BSOD then reboot cannot find boot drive

I am having a few problems with blue-screening. I cant replicate the actual event which causes the BSOD, but
the real problem is after the computer tries to automatically reboot. Here it falls down as it cannot find the boot drive and I get stuck in a boot loop.

If I turn the laptop off using the power button and then turn it on again it boots straight up.

I'm on a dell latitude e6420. If you need any other information please let me as I'm keen to sort this out.

EDIT: I've uploaded the zipfile now.

Unfortunately there are no dump files in your logs, follow BSOD Minidump - Configure to Create in Windows 10 - Windows 10 Forums to ensure you're set to create MiniDumps.

The first driver I can see is the FTDI USB to serial adapter driver. I'm not too sure what it's for but it's very old and either needs updating from here or removing.

Code:

Also check the Dell support page for your machine for an update to your nVidia driver.
