Have you checked the suspected keyboard with the other computer? If not, try it.
Also, there could be an issue with your R.A.M. You should check that out. I'm not sure of the exact sites, but they are out there. There is a site where you can download software to check your RAM.
Have you checked your Device Manager to see if it displays any problems?
It could be the connection port itself that's bad. I had a client that had problems with the monitor. No monitor at all would come on, and after opening up the computer case and looking at the motherboard, I saw that the solder connection was disconnected from the motherboard. So, you may need to open up your case and see if it is loose anywhere.
Also, when you boot up, do you get any error beeps? If the keyboard is faulty, it normally would alarm the BIOS. If it doesn't do it, then you may have a bad connection somewhere.
While the computer is on, open NotePad, and try to type, and wiggle the wires at the same time. Also, go to where it connects to the port itself, and try slight turning/moving from there.
