Windows 7: PS2 Keyboard - works on one PC, not on the other

I have seen a suggestion that changing certain registry values should fix this.. but the values are identical in both PCs. There must be some setting that differs between the two PCs that means PS2 works differently in Windows.. anyone know what it might be?
(PS2 showed its worth the other day, when one PC got stuck waking from hibernation - the options, discard or re-use the hibernation data, needed a keyboard input to choose, but all USB had stopped working. Luckily, a spare PS2 keyboard, and of course the fact that my PC had a PS2 port, saved the day!).
Thanks.
Two things: One....NEVER, but NEVER plug in any PS2 device while the system is powered ON. Bad things can happen if you do. I know it's sometimes tempting, but just DON'T do it!

Two.... on some PC's the PS2 port is set back inside the PC's just a few thousandths of an inch making it hard to get the PS2 plug in far enough to make a good connection. In those cases, I've had to cut back on the rubber coating on the PS2 plug, like maybe 1/16th of an inch, so that it can be inserted deeper into the PC. That's always worked for me.

Good Luck, Mate!

TM, if anyone knows the answer to this question, you do: Do you have any idea where I can get a PCI Express (or other modern) card which provides two TRUE PS/2 ports? (Not USB-to-PS/2). I was able to find a PCI card like that; but unfortunately, it's very hard to get a computer these days with PCI slots. (Mine doesn't have any PCI slots.)

I have that card. The problem is, it is PCI, not PCI Express. My computer has no PCI slots in it.

BINGO! I think I found the answer!

This card plugs into a PCI Express slot and provides a PCI slot:

This will allow me to add PS/2 ports to my new Dell computer.

I have one also. The problem is, I have had USB fail twice in my life on two separate computers, which eliminated the USB mouse and keyboard. If USB fails, my USB to PS2 adapter won't work.

On both of those computers, I had PS/2 ports, so I was able to easily fix the USB problem by connecting a PS/2 keyboard and mouse.

I understand your concern but what I have is an additional USB option by use of both a 3 additional ports on a front media card input panel, I also have a secondary USB3 card at the rear of the case. When checking the system I disconnected the various options in turn and could always run a USB device via another port.
I also have Bluetooth available and several BT mice and keyboards as a secondary backup
