Having a strange light issue, may be my computer, but not sure!

Hey so, I’m a new user to Unity and I decided it would be a good idea to watch some tutorials to learn the absolute basics. The moment I entered and added an object, something was off. However being the new user I was, I didn’t think much about it. After adding a sphere, I noticed that something was DEFINITELY wrong, so I messed around a bit, but nothing really helped. Here is an image of my problem:

As you can see, they look a bit wonky. I can take off or add a texture, but it doesn’t do anything. All I did was add an object, and put on a material. For the floor I put a blue, and the sphere, I put on a white metallic. The metallic definitely made it more severe, that was the point where I noticed something was wrong. However after taking it off again, I could still see a big problem. Also, the ground is a bit wacky in colors as well. If anyone has a solution to this problem, thanks in advance. Like the title it may be my computer… so I’m open for suggestions.

I think is your graphic card too old, I having the same issue with my really old laptop that using NVIDIA GT310M with latest graphic driver, but it working fine on my home PC that using GTX960 and Surface Pro 4 with Intel Graphic 530
