cluberti Posted March 7, 2010 Share Posted March 7, 2010 Please note that unlike most cases where people blame bugchecks on bad memory and are incorrect, these actually *are* potential memory failure bugchecks, so you may actually have bad RAM in the system. I'd be checking that, because all of the bugcheck codes you've shown (c21a/4e) happen when a memory location lookup fails, either due to a faulty pointer or a page fault during a non-paged operation. Given it failed in Windows *and* when booting from a (very) minimal Windows PE boot disc, this is at least one scenario where I would test memory. Again, it's possible the RAM is fine and your bugchecks are just coincidence, but the likelihood of that is fairly slim. Link to comment Share on other sites More sharing options...
