So my windows 7 computer was working fine yesterday. But today it wont let me login. When i turn in the computer, it shows me the welcome screen, press esc key for startup menu. After that, it stays frozen. its stuck. And when i try to press esc or other commands, it won't work. the keyboard won't function. Can someone please tell me the solution? I even bought a windows 7 recovery dvd and it doesn't boot from it. And when i take the keyboard plug out, it shows me a screen that says keyboard error. Can someone tell me how to fix this? Thank you.
