I purcchased a new Dell XPS 630 with Vista. From day one, once or twice a week it blue screens. I have had Dell support connect to the computer several times and they are claiming the ntkrnlpa.exe is corrupt as that is the file referenced in the mini-dump files when it crashes. They suggest doing a complete reinstall of Vista. If I do that, it will take me at least 2 days to reinstall all the development software I have on this computer. Is there a better way? I have Vista SP1 loaded on this computer. I have another computer with Vista SP1 on it. Can I copy its version of ntkrnlpa.exe?
