You might not necessarily be your motherboard having freezing issues it might be your video graphics drivers you may have to go to the website where your graphics driver was processed weather be nvidea or ATI Radeon and see if they have updated drivers for your version of Windows
Of course the problem with that is if they don't have an updated version of your graphics drivers for your version of Windows and you're still having issues but it was already updated you may have to roll back your driver to a third party proprietary driver
