There are ways to pinpoint which driver it is, as it diffidently looks like a driver issue.

Hi all, We have a couple "identical" laptops which have suddenly started generating bluescreening. Seems to happen every few days to once per week. They both crash with the same bugcheck code and parameters and driver and addresses. It was happening before the June patch Tuesday. Based on user reports, it started happening within the past few weeks, so it might have been the May MSFT patches, I suppose. Google either finds nothing or way too many random unrelated problems. (Or Arabic. Odd.) I was wondering if anyone else has seen recent problems like this? I hate to try rolling back patches and/or updating drivers at random in the hopes that the problem will go away. Any suggestions/ideas welcomed. Both are Dell Latitude D430 laptops, running Windows XP Pro with Service Pack 2.
