Problem installing

Hey I've tried installing Zorin multiple multiple times - at first I thought it was cause the md5 wasn't correct so i downloaded like 5 times till i finally got one that had the right md5 but the same problem kept occuring - whenever I go to any of the live boots and install directly I get to the splash screen but then it just turns into a bunch of pixelations and nothing. I've tried both burning to a dvd and usb and nothing worked. I've also tried booting it on my dads laptop on the live dvd and I run into similar problems.

EDIT: I tried running it on virtual box and it worked, is my computer not compatible probably or something or is it bad luck.
