That's annoying

I went to switch on my desktop computer this morning and it didn't go to the Windows log in screen. Powering off and on was no help. Finally I disconnected all USB devices and the ethernet cable and was able to get to a diagnostic screen. It seemed to think that I had not enough space on the Windows drive, although when I finally got to the command prompt, that seemed to think I had plenty of space.

A disc repair doesn't seem to have worked. I'm now trying a restore from Thursday.

I reckon on replacing my desktop ever five years and I got this one just before Loncon in 2014, so I was planning on replacing it soon. But I'm going away this week, and I don't think I'll have time to replace it before I go on holiday.
