Try running CCleaner, Malwarebytes and through an elevated command prompt sfc /scannow.
I also believe what roban said there not the fastest opening and operating programs. For video try a proggie like vlc which is more light weight. Photo Viewer on the one hand should open ok but can take a while flipping through photo's depending on there size but that shouldn't be that much of a lag. IE is slow opening, try Firefox or Google Chrome. Also do as roban said stated and clean, scan, and test with sfc /scannow..
