I have a problem with my machine, which I hope someone out there could help me with.

Basics: I run a Athlon XP 1800+ with a 512MB DDR333 RAM. Via KT400 motherboard with intergrated sound, network, fireware and Radeon 9000 Pro Graphics card. I have Four HDDs all different makes and sizes, two are connected using RAID. OS Microsoft XP version 2002

Problem: I was using up to a month ago one HDD for C:. The problem was it was only 2Gb. Over time this got full and I was running for some time with only 10Mb of free space. So I went out a purchased a small 20GB drive. To make the transfer I decided to create a backup of C:, (using the backup tool) on to the new HDD, then make the switch. This did not go to plan. For some reason all the files were not copied. All the prgrams in C: were not copied. When I first booted the new drive, all appeared fine until it got stuck on my desktop, I realised after some time that explorer was not copied. I went through all the programs and found over 100 Mb missing. I then decided to take the old c: out and put it into another machine. I did this as I thought maybe if the machine is using the C: drive it can not copy all the files. So in my other machine I did the back up. This time more files were copied but still not all. By this time I was fed up and So I stuck my XP Pro disk in and run an upgrade. All went fine and I thought all was back to normal. The problem is I can no longer access the registery, not with regedit or regedt32. What happens when I type either command is the program runs for a second and then closes. The same happens with the task manager.

Any Ideas??
