JayMan, Intel® try to make as many third party components compatible as possible, but do to the sheer quantity of these third party components we cannot always guarantee compatibility. Unfortunately in this instance this would appear to be the case.
There are some BIOS versions that fixed issues related to keyboards and mouse compatibility. What we can try to do is roll back the BIOS to version 1074 using the BIOS recovery method. Then update the BIOS to the next version available which is 1084.
This link will show you how to roll back the BIOS http://www.intel.com/support/motherboards/desktop/sb/CS-023360.htm
