Hi All,

I would like to ask questions regarding my cMP 5,1 booting problems with Msi radeon HD 7750 installed (The original one dead, so I bought a cheap one).

I installed a new copy of Sierra and during that process, I can see every configuration on the screen.

The problem is when I tried to boot from normal mode, it chimes, hd spinned, no lights error indicator on board. After waiting for a while, a screen shown with weird scattered red or sometimes red strips. so that I can't read or see anything else. I tried all outputs to monitor, same results.

Then, I boot into safe mode, there it is!. It works. Everying shown normally on a screen even I was in safe mode now.

So, I guess, my new GPU is fine but I don't understand why it can't boot into normal node.

Thanks for any suggestions.
