Hi, I'm not sure if this belongs in this section. But, I have a Studios XPS 7100 and its quite new (8 months old.) Here is my dilemma. Just last week I updated drivers (AMD) without uninstalling the old one. I began to experience performance issues especially in League of Legends. My fps usually ran around 58-60 consistently. However, now it fluctuates dramatically (33-65fps). I tried many solutions. I tried a system restore and even a driver roll back, and it successfully restored me to my old drivers. However, I am still experiencing the same performance issues. I did research and read that some old driver remenants can stay and one should use Driver Sweeper. But, I also read that uninstalling old ATI drivers with Driver Sweeper will cause a SP1 failure. I also uninstalled the old driver and reinstalled it ( it automatically reinstalled it when I reboot) So thats out of the equation. Right now, I'm all out of options except reinstalling Windows 7. I doubt its a hardware problem because I just cleaned the inside a while ago and never had any issues with hardware.  Anyone have any suggestions?

Many thanks, Kev
