Pc Turns on but no signal to monitor mouse or keyboard

Ok, really wierd, my desktop (dell inspiron) restarted for some reason, and when it rebooted, The keyboard and mouse were no longer connected. I am using a wireless mouse and keyboard, and the desktop does not have a PS2 for keyboard or mouse. I have taken the mouse and installed it fine on a laptop, so I know it is not batteries or hardware failure of the mouse or keyboard.

How can I Isolate the problem? I cannot get into bios as no keyboard response. It boots all the way into the security desktop, but I cannot log in as no keyboard response. All services still start, as it still hosts my intranet.

Thank you in advance for any direction or advisement.

Hello,
I tried everything you can think of! Turning it and leaving it, holding the power button, pressing buttons on the remote and the tv screen remains black! Idk how to fix this issue and apparently it seems no one else has any clue!

To help my sister who has a few keys not working on her keyboard (which are used in her password login), I was told to take the battery out and hold start for 30 seconds and then replace the battery. I was wondering what the pushing the start button does exactly before I do it?

my computer will turn on but the monitor, keyboard or mouse will not work. Also it beeps all the time it is on. Has been working fine until now. Any help is appreciated..
