nope always on high performance

I have been having some serious frame rate issues. Generally, I get 67 frames all the time and get slight drops in 32 player pubs. Then, I press the power button on my laptop, it wakes up and BOOM, 67 frames to 15. This led me to believe there must be some viruses but after multiple scans in safe mode, nothing turned up. I uninstalled my tf folder and steelseries engine and then my frames went back up but doing all that uninstalling and re installing is extremely time consuming. Is there a solution to my problem? Is anyone else having these problems?

My computer is a i5, 8gb of ram and pretty new(got it in June). Please don't tell me to use dx80 because I like looking at shiny stuff in TF2. Also, I use Comanglia's fps config(easily the best fps config).
