You want to go to each components website and install the latest drivers, factory drivers are limited and usually very out of date. The key one is going to be going to the nvidia website and installing the most recent driver for your GTX 770. The next one on the priority list would be to go run the driver detect utility on the intel website and install those. I am guessing your games are trying to run off of the integrated graphics on your cpu and not your actual graphics card.
