W10 still working fine on my PC once I'm in, but when re-starting after a shut down I get the green BIOS screen, one flash of the lights on the external backup HD, the little blue window appears on the top of the screen and the roundy-round thing starts rotating. After about 3 secs the roundy-round goes out, the small window remains and nothing else ever happens. When I press the reboot button I get the BIOS screen, the HD flashes away like billy-oh, the window and the roundy-round appears, then it all goes dark (but the mouse arrow works) then eventually the password screen appears and all is well. I can now tell from the lights on the HD if it is going to start properly or not! And no. my caps lock does not flash at all. Weird.
