I work for an integrator and we have recently tried to standardize on the mentioned motherboard, but we've run into a problem. While idling in Windows we experience a condition whereby the display suddenly changes to a distorted mess of all colors (blue, green, red, yellow, etc) and the desktop is not view-able. This problem occurs a random amount of time after the system is powered one, between 5 minutes to more than 24 hours.
When the problem does not occur I can push the power button and the system does a soft shut down, as normal. However, when this display problem occurs and I push the power button nothing happens, which leads me to deduce that the problem is more than just display. I may add that we have also seen this same exact problem with the H67N-USB3-B3.
When I contacted Gigabyte support about it (many months ago) they suggested a few things, including booting into Safe Mode and seeing if the problem still occurs, and it did, which points to this problem not being VGA driver-related. I forget where we left off in the end, but the issue was not resolved and we had to transition to a different motherboard.
Below are my specs. The common denominator between the two boards is the processor, but we tried the same processor on an Asus board and have not seen this issue.
i7 2600k 3.4GHz
8GB 1333MHz RAM (2x 4GB, several different manufacturers)
Seagate ST2000NM9911, Crucial M4-CT064M4SSD2 for OS, both exhibit problem
7-64 Pro, latest win updates
All latest motherboard drivers from Gigabyte website
All default BIOS settings, except we use RAID mode on SATA controller
NO OVERCLOCKING EVER
Additional info:
Using Speedfan, CPU temps never above 40 degrees F, meaning issue is not thermal. Other components are cool as well.
Problem happens while doing anything whatsoever, copying data to/from drives, idling in Windows.
As I mentioned above, problem is present on H67N-USB3-B3 motherboard using i7 2600K processor as well.
If anyone has experienced this and was able to resolve it, let me know. Thanks in advance for your thoughts.
