He had an NV card. He installed an AMD card. He then switched back to another NV card. Sounds like driver installation fubar to me.Why express, specifically, that a problem occurs on Nvidia hardware as well? Adds nothing to the discussion as he didn't run into any issues with his new card, but did on his previous.
I am not going to tell anybody how to spend their money, but it would be wrong to suggest to anybody else with this problem that they need to spend another few hunded USD just to fix a bad installation. During my time in the military I noticed that about 95% of all problems were caused by the user, not the hardware or software. Just sayin'.
