Vista - How do I fix problem with no mouse or keyboard?

I need some help! I can't get my mouse or my keyboard to work (in any way, including function keys during bootup) I have tried other keyboards and a mouse and the problem is clearly with the computer. I'm guessing one of my four kids erased the driver software, but I don't know how to do a system recovery or download new drivers, or anything else when I have no keyboard and no mouse function to allow me to control the computer. I need this computer to do a grad school assignment and am desperate for some help. THanks!

Hello ssmr,
Try and unplug the keyboard and mouse and then reboot, plug them back in, put them in different usb sockets and if necessary reboot, your system should load new drivers when you reboot.

is your mouse and keyboard USB? is USB keyboard support enabled in bios? (not that you can enable it anyway with no keyboard )

if thats the case buying a cheap PS2 keyboard will get you out the mire

yuo might also wanna check that your usb ports aint been disabled in bios or in device manager (with a ps2 keyboard )

you dont need drivers on your os for basic keyboard usage btw
