BSOD - primarily when using Lightoom (sometimes just randomly)

i'll give it a shot and report my findings...it's getting more and more frustrating
Could this be a hard drive issue where the phtoos are stored?

question: WhoCrashed identifies 2 culprits - hal.dll and ntoskrnl.exe - what are those files and how can they be fixed?

every time i run lightroom (which references that specific drive), the system causes a BSOD
i'll try to move the same image to my OS disk and try to export...and report back on my findings

Verifier crashed as soon as I loaded into OS
will run the memdump collection now and post

PS. memdump is the same from 6/15

I loaded into Win7....i plugged in the USB drive , and the screen turned fuzzy and system crashed (not BSOD)

Mcafee uninstalled, ran Lightroom for pics of a different drive - still BSOD
i am about to kick my PC

Thanks, guys.
I am a semi-professional photographer who cannot work on this craft...and the pics i cant process...are the ones from my wedding. So you can imagine how frustrated I am
