Many Windows users have recently reported a problem with their keyboard. What happens is that their left Control-C command does not work properly – they cannot copy text after pressing the Ctrl and C keys on their keyboard.

If you also have this problem, you are probably very frustrated. But don’t worry about it. We have gathered some suggestions to help you solve your problem.

Restart your computer

The first thing you should try to solve the problem with Ctrl+C does not work is to restart your computer. Normally, a simple restart should solve the problem. But if not, there are other things you can try.

Physical deletion of the CMOS cache

Another way for users to reset their BIOS defaults is to manually reset a jumper on the motherboard. When I started working as a system administrator in a local high school, the students entered the BIOS and set a password to exclude other students. Resetting the jumper on the motherboard and using a default BIOS password to access the prevented access fixes this problem.

Before you start, make sure your computer is turned off, the power cord is disconnected, and then wait about 30 minutes for your system to cool down. Reason why? There may also be some electrical charge when you turn off and unplug the unit. You do not want to run the risk of electric shock or damage to components.

Keep opening the CPU and look for a small jumper – there may be two: one to reset the BIOS and one to reset the BIOS password. Remove both, reconnect the music center, start the system, and wait about 10 minutes. Once your BIOS is reset, reconnect the jumpers, then connect the system unit, reconnect the external devices and turn on the system.

On my HP desktop, the CMOS jumper is actually a button that I simply press for about 5 seconds. This process therefore varies depending on the make and model of your computer.

Try resetting the BIOS to the default settings.

Reinstalling HID drivers
