I suspect it to be Mobo related somehow i have cleaned the PC and to my eyes i can't se anything wrong, clean install and bios flash should have done something, so now I'm thinking hardware problem?

Thanks i looked true my old junk and i have usb for PCI, i found the problem and it's really a weird one, in he's PCI slot there is a wifi card i removed it, checked if the PC will take keyboards, and yes it will in all ports and any keyboard. Thanks for leading me to the solution.
