Hi,

are you using an old PC case with a new mobo? I had to cut the plastic
plug of my old PC case's front panel and then to plug the cables in
another order on a new mobo's front panel connectors.

And again, what does the POST say?

Later BIOSes used a sequence of beeps from the motherboard-attached PC
speaker (if present and working) to signal error codes. Some vendors
developed proprietary variants or enhancements, such as MSI's
D-Bracket. POST beep codes vary from manufacturer to manufacturer.

Information on numeric and beep codes is available from manufacturers
of BIOSes and motherboards. There are websites which collect codes for
many BIOSes.
