I have noticed over the last few days when I was online, windows update was downloading in the background. Yesterday, it asked me to install it which I did. About three hours later the progress bar was about half way accross the screen when I got the dreaded blue screen. I restarted and hardly anything worked. I uninstalled SP2 and things are back to normal.
I could not find the SP2 that was downloaded, I looked for it before I deleted it, it was only in the add/remove bit.
All working ok now but looks like problems when I get the cd through (ordered it a while ago.) when I will have another crack at it.
