New Graphics Card. System very slow and every time I open a game the driver crashes

I just upgraded my computer with a new Gigabyte GTX970 G1 and 2x4Gb G. Skill 1600mhz RAM.
i5 4440 @3.1ghz. Corsair VS550 PSU which should be more than enough.

after the installation the computer is running very slow Including start up and every time I start a game the driver stops working.
I have already performed a clean installation of drivers, down clocked the card, tried every Ram stick seperatly.
Please help me I'm out of Ideas!!!
