Mouse not detected

Hello Friends
My PC is not detecting any type of mouse(seriel and ps/2 both).While starting it gives messege that ps/2 mouse can not be detected, you can safey use seriel mouse.but Seriel Mouse is not detected even.Solution needed..Please

A serial mouse, sounds like you machine pre-dates Christmas ! :?

Since I don't know your OS, or system, here's an old article that might help :

It basically talks about IRQ assignments for various ports, which may conflict if not set up correctly. This may get your PS/2 mouse a life. It's a long shot, and for the life of me, I can barely remember using a serial mouse, even a PS/2 is starting to stretch it a bit.
