I also forgot to add that I ran the Intel processor diagnostic tool and it said the graphics were functioning properly. I then tried and external monitor while the laptop monitor was scrambled. The external monitor showed the same scrambled image.

I understand the video screen does not seem to function properly. That is unfortunate.
After connecting an external monitor and installing a different operating system and the problem still persist, this definitely seems to be a hardware problem.
Does this issue still happen when you test one memory stick at a time?
If the problem continues, please check with Lenovo for warranty options
