Illustrator display issues on Windows 10

Hi guys! New here. Apologies in advance if this a double posting.

I'm using AI trial atm on my personal lappie and thinking to purchase if it works well. (Specs: Asus N55S, i7, 8MB RAM, GeForce GT555M, Win10 - I know, it's old but reliable)

Problem is, every time I launch AI, it doesn't display properly (pic) until I fiddle around by selecting Outline View or GPU Preview. Initially when I tried to 'Create New' all I got was a blank display box. I solved that by turning on Legacy File New setting as per another thread here, but this problem still persists, and it can be any file that I open - new OR old - but I still have to mess around with Outline/GPU before I can get it to show anything, or even the art board.

Is this a bug? Anyone know how I can solve this issue?

TIA!
