New PC showing Blocks and complete lockup (Pic included)
I recently built a new PC for my friend. Everything pretty basic.

BIOSTAR H61MGC LGA 1155 Intel H61 Micro ATX Intel Motherboard
I built it at my house got it all setup and running fine with Win 7 and then hooked it up for them. About a week later they start to see this on their screen which is followed by a total lockup of the system that can only be fixed by powering down the system.
What Ive done so far.
Hooked it up at my house and ran memtest. I saw similar effect in memtest where it was blocks with smiley faces of some sort inside them. Computer completely locked up had to restart. Other than that memtest detected no error in the ram.
Updated BIOS to newest version. I left the PC running for 24 hours after updating BIOS without any problems. Sent it back to their house and the problem is still occuring for them.
I do not know what else to try at this point other than returning the mobo or CPU. Im not even sure what would be at fault in a Sandy Bridge CPU.
