So this started happening a few months ago a while after I upgraded from a Radeon 7950 to a gtx 960 not sure when exactly it started.

I was first using a Logitech g300 or g350 when it would randomly completely disconnect for up to 10-15seconds, then Razer Deathadder disconnect problem stopped but mouse kept freezing, now I have bought a Steel Series Rival 100, the problem is the same on all mouses, i've tried different usb ports / reinstalling the game.

This problem has only happened in tf2, only last night have this problem happened in tf2.

I'm using chrismaxfps(frames idk) cfg / rayshud

keyboard freezing doesn't happen as often as the mouse freezing, when the keyboard freezes it'll keep holding the last key I was pressing.
