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
