I recently switched video cards from a Radeon R9 380 to an Nvidia GTX 970... I liked using the MSI gaming app. I'm new to all this and liked that I could get a little extra juice by just clicking a button without messing with a bunch of stuff I am clueless about. I removed all the old drivers and software that came with it and put all the new stuff on it. Well for some reason, now anytime I want to change what mode I'm using on the MSI Gaming App it makes me restart the PC. It never did this before with the R9 380. Anybody know what the deal is? Is this just an Nvidia thing? Thanks for your time.
