Mouse and keyboard freeze together

My mouse and keyboard freeze together while working. I do work from home, and I thought that this could be of overheating. So, I kept seperate fan for cpu since we don’t have AC. It did not happen for some days. Again it is happening now even after providing cooling fan. Please, suggest me any quick ideas to resolve this immediately. Thanks in advance

Hello,

Welcome to Computer Forums :wave:

That does sound like an annoying problem!

To help narrow down what the issue might be would you be able to answer the following?

What sort of device are you using, is it a laptop or a desktop?

Is this is an issue that has developed recently?

Do the mouse and keyboard start responding again on their own or do you have to reboot the machine to be able to work again?
