Thanks for the info.
Hardware is compatible. PSU has sufficient AMPS on the 12V rails.
Have to start off simple.
Always unplug from the wall socket and take anti static measures when working on the PC. (TASM)
Check you have the following cable securely attached.
24 pin ATX power connector and the
8 pin 12V power connector (from the PSU to the Mobo).
The 2x3 pin (6 pin PCI-E plug from the PSU to the end of the GPU.
The CPU fan wire, (bared or broken) attached to the CPU fan header on the Mobo.
Unplug the monitor. Power up the computer and see if you can enter the BIOS.
If OK. Turn off, unplug, TASM, reconnect the monitor, restart the computer.
If OK, enter BIOS, set time, date, (region, language, if present) Save and exit BIOS, you are ready to go.
If the above is a failure, the most likely cause is a short under the Mobo, so,
Unplug, TASM, disconnect the monitor, remove the GPU, remove all other connections EXCEPT the CPU fan plug.
unscrew the Mobo and carefully remove it and place on a piece of cardboard larger than the board.
Your Mobo has six screw holes.
Look inside the case on the Mobo mount plate and locate the standoffs, ther must be six, (NO EXTRA ONES) and match the screw holes in the Mobo. Unscrew any extra ones or relcocate if necessary.
Also look for any dropped screws or pieces of wire.
