TY - very informative. My XP PS crapped out 10+ years ago and I replaced it with one from New Egg. Never had a problem. The pin thing did concern me since the plug into the motherboard has more pin than what the above pic show.
The more I look into it, the more I believe something when wonky with the bios. I am not skilled with doing things suggested. I have a PIII that ran ME in the closet. If I can get it to fire up I may just go stone age and use it for the couple programs that I can't get to work with Win11 (I get an error message that missing components - maybe a driver or a DLL) and when I tried to install on program the laptop wouldn't run so I has to use SecureKey to get it back and then use a restore point (whew).
I guess I can't say I didn't see this coming. I've backed up (zero data was lost

)and prepared as much as I could for the eventuality of having to give up XP. I wish I could buy a NOS XP or Win 7 machine.
