So I updated my video card driver and now the keyboard and mouse don't work when I load up Windows login screen.

At least thats what I think happened. Just rounding up backup of my HD now, then I'm going to try to rollback the driver somehow and/or update the chipset drivers.

The thing is I can't control the PC in any way as the usb ports don't work and neither does the ps/2 port. And I *think* the network port is also dead because I have tried using remote desktop to no avail.

Plan now is to tcpdump on my laptop with a patch cable into the affected PC to see if there is any network activity so that I can maybe get the IP and connect using remote desktop. If that doesn't work, and I'm prety certain it won't - what are my options?
