My initial problem, which began yesterday, is that Windows is hanging on the shutdown screen. 10 hours now and counting - I switched off when I went to bed, it's still switching off.
I notice that there are a few threads and I will have a look through the threads on here, see what people suggest.
This thread here: Windows 7 64 bit Hangs on Shutdown & More
looks like the one to follow. If those steps work - great
Problem is, if they don't then as gregrockers says "There are even more steps once we are convinced you have completed all of the others. Start at the top of the thread." - is there a link to these subsequent steps? Does anyone have them in a readily accessible format so I can just follow them without having to bother people for support? You're all lovely people and I hate to waste your time and good will with stuff I could just follow and get fixed.
In the meantime I'll start at the top of that thread and work down.
