Are you using the onboard display or an extension slot and card? Gigabite has the ability to turn off and on both the AGP or PCIeX16 slot and the onboard video in the bios. (Noting: some 945 variations have onboard video and some don't, some later versions of the 945 have PCIe X16 slots, some older versions have AGP X8 slots) Check to make sure your bios doesn't have these turned off for what ever you're using.

Thermal shutdown of the processor can be cleared up by the correct application of thermal paste or a liquid cooler block and an efficient heatsink and fan. It would seem that if you are running a system that is baking the processor at 79 degrees, there are serious processor demands being made. If you are overclocking or gaming with settings set to high, then you are going to have to go above and beyond the stock cooling rules or you are going to end up nuking your system. The thermal paste for a processor in a desktop computer needs to be about the size of an eraser head and then it needs to be spread very then across the processor, staying away from the very edge. The Heatsink has to be able to handle the demands of the system and the more fans the better. That motherboard should have several power points for fans, there should be fans pulling air into the case as well as fans pushing air out the opposite side of the case. Good luck
