Currently running a Nvidia 560GTX, Windows 7, 8gb ram, 3.40 ghz quad core processor. Ran ALL stress tests for CPU, GPU, Harddrives, and memory. Everything is working fine. Recently, re-installed windows 7. Deactivated on board video card, because well it's stupid to have it on, right? Anyways... I am having FPS lag in EVERY single video game I play (Skyrim, League of Legends, Warframe for example) I need anyone someone on here to give me some advice! I don't want to have to go and build a whole new computer because of a stupid problem with my current rig. I just do not understand how reinstalling windows 7 can make EVERYTHING broken with my gaming. I really don't understand. Anyone, please help! >.>
