Frequent BSOD

Unfortunately the dump was not triggered by verifier so no driver was identified as a likely cause. Try running it a few more times to see if we get a verifier triggered dump. PITA I know but necessary.

Verifier wasn't on when the dump occurred.

Stack trace shows Intel Graphics driver igdkmd64 was running when the BSOD occurred. Try the version 26.20.100.6859 ,A06 marked Urgent on the Dell web site. Download and install that and see if that makes any difference. Dell Latitude 3490
