I decided it was time to start over with my pc but hit a wall. I wanted to format everything, re-install windows. So I booted from the windows disk and only got so far before the BSOD came up. Now when I boot up it gives me the option of starting in windows or windows setup. Choosing setup just takes me through and I get a BSOD every time. How can I do this? Any help would be much appreciated. Many thanks
