I fixed it!!

I did a safe boot(Hold shift after the chime then release after apple logo appear) and rebooting again and everything is working now!

My setup:

iMac Late 2013, 2.9GHz i5

PCIe: Akitio Thunder2 Pcie Box (Powered using barrel plug method)

GPU: Galax Geforce GTX 970 Sniper Edition

PSU: Corsair VS450W

Monitor: Acer Ultrawide XR342K 34"

 

I follow the installation guide from this videohttps://www.youtube.com/watch?v=--pL5iRhpmU

 

I installed CUDA 8 Drivers for Mac and follow the video but then I have this problem with icon appearing as glitches and also the browser seems to glitch out.  How do I fix this?
