Hello again!
I have a Razer gaming mouse, i think the name is Razer Taipan.
A logitech Keyboard, K740.

These are the only USB Stuff that i use all the time. The Mouse has a specific driver, but as i said, during one day everything was working fine and in the next day, i had this problem. I use both mouse and keyboard for quite some time now, they never caused me any trouble.

I just checked and the problem is still there u..u Thank you for the attention!
