Different BSODs - KMode, Driver_IRQL

Welcome to 7F.

Your nVidia drivers have been flagged.

Code:

fffff880`03cc4228  fffff880`042e7908 dxgkrnl!DXGCONTEXT::Render+0xadc
fffff880`03cc4230  fffff880`06cee2bbUnable to load image nvlddmkm.sys, Win32 error 0n2
*** WARNING: Unable to verify timestamp for nvlddmkm.sys
*** ERROR: Module load completed but symbols could not be loaded for nvlddmkm.sys
 nvlddmkm+0x86f2bb

For testing purposes, download this earlier version from here and follow NVIDIA Drivers - Avoid Problems for the cleanest possible install. Basically the latest drivers aren't agreeing with your system.

You're welcome, hopefully that resolves your issues. :)

OK, this time we have a few drivers showing themselves. They're detailed below.

1: Your nVidia driver has been flagged again.

My advice here would be to browse through the available nVidia drivers for your card via their advanced search to find a stable driver for your card. This could involve a fair bit of trial and error and patience.

Remember to follow NVIDIA Drivers - Avoid Problems each and every time you change drivers for the cleanest possible install. If your card keeps flagging up as a problem we'll look at testing it to see if the problem lies with the card itself.

2: Your VirtualBox network driver has been flagged.

As you can see from the timestamp it is old and needs updating. Check for updates here or on the ASUS support page for the P8Z77-M Pro.
