Aman/Igo/Meghna:
Try to "attempt to load the last known good configuration". Also
here is a good utility to analyze the dumps. Would love to check the BSOD dumps, you guys are getting, but do not have enough time. And
Step C, from
this URL, tells and guides how to use the Debugging Tool. While implementing the corrective measure, you might do registry changes -- take backup, and install new software -- create a roll back restore point.
Also regarding OC. I have been using Win7 Ultimate, 64BIT for quite some months. No issue with stability. Yes, I have had 3-4 BSODs, but I pinned them down to some registry errors and corrupt installations.
