KF crashing at launch

I recently formatted and it had been working fine, I'm using the latest geforce drivers 337.88 and KF is crashing as soon as I get to settings and try to check fullscreen.



I'm getting this error:

OS: Windows NT 6.2 (Build: 9200)

CPU: GenuineIntel PentiumPro-class processor @ 3708 MHz with 4095MB RAM

General protection fault!
