I've been searching around everywhere for someone who may have or had this issue online but I haven't found anything. Anyways, I bought the Y410P with the nVidia GT 750M back in late July and I downgraded to Windows 7 because I disliked 8. Since then, most 3D games I play such as L4D2, CS:GO, and League of Legends will stutter at random times or even freeze up for 3-8 seconds. I've noticed at times that the nVidia driver crashes on me when playing other games or doing other tasks that do not require intensive graphics processing. I do not think I've experienced any of these problems when I was on the stock Windows 8 OS that came with the laptop. Can anyone help me out? Currently running the latest WHQL drivers (331.82).
