The graphics engine in the G41 chipset is not supported on Windows 8/8.1 nor on Windows 10. This doesn't mean that these versions of Windows cannot be used; it simply means that no native driver for the graphics engine is being provided or supported by Intel. Microsoft provides a compatibility driver that provides basic support, but as you have seen, it has its limitations. Further, if this driver has problems supporting your particular motherboard's implementation, Microsoft offers no relief. Their stance is, if it works, great; if it doesn't, well, don't call us.
Intel supports a graphics drivers for the G41 chipset on Windows 7. You can download it here: "https://downloadcenter.intel.com/download/18842/Intel-Graphics-Media-Accelerator-Driver-for-Windows-...". This folder identifies the version as being for one of Intel's Desktop Board products, but it should work on your board as well.
Hope this helps,
