Is the keyboard usb or ps2?
If its usb then try another port. If its ps2(Green) then power down the
pc by holding in the power button for 8 to 10 seconds. Pull the plug and make sure no pins are bent. Plug it back in and boot back up. This should fix the problem if its ps2.
That is a circuitry problem. You can try this following procedure if you can.
--unscrew and open your mouse casing.
--you need a tester (VOM) to test the wiring continuity. If one of the wire is open connection you can replace it with a new USB or PS2 connector. If all the wire is shorted, proceed to the next step.
--Check if the microswitch is ok by testing the pin connection using the tester. Microswich has 3 pins, test only the soldered pins. When you press the switch, it might be shorted. If not, replace it with a new microswitch.
Microswitch and USB/PS2 connector are available in all electronics shops.
Check that it is indeed plugged into the purple PS2 port on your computer, if the keyboard is USB then try alternating ports. Some-times just by plugging it into another USB port it can work.
Also it maybe that the keyboard has died, try a friends keyboard on your computer to test it. Try do as much as possible before purchasing replacement parts.
You can try tighten up the cable behind the monitor or disconnect the cables and reconnect. You can try another monitor to see whether the mother board and the cable works. Some settings in BIOS may be changed to use on-board video card (the one embeded on the mother board, which is connected on the ports out of the card slots) on your computer so make sure it is using the graphic card that is connected to the monitor. For keyboard, if may be mechanic issue on port or keys or cables if you will not see anything wrong about the keyboard. You can try to use another USB port if it is an USB keyboard or use a USB/PS2 converter if the PS2 keyboard port is not working. If it is a PS2 keyboard, you can check whether the pins are bent and reconnect it. Sometimes that helps. If it is a wireless keyboard, then you will need to fix the monitor and then maybe fix the driver and stuff. You can remove all objects beneath the keys by putting it upside down and shake it or use a blower.
First, I would try booting to Safe Mode and see if that gets you to Windows. If it does, then it's a driver issue that can be relatively easily fixed by "Uninstalling" the keyboard in the Control Panel/Device Manager, then rebooting and letting the system reinstall the driver.
If that doesn't do it, then it sounds like the (assuming you're using a PS2 keyboard) PS2 keyboard plug port may be compromised (ie., damaged). Try using a USB keyboard instead and see if that solves your issue (as trying to repair a PS2 keyboard port is not practical).
Unfortunately there is no color code for the cables in the PS2 connector. All the details that I can give you is that if this is the PS2
The pin #1 moves DATA. The pin #2 is not connected or DATA2 (usually not connected) The pin #3 is GND The pin #4 is VCC for power (+5 VDC) The pin #5 is CLK for Clock The pin #6 is not connected or CLK2 (Usually not connected)
In case of a problem or clarification, don't hesitate to post me a reply before rejecting my answer. If you are satisfied, accept my solution.
