Code:
BugCheck 1000000A, {2b, 2, 1, 82c406d1}
Probably caused by : memory_corruption ( nt!MiIdentifyPfn+1e4 ) Code:
Usual causes: Kernel mode driver, System Service, BIOS, Windows, Virus scanner, Backup tool, compatibility
memory_corruption doesn't necessary mean that a RAM module is faulty, it can also point to a object which corrupted the RAM at the time of the crash, for instance a corrupted driver or program. Paging files and the CPU caches can also be causes.
Follow these steps -
Test for any corrupted
drivers, by running Driver Verifier for
least 24 hours, stop the test if a BSOD occurs before this time frame. Driver Verifier will place stress on the drivers within your system, which will cause corrupted drivers to crash and hopefully be pinpointed.
