Hi,
I have seen this same problem posted elsewhere and I have the same issue:
Whenever I try to update this driver:
Intel(R) Host Bridge/DRAM Registers - 9B44
Windows BSOD occurs. The crash reference is to Intel video driver igdkmd64.sys, which is interesting because I have disabled the Intel video adaptor in BIOS. Can you please advise if there has been any update on this. I have also read elsewhere that this driver does not need updating
