Hey everyone.

I've put in a GTX 570 in my Mac Pro 1,1. Every time I pram reset I don't get any video no matter how long I wait. I'm running Yosemite.

Any ideas as to what causes this? Any way I can fix it?

When you reset PRAM you need a supported graphic card to boot so you can install the newest web driver from Nvidia.

This is without the web driver enabled and no TRIM.
