Well Dave I think it is improving.
I did a reinstall and the Windows Media Centre returned to normal, but of course I had to delete all the rubbish they put on and reinstall my own programs. So time consuming.
I ran C Cleaner again and guess what The Big Black Screen returned. But ... ... I had saved the files that I had deleted. I clicked on my saved file and they popped back - just like that! I clicked on the Media Centre and it was back to normal.
I HAVE UNINSTALLED C CLEANER.
The hard drive noise has been driving me mad. Anyway, I have disabled the indexing and my AVG was doing a full scan every day which took over an hour so I think I have altered that. Tonight the hd was clattering away again and I found that somehow Google desk top (or something like that had installed along with Google Tool Bar (which I like). Anyway the Google desk top was indexing. So I have uninstalled that.
I also found (could not find it again) a place where I could disable dropped shadow under the menu and other fancy animations related to Vista. As soon as I disabled these (about 5 things) my computer must have speeded by about 30%!!
This is crazy to supply a top spec computer which needs loads of attention to get it anything like my 4 year old one -particularly as I did a full reinstall on that and have added the Service Pack 2 again and all updates. It just FLIES and my husband keeps bragging about how fast it is. He even wanted a race to see which loaded the quicker. My daughterinlaw called 1,2 3 GO and we both switched on and his loaded quicker than mine. I do have Messenger though and as I said, I have disabled certain things since then.
Anyway, Dave or anyone else for that matter, if you have any tips into how to get the best out of Vista, I should be pleased to hear.
It does seem pretty quiet ATM and very fast.(I'd put a "Fingers Crossed" smilie here if I could find one.
