No video after pram reset.

[Arv3n]

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?

Do you have TRIM enabled for any 3rd party SSD?

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

Do Yosemite already has native driver for 570?

No, you need the Nvidia web driver.

if you have another mac, and have enable screen sharing, you will be able to get onto the system and install/enable the nvidia driver. i had the same issue once actually.

This is without the web driver enabled and no TRIM.
