Computer wont POST

i have an old computer that wont POST or give a display.
ive tried two motherboards, two PSUs, and two processors with this same machine and not once have i got it to so much as POST, much less boot.
im at my wits end with this thing, what the fuck is up with it?

That computer is cursed
Cleanse it at a church

im beginning to think thats the case

someone please help

Try another display cable.

Dead hard drive

Does it have a pc speaker? Are there any beep codes?

already replaced the hard drive. nothing.
tried multiple cables and monitors
one of the motherboards doesnt have a speaker, but the other one did and it didnt even beep.

not your personal tech support
but its probably the memory
or you dun goof'd it

checked the memory, still no post or beep
