Timeline Won't Play Back!!!

I cannot play back video on the timeline or preview since the recent Windows update. I've dried fixing this by updating my driver on NVIDIA. Basically, I hit play on the timeline and it takes about 15 minutes to play. Clicking to different frames on the timeline takes about 5 minutes to work. My main computer is below, but I've so far opened the project on two different computers with the same results.
