Thank you so much sir! This resolved my problem. I have the same mobo and processor. I bought it February of this year and its been working great until after 3 months of usage. It was so lag on games ive been playing (Tree of Savior, LOL and BnS) My FPS is dropping almost 5FPS and i thought its my Zotac GTX 970. I have tried everything, the newest and oldest Nvidia graphics driver on their website and also Windows 8, 8.1 and 10 and still the same. I was ready to RMA the GPU until i read this and Boom, my PC is back to normal and been working perfectly again. I cant thank you enuf! Kudos!
