Weird error

[tattoo]

After i hit F12 i get a screen that pops up that looks like the video went crazy( reddish with symbols everywhere ) and then reboots

I have 2 of the same computers doing the same thing, but i can still ris the 3 other types of computers fine

i was playing with the base image to get the new Q35 intel drivers to work, but im using the original image to solve this problem

any Ideas

Thanks
