I have had unity for a couple of days now and im just learning the ropes. i must have done something wrong with the point light because when i create one, my cube/terrain/everything just goes bright white and even when i delete the light it stays white. i have tried resetting the factory settings and that didn’t work 
I assumed you’ve tried the obvious stuff like reinstalling Unity, restarting your computer.
So even when you create a new project and created a cube for example, the cube is bright white?
If so, it might indicate a problem with your graphics card. Try reinstalling/updating the driver.
When you start a brand new project and a brand new scene and make a cube, you should get a gray-shaded cube. If it’s bright white, something is wrong with your computer
