Blue Screen after reboot

Hello, was hoping someone could shine some light in helping me troubleshoot my problem. For awhile some programs would crash randomly, and sometimes some programs wouldn't even run. So I decided to do a full reinstall, and this is where the problem starts happening. First let me list the basics.

Current Setup:
Win 8.1 (I have to use the phone# to call and activate because Key is active in another PC)
SSD Samsung EVO 850 (120gb)
HDD 1tb WD10EZEX
Asus H97i-Plus
Intel i5-4690
Corsair h100i
Gskil F3-12800CL10D (x2 8gb for 16gb)

Problem:
I'm able to do a fresh install of win8.1 onto both HD (of course not done at same time). I'm able to install the proper Chipset/LAN driver and it runs just fine, windows activates etc. However, the problem occurs when I install any other update afterwards, whether it's done via Windows Update or I manually update say RealTek audio drivers. After I install the update/drivers it just boots into a blue screen. I am however able to 'restore' from the fresh install saved point. Anyone know if this is a hardware or software issue? I was leaning towards possibly a mobo...
