I asked about my slow to boot (and sometimes slow to shut down) pc a while back now and have htop installed. I should have asked this then but which bit of the info it gives me do I need to give you lot in order to diagnose the problem?
OK, You need to start HTOP whilst it's being slow. You can either start a command prompt from the menu system, but I think the best way would be to CTRL-ALT-F2 to bring up a full screen text console. You'll need to log in using your usual user name and password.

Sorry it's been an absolute age since I said anything about this. I can’t log in while it's booting to check but I can raise htop directly afterwards.
(At the moment CPU 2% - 4% and Memory c 648.0 of 991.6 MiB I'll check again though. I have checked the Startup Applications and there's barely anything listed.)

Well, if it's being slow and you run htop, if the processor (CPU) usage is high, then the top one or two tasks will show you what's causing the slowness. However, if it's being slow, and the top tasks are only using a few percent of the processor, then it's not processor hogging that's the problem. if this is the case, run top (not htop) and see if the number before "wa" is high. If that's the case, the system is "waiting" for hardware - usually a disk. Again, if this is the case, try sudo iotop
Do you mean 'id'? If so, a huge figure. 99.2. If you mean 'wa' then we can rest easy. 0.0 - 1.0
df -h gives us:
