Installed new video card and now screen is all pixelated

[br117828]

Hey I just installed a Radeon RX 460 and when I put the install disk for the driver my screen goes black for a moment and when it comes back its a pixely and the textures are all wonky. Games run really smoothly now though. Im running windows 10 OS i tried finding a bios update for my G33M mobo and i had no luck. Could it be i dont have a good enough power supply? Any help would be great. Also i know i put the video card in correctly because on the video card there is a blue light which according to the manual its been put in correctly. Any help would be much appreciated!

Hello... After a driver install you will need to set your Video card for best performance with your monitor... typically you should set it for ?x? (native monitor resolution) true color (32 bit), 60 hertz.

right click your desktop-Screen resolution-resolution... for "native" monitor setting.
right click your desktop-Screen resolution-advanced settings-adaptor-list all modes... for video card output setting.
