Last night when I logged in to my PC (Acer Aspire, Vista, 2 years old), Firefox wanted to do a security update, so I said yes and carried on reading my mail.
Firefox restarted in the background, then when I ctrl-tabbed to it, I got blue screen of death and core dump.
On restart, it offered me the safemode/normal reboot choice, and I went with normal, just to see. It got as far as the 'choose user' screen, then just hung when I clicked on my user icon.
So I did a hard reboot (finger on the button) and tried normal again - which got me as far as the 'starting' screen, where the round 'pulse' mouse pointer stopped responding, and stopped turning. Re-kill
I tried normal again, got as far as the 'choose user' screen again. This time I tried clicking on the 'ergonomy' button (for a change) - it got as far as drawing the border of the form, then froze again. Re-kill.
This time I tried 'safemode with network support'. It started loading dlls, then got stuck at crcdisk.dll. (This is where I probably screwed up...) I left it for half an hour, and it hadn't moved at all, so I killed again.
From that moment, nothing would happen - when I boot the machine, there is no boot screen, the little 'disk thinking' light doesn't even flicker, and it won't even boot from the vista recovery disk.
I'm not too screwed, as it's still under warranty, but my last backup was almost three weeks ago, so it's just those three weeks' photos I'll be losing (thankfully most of the other files I've worked on in that time are on Dropbox).
The question - what does this sound like? Disk failure? (If so, why won't it even boot from recovery disk?). I find it hard to believe that it could really be Firefox - just a coincidence? Is it my fault for killing crcdisk.dll? I'd like to have some idea of what's going on before taking it in to be 'repaired'...
