The system was working without problems save for one game which would make the system crash and once it also prompted the blue screen. Save for the blue screen the game in question(BF Hardline) has been reported for causing crashes even from other users.

...i say was working because after i installed the latest bios today the system became extremely unstable, now with blue screens popping sometimes as soon as windows loads, sometimes it takes a while longer. As i said, prior to updating bios any issue whatsoever was confined to the game i mentioned.

It also freezes when i enter bios, not right away but fast enough to discourage me from rolling back the bios to its prior version as i fear it may freeze halfway and possibly cause even greater issues.

The Asus Crash free bios 3 feature doesn't react to either the old or the current version of bios from the USB flash drive and the CD.

The new bios was downloaded from the Asus official website, latest version for my board, installed through the EZ flash tool in the bios itself from an USB flash drive. No problem during installation, but it got stuck on the 1st screen(with the Asus logo) after it rebooted after insallation and i had to reboot manually.

Safe mode is stable, as far as browsing through Windows and uninstalling programs is concerned. But as i said during normal start up Windows happens to crash as soon as it loads so it is relevant.

Asus Z170 Pro gaming, 6700k, R9 390x, Kingston HyperX 16gb ddr4, EVGA G2 850W. No component is OCed at the moment.
 
Solution
1) run Memtest86 free version for a full pass www.memtest86.com

2) I suspect your BIOS update changed system memory and/or CPU settings from a previously stable configuration.
a) set Factory defaults, then retest Memtest86 (if it failed before)
b) set "XMP" now if Memtest86 still failing. Otherwise, test system for a while then set later.

Other:
It may be something else, but start there.
