@JohnReaper123, please update your profile (personal details) with your Motherboard (Mobo), CPU and iGPU or Graphics Card.

Profiles need to contain at least your primary system to assist others with helping you.

Is your CPU a Core i5 3330? I have never heard of an Ivy Bridge "Core i5 330".

There has been reports that older Nvidia graphics cards like your 550Ti may not work correctly with High Sierra but still work with Sierra. I suggest you either go back to Sierra or, if insist on using High Sierra, you may have to replace your graphics card with a High Sierra compatible one.
