I found the problem... it was the oddest thing. This little file name misurp.exe was running on my computer. Whenever my cpu was active the file would lag up and take 50% of my cpu. I have no idea what the file is or where it came from. Taskmanager says it's a system file and I know it's not a virus or adware. Anyways, I kept it but just placed it somewhere else so my computer doesn't automically run it(even after I stopped it, my pc just ran it again when it was in its initial folder). Now my computer is running fine.
