Resolution problem and not able to start up games.

[ImJ0shh]

Hey there! I just installed myself a new CPU.. Which is the "AMD Athlon X4 860K".
Now, here comes the problem. When starting up my PC.. I am greeted by 1280x1024, when I usually get 1080p. Apart from that, starting up a game like CS:GO gets me another problem; Your graphics hardware does not support all features (CSM) needed to run this game.
Screenshot of error: http://prntscr.com/e5shdd .
While most of the videos I saw running the Athlon run perfectly fine.. I have searched for any drivers but couldn't find any. If you guys can help me with this, or provide me with a link to the drivers, that would be greatly appreciated!

Specs:
GPU: GTX 770
MOBO: Msi a78m-e35.


Was able to run this game before upgrade.

EDIT: Was able to run Rocket League, I have 4 fps in starting screen, maybe a driver problem?

No reason the 860k should be the cause as resolution is a graphics chip issue (not that I'm aware of anyway). The error suggests a driver issue to me; it seems to suggest your PC is running the most basic display driver possible. I would try reinstalling graphics card drivers first to see if it resolves the problem. Perhaps even a clean install of drivers. http://www.tomshardware.co.uk/faq/id-2767677/clean-graphics-driver-install-windows.html

Then there are oddities like running DX again from the game's folder...
