It refused to start this morning. It would get as far as the splash page and no further. It had done this occasionally recently, but previously did start on the 2nd or 3rd try. Not this time.
But today is also the hottest day so far this year, and I do not have air conditioning in my home office.
I also don't have a temperature chamber at home. But the 'scope just fitted in my fridge. After about 20 minutes cooling down, it started OK.

I'm sure you may well have already tried this. but did you try booting it without any probes plugged in (cf my problem immediately above)?

Sorry - I should have included that I tried the other suggestions first (remove mains (and obviously reconnect!), then remove probes). Still stuck at the into display.
Error Log reports 0 system errors
Also, Powerups: 579
Operating time: 18988 hours
Just tried power cycling (I'm stopping now, so doesn't matter if it doesn't start!) - and it started!

Has this gone away now (as mine did once I'd figured out I had a probe interface issue), or is it still a problem?
Once it's actually started, does it work flawlessly? (In my case, it would crash or reboot anything from a few minutes to a few hours after switching on, as well as on boot).

Once it started it stayed working. I do not think I have ever seen it reboot after power on.

OK, so it only fails at startup, and it still fails at startup (sometimes)? Or have you just left it switched on (understandable!).
Yours has about 50x the hours of mine, but only about double the power cycles.
