Did you fix your problem? CMOS battery removal is good. Id also try a different mouse and keyboard if you can to see if they also dont get recognized.

You've done good basic troubleshooting, so there's nothing obvious re the parts and their connections.

Is this a new PC, first time turning it on?
If it's an existing PC which suddenly failed, did you change anything—hardware mainly—shortly before?

Look around the motherboard with a flashlight. Do you see any capacitor tops bulging, or burn marks on the board's surface?

The removal of the CMOS Battery and replacing it worked ! Thanks for responding guys!
