Hope you can help.
I've a motherboard that seems dead. I've changed the processor, psu, memory for known working ones and disconnected all non essential peripherals (drives, USB connections).
The light on the motherboard comes on but non of the fans spin up. There are no bleep codes to help diagnose the issue. I've inspected the capacitors on the board to see if there's any obvious leakage or bulging but found no issues.
At what point in POST do the fans come on in your experience? Can I assume that if the fans don't spin then POST isn't even starting?
I should also add I've tested the on button to make sure it's resistance spikes on pressing and also swapped out the cmos battery and cleared the cmos.
One other thing to note is that the psu fan doesn't spin either.
Any feedback or ideas would be much appreciated.
Many thanks
Richard
