#hardware #computer my aging respectable desktop Is hanging during firmware init. It doesn’t respond to the keyboard and it’s not possible to boot to alternate media.. I really don’t want to buy a new pc this year, does anybody have suggestions on what h/w or S/w issues might cause this?

Numlock on keyboard toggles light but that’s about it.

Memtest86 has come up clean in the recent past. Disks are fine. Video card is ok too I swapped all these for spare components.
