Some solutions to this unusual problem would be greatly appreciated. I know USB ports can be a bit temperental but not known ps2 before. The keyboard I know is fine it works on other pc was until this morning when out of blue it does not now. Checked on back of pc the ps2 socket seems fine not loose… what are things could I try/check to see if I can get it back working?

Have you checked the pins on the ps2 adapter on the keyboard cable one might be bent.

Go to Cntrl Panel /Keyboard /Hardware, is the keyboard a standard 101/102 ???
If that's OK, click on "Troubleshoot" underneath.

Possible you have an open circuit on one of the conductors in the flexible connecting cable. A simple ohmeter test would show this up

I suppose you have already tried re-booting.

PS/2 ports are sensitive to being "hot plugged" and there is a small fuse on their power line which will blow at the slightest provocation.

Unfortunately, this fuse is on the motherboard and difficult/impossible to repair.

Try Removing the keyboard in Device manager and rebooting; Windows should Find New Hardware.

I had this once a cheap Motherboard from new did not last long, it lost 5 volts supply to keyboard PS2 connection some where on the Mobo I ran a jumper wire across from the ATX socket 5volts line to get it working
