Client has fairly new HP Envy tower running Windows 10. Working fine until earlier today. In the middle of using it, USB Keyboard and Mouse stopped responding. Both work at BIOS (entering setup with ESC). I can run keyboard and mouse diags from the BIOS, both pass. USB diags pass from the BIOS. Overall system test passes.
But as soon as I start to boot, nothing.
I can get into Safe Mode, but no keyboard or mouse there either.
I powered down, unplugged, pressed the power button for about 30 secs, left it unplugged for a while, tried different keyboard/mouse/usb ports... no joy. It gets to the Windows login screen but can't get ctrl/alt/del to be recognized. There are no "traditional" mouse/keyboard ports to try... just USB.
I was able to get into the "fix my computer" screen at one point and did a System Restore from about a week ago, but that didn't fix anything.
It shows up on my network, but I can't remote desktop into it (probably not enabled).
