Theme Service Continuously Turning Off?

Yesterday, seemingly out of nowhere, my theme started messing up. I noticed the scroll bar in google chrome looked like something from windows classic, and some other windows had the same look to them. I thought maybe I'd accidentily changed the theme or something, so I right-clicked the desktop and chose "Personalize", but all themes other than Windows Classic themes were greyed out and I was unable to click them. I hadn't installed/uninstalled anything that day.I checked services.msc and sure enough the "Theme" service was turned off, but it was still set to automatic. So I turned it on, and a few minutes later it turns itself off again.I've tried a system restore to about 5 days before. I've run virus/malware scans, they found nothing. I've rolled back my video drivers, and nothing has worked. Other things to note are that it seems like only some stuff is classic. The task bar still has the aero look to it, but blacks out in some parts. The actual window appearance of windows seem to still use aero, while the inside looks classic.
