I've built a few systems recently and although the hardware seems ok (passed 24hr memtest etc), I'm getting corruption on the console.
These are Intel Z77 systems with a Core i7 3770 CPU so using the graphics built into the CPU.
Any ideas what this could be?
Does it look like a hardware issue to you or could it be the driver?
The intel drivers are so common I figure its pretty unlikely but really want to get this fixed.
I'm using kernel 3.4.28
