• Have you tried using a different keyboard and mouse? If yes, how was it?
• Have you tried using your keyboard and mouse to another computer? If yes, what is the result?
• To make sure that we have not missed on anything, what troubleshooting steps have you done so far?

As an initial troubleshooting, we suggest that you try updating your keyboard and mouse drivers to resolve the issue. You may also check and follow the troubleshooting steps in this

Computer powers on, but monitors, keyboard and mouse don't work (windows 11)

Hi,

I recently purchased a windows 11 PC and it has been working fine for about a month. I went to turn it on this morning and there was no response from my monitor(s), keyboard or mouse. So far I have tried the following:

1. Restarting the computer
   
2. Unplugging all the equipment then plugging it back into the computer.
   
3. Reducing the monitor count from 2 to 1
   
4. Moving the HDMI cable from the video card input to the motherboard input
   
5. After shutting down the computer, unplugging it from the wall for 30 minutes to reset the power
   
6. Tried to turn on the computer in safemode using Microsoft's suggested method for black/blank screens at there website. Start your PC in safe mode in Windows - Microsoft Support
   

So far still no response. Anything else I can try to get the computer functioning again?
