Weirdest boot issue (registry issue... while PC was shut down!)

post #1 of 5
Thread Starter 
Hi y'all,

this morning my PC was fine and shut down without issues. I come back home from work and it refuses to boot.
I check whether everything's ok, and it is. All plugged correctly, SSD (boot drive) lights up fine.

I get into BIOS and it doesn't even SEE the SSD. I reset the PC a couple of times and it ends up seeing it, but when I boot from it it takes me to the Windows repair option.
First I try to start windos normally: black screen (i.e. blank), nothing happens.
I try the Windows Repair, and it tells me the issue cannot be repaired.

The logs say that the root cause is 'Registry is corrupt. Repair action: Registry roll back. Results: failed.'

How can the registry become corrupt while the PC is off? Not hibernating, not sleeping. Off.
How could I repair this?

Thanks!

NOTE:
The UEFi doesn't always recognize the SSD at all
The UEFI refuses to boot from the optical drive in which I have a windows CD...

The registry got corrupted while the computer was on, then whatever was corrupted prevented it from booting.

I'd try a Windows repair install. And then some heavy anti virus checking.

Makes sense: it's what I've been trying to do but this thing can't even boot from the CD :| I may try a Ubuntu live-CD with an anti-virus for Windows...
I had once managed to boot onto the console last night using the WIndows repair function, but the keyboard wasn't recognized (while it was under the BIOS) so I couldn't go further.

Weird thing is I don't download anything (no music, films, nothing) and the last streaming (last True Blood episode biggrin.gif) was Monday evening. Yet on Tuesday morning the PC started ok and I didn't do much at all then.

In the BIOS there's a setting for something like "legacy Keyboard" or "Legacy USB".
These are not for older equipment, but load the appropriate driver during post, instead of during boot. Hence a (USB) keyboard will work in BIOS.
