looking closely at the motherboard a couple of the capacitors look like they are leaking slightly out of the top which is never a good sign.
I spoke to the owner and told them the options. Source a replacement identical motherboard, a motherboard compatible with the existing CPU and ram, or get a new motherboard and CPU.
As the existing motherboard is no longer made I would have to find one on ebay. There is one but it has 4 days to go and already has 4 bids from different buyers so there is interest, so no guarantee I would win and it's already up to £20 which is expensive for quite an old second hand Athlon XP mobo.
Next for a new compatible motherboard, which is really the best option if I can get one. So does anyone know anywhere still selling new Athlon XP motherboards?
One other thing. With a Micro ATX motherboard fit in an ATX case? (same stand-off locations?) I've never tried fitting a Micro ATX mobo in an ATX case. Reason I ask is because I have found on ASRock Athlon XP motherboard that would be perfect but it is a Micro ATX size.
I basically need an Athlon XP compatible motherboard that can use DDR 333MHz ram and is priced under £40.
Failing that he has given be the go ahead to junk the current setup and stick a new motherboard/cpu in the system for around £60 which is possible, but I would need to use the existing ram to keep the costs down and that could be an issue with newer motherboards.
