MOUSE AND KEYBOARD DONT WORK
Hello everyone,
I urgently need help.
Yesterday my desktop PC installed a Windows update. Since then, the PC starts normally up to the Windows login screen, but my mouse and keyboard don't work at all anymore. I can't even enter my password.
I have already tested the following:
* Multiple USB ports (front and back on the motherboard)
* Mouse and keyboard unplugged and plugged back in several times
* PC completely switched off and disconnected from power
It is striking that the LEDs of the mouse and keyboard only light up for about a second when plugged in and then go out again. The same thing happens with my controller.
The PC itself runs normally (fan and lighting work), and I get a picture until the Windows login.
Does anyone have any idea why this could be or how I can fix it? Is it possibly the Windows update's fault or rather a BIOS/mainboard problem?
Thank you for any help!
