Have them checked by a local technician to avoid further damage.

Try booting your system from a LIVE cd like linux, a verson of Hiren's tools, or the UBCD (ultimate boot disc for windows). If your keyboard still freezes with the alternate OS, you may have a hardware malfunction.

Hello, if your keyboard has malfunctioned the only way to type the password would be by using another computer in your home network to connect remotely to the computer to type in the password. If you need assistance with that let me know.

Thanks

find out if the keyboard are malfunction...

The usb ports might me malfunctioning . Try to use different ports. If that doesnt solve it then there might be a power issue on the board.

Are you saying it will stay on even if you press NumLock to turn it off? That's weird. But on most computers NumLock automatically comes on ...you can change this in the computers BIOS. Try pressing F1 as your computer is booting up to change this option.

check out this will solve your problem.
