Solved No keyboard working - new PC

So - I just got this gaming PC yesterday, as an upgrade to my previous Win 10 build. I have 2 SATA drives which I moved across and then changed the drive letters to those previous to keep things in order or soI thought. No idea whether that was what started the problem as I was also busy installing all my software but at some point I found the keyboard suddenly had stopped working. I looked online via my laptop & then worked through all the suggested fixes to no avail. I've tried 2 different KBs - my standard is an MS Natural Keyboard Pro & then also tried a wireless styletech one. They are recognised by the system both in the tone on connection, and then also showing up in System as working, yet pressing keys achieves nothing I've done both col & warm boots, updated Windows and ran Glary Utils but still no joy.

Some mouse actions seem equally affected e.g. right click for some actions, and in Edge I can't even access sites by clicking on links But just discovered the media buttons work oddly but that's it!

Totally stumped as I've never encountered this type of problem before so hoping someone here might have some insight.

Does the keyboard work to enter the firmware menu, pre Windows boot? If yes, see if you can get into safe mode. It's likely some 3rd party app/service causing the issue, but obviously pretty hard to troubleshoot with no keyboard.

If no have you tried a different port (if this is a desktop), do you have USB ports attached to different headers you ca try?

Also: You could probably use the Windows on-screen keyboard whilst you troubleshoot.
What is in your startup items?

Welcome to the forum, T.

Thanks for the suggestions - so yes, i've tried it in 4 USB slots and now just done the safe mode/startup checks but it isn't working even there It did actually start working again last night but I hadn't done anything to my knowledge that fixed it.

And thar's more annoying that after a reboot it's gone off again.

Oh & I can't find the OSK in mine - Accessibility/Keyboard only has 3 options & none are to use an OSK -

Got it sorted - turns out to be a USB issue in the end. Althought I had tried other ports they were all 3.0 and it was only when I put it in a 2.0 that it finally worked. So now I have to go & get a new KB into the bargain as I prefer my ergonomic split style over the gaming one I'm now using. But thanks for helping out regardless.
