Hi again Davey, I've come back to report to you where I am now. I did go ahead and reinstall windows in the end. It's taken me about a week or so to get my pc performing well and installing the browsers, programs and internet, and so on. Well Davey, after all of the reinstalling I have done I only have one registry key that keeps coming back. It is the same one as before (I had 21 or so before reinstalling) I have noticed when I right click on CCleaner it takes me to regedit where there is an open folder, does an open folder mean that there is nothing in it and it is safe to delete? It's one of those ARP cache management keys, thank's in advance Davey, totallyskint
