How are you measuring 78 degrees celcius? That processor really should not be run over 75. Do you have a heatsink? Is it installed properly? Have you done anything inside the PC recently?
Iam using speccy. shows all my temperatures for my hardware. and a couple months ago i overclocked to 3.8ghz the stock is 3.5
Ok the first thing you need to do is disable that overclock. That board should not ever be used to overclock an FX processor, the power phase can't handle it. Its possible you even did some damage along the way. And yes that motherboard is not good for any higher powered 6 or 8 core FX processor, and definitely not for overclocking one.
Second download AMD Overdrive

Check your temps in there. The temp in there is based off the thermal limit (the max temp of your processor), so the higher number the better. Let us know what that number is. AFTER you get rid of that overclock!
