Graphics glitch after CMOS reset

So I turned my hack on today. It booted straight to BIOS, I exited and restarted, booted into El Cap, but my mouse didn't work and my dual displays were mirrored instead of extended. Did a hard reset and from that point on I got nothing on the displays.

My Hack:
GA-Z77X-UP4- TH
i7-3770k
HD4000
OSX 10.11.6

After some messing around with memory, reseating, etc. I pulled out the cmos battery for a minute, put it back in and it worked!

I loaded optimized settings, and changed a few other settings back to what I remembered them to be. I had trouble setting the boot order but once I did, it booted into El Cap, but still with mirrored displays, I changed the pref to extended and that worked.

But now my problem is: glitches in graphics on both monitors (HDMI & DVI)(writing this post it glitches when the cursor blinks, or when I mouse over something or click something or the page is loading. (seems to be in Chrome, but not finder, sys prefs, etc.)
Also my display preference to extend desktop won't hold after a reboot
And boot time is way longer

I've attached an image of the glitch while moving the mouse.

PS. Sorry if this is in the wrong section. I seem to get it wrong every time I post here.

UPDATE: The glitches only seem to be occurring in Chrome, not Safari.
