Normally, I run around 200 or 300 fps, with all of my settings on medium-high, But recently it slowed way down, to around 30 fps, I cleaned out my hard drive, which is an INTEL SSDSC2CW180A ATA, There is currently 91.5 GB free on the disk. After that, my FPS went super high. But now, a couple weeks later, it is now in the 40-50 fps range... I do not know why, my settings have NOT changed but it all of a sudden dropped.

That's not a hard-drive, that's an SSD. If you were defragging, STOP! IT RUINS SSDS! Please post your (full) DxDiag in Spoiler Tags (you’re shown how to make Spoiler Tags in the linked thread).
