Hi. As my father lives 165 miles away, it took a little while to find the opportunity to visit and try and sort him out. So, I swapped out the PSU with a brand new unit. First couple of boots were absolutely fine, then the issue came back. Really frustrating. Ah well, have a spare PSU for when the new one dies.
As I was remotely troubleshooting this issue, I was of the understanding that the windows start splash screen occurs, do to black, and no more of the boot lad sequence happens. However, and this was news to me, I had left the speakers switched on and noticed that when the screen booted to black, all other services were loading (by sound alone). The infamous skype sign in jingle appeared as did the default windows start sound.
So, as a revision to my description of the problem, windows does boot fully, however, on occasion, all that is presented is a black screen. No cursor, nothing. Also, the monitor has not gone into standby mode. Cables and connections were checked. Latest Nvidia drivers loaded. It is a bit like saying, 'the lights aren't on, but someone is home'.
Anyhow, I appreciate all the community feedback to date. If the change in symptoms prompts any more ideas/advice, I am all ears.
thanks.

Interesting. However, the black screen WITHOUT cursor appears to be a different issue from the one WITH cursor.
I'm surprised you think it's PSU related. I am guessing that yours is more GPU (graphics driver) related. How did you come to your conclusion? And did you check the event log for clues in the startup process?
