My PC was shutting down right after Windows XP Pro came up. Regprot asked whether to allow dumprep. I tried several things and finally put dumprep in Process Guard. My system seems to be working ok for the moment. I searched the internet and found a recent XP forum on it, but it didn't explain it. I think dumprep is a Windows file and Windows seemed to regenerate it if I deleted it. Do you think something else was running off of dumprep? Dumprep and a version of itself in the Windows prefetch folder at first.
