My keyboard stopped working some time ago.There was no error shown.When i open keyboard option in control panel then there are no drivers shown there like standard 102/102..etc. Similarly there is no keyboard entry in device manager.It sometimes work on restarting the machine but stops working after some minutes.Then when it was working on startup i installed new windows OS but the problem is still there.
NOTE:When i unplug and plug the keyboard back then the three lights blinks.It surely means there is no problem with hardware. What should i do?can anybody help me?
NOTE: Sorry ,i forgot it is an PS/2 keyboard

You cannot unplug a PS/2 keyboard and plug it in again and expect it to work without rebooting, unfortunately. The BIOS has to initialize it at boot-up time.
The fact that the lights blink means that the keyboard is getting power and is initializing. It doesn't necessarily mean that there is no hardware fault.
Try the keyboard in another computer, and try another keyboard in your computer.
You will probably find that your keyboard won't work in any computer, and someone else's keyboard will work perfectly in yours. Keyboards die - it's a fact of life.
Luckily they're pretty cheap, but do yourself a favor and don't buy the absolute cheapest. Try them out before you buy one - get a feel for the keystroke action, and choose one that feels right for you.
5There might be a problem in your registry which is caused by wrong values in the UpperFilters.
The problem could be for example that an additional keyboard driver file is defined but missing which causes the normal mouse/keyboard driver to fail.
