dxgkrnl.sys BSOD BCCode: 0x00000116 DirectX Graphics Kernel Error

So basically I got this Blue Screen of Death which caused the screen to have black bars often when scrolling and then just freak out before causing the screen to go black and then showing the BSOD error screen:

Small note on my computer, It's a Dell XPS 8100 in which I switched the dying Radeon 5770 for a Radeon 7770 and replaced the crappy OEM power supply with a CX600 watt corsair one, as well as replacing the ram with kingston hyperx 4x 2GB sticks and a new western digital hard drive.

System Info:
OS: Windows 7 Home Premium 64-bit (6.1, Build 7601)

atikmpag.sys (ProductName: AMD Driver, File Description: AMD multi-vendor Miniport Driver)

NOTE: I am fully updated on all important Windows updates besides a silverlight update and security update for Internet Explorer 11, which I don't even use.

So basically, how do I fix this and prevent it from reoccuring?

Try removing all traces of your graphics driver...Then reinstall the most current driver.
