I've never had this problem before. Every time I click on the MC exe file it slows my PC dramatically. I look at my performance from task manager and my CPU nor my RAM goes up to bad heights. It takes forever for the launcher to open (about 10 minutes.) I always end up having to restart my PC. It also does this when I try to open Technic. My MC client is un modded so there's no problem there and my PC is medium - high end. It's done this ever since I changed my operating system from Windows 8.1 to Windows 7. I can play other games, like GTA IV, Skyrim, Dayz, etc, with absolutely no performance problem. They open up and run perfectly. But when I open Minecraft (also does it with LoL) it decides to slow down, freeze, or even sometimes crash my PC. Last crash when i tried to run MC was caused by Malwarebytes. I've never had any previous problem with Mbam and MC. I've ran multiple virus scans on and off safe mode and it caught nothing. Any help could be really appreciated.
