Try removing all Hardware that is not needed to start the comp including remove power plugs from all drives to see if it will go to BIOS. Remove PCI modem and any other cards not needed. Then if it goes. Add one at a time Starting with Hard Drive
of course start from scratch but leave 1 stick of memory in.so if i still get the same bleep when i strip it down,then it can only be the cpu or mobo am i correct?if so do i have to replace both cpu and mobo?if so whitch first?
