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.

due to the graphics being built in the cpu you should try what essenbe suggested and look for newer intel drivers for intel hd graphics. if no luck there then i would replace the cpu.

I had initially only used the drivers on Biostar's site. I just updated to the newest ones on Intel's site. I am running the Furmark video test but I'm only getting 1FPS. I dont see any artifacts though and it looks to be ok I think. The temp reading is just saying 0 C and not changing so I cut the test off at 10 mins. Anything else I run to try to make sure those blocks do not come back.

Google Luxmark V2.0 and download and run it.
it's a much better program.

I was finally able to repeat the effects on my screen after running a CPU Stress test with prime 95. The PC completely locked up so I tried to take a pic with my phone and when I was about to take it the blocks disappeared. However the PC was still completely locked up. I took a pic to show where I was at concerning prime 95 and temp wise. I used the blend test.

Yes everything in BIOS is default. This PC was built for someone to basically surf the net and teach their kids to use the PC. So nothing was overclocked at all. I'll try running prime95 with Core Temp and see how it works out.

Ok ran it again this time with CoreTemp. First time I left the room for a minute came back the PC was completely off. 2nd time it blue screened on me but it locked up and didnt finish dumping. 3rd time I was able to get a dump file. It points to PCIIDEX.SYS. I attached the dump.

I forgot to mention that I saw that block effect again for a split second right before it BSOD'd.
