15" MBP Retina, restarts at random. Sometimes when I or it restarts all my TrackPad setting are delete/reset, almost like I have bad NVRAM. Also my screen wont turn ON if I reset NVRAM by holding Comand Optoin R P.. After a nvram reset, laptop turns on with the screen OFF, I have to put the computer to sleep and then wake up the computer for the screen to come ON.

I think its this causing it: com.bresink.driver.BRESINKx86Monitoring

Problem is that extension is NOT in folder: /System/Library/Extensions

Where else could this extension be?

I need to delete it and see if that,s the problem.

What I've done:
- deleted all unecessary apps that could cause crashes.
- after nvram reset tried starting up in disk select mode by holding option but still screen OFF
- tried booting up in safe mode by holding shift but still sreene is OFF
- tried booting up in restore more and the screen is still OFF

Only way to get the screen ON is to put computer to sleep and wake it up.

Also if the laptop is at SLEEP for a long time say over night, in the morning when I wake it up it has Kernel PANIC and has this crash report:

I found the extention in the /System/Library/Startupitems folder!! Now I have to see if I'll get a Kernal Panic crash again. I'm hoping that was the problem

For anyone in the future laptop need these drivers deleted for startup folder com.bresink.driver.BRESINKx86Monitoring

and simple SMC restart (google mac SMC reset).

2 days worth of work to figure something so simple out, can't believe on one here suggested this to me.
