Thank you for your quick reply:
Prior to the error, there were 3 things:
1) I am 80% sure avast did an update. I am 100% sure I updated some windows files using windows update. It asked for a restart but I didn't, I went to 2) instead.
2) I did a disk defragmentation, and a chkdsk /r. Right after, or just when I finished the chkdsk, something went wrong as I had to press power button to get away from black frozen screen.
3) Booted up computer, worked fine for 12 hours. Tried to turn it off, but It without luck, had to force it off by holding in power button again.
Rebooted today, and now the problem described in the title arrised.
I tried your fix, but still have the same problem.New log file:
