if it a laptop then it looks like a fan may have failed or the thermal paste dried out. if it a desk top try opening the case and see if there a fan not moving or a heat sink that loose. if it a chipset that running hot...to find it you a hair dryer on cold...slowly move it about inside the pc case. when you find the chipset that running hot the temp is going to drop. keep the fan blowing on the chipset for a min or to to make sure that the right one. you can then by a glue on heat sink or some times you can mount a small 40mm fan to the onboard video chipset. if not see if you can use the side or top case to blow air into the pc to cool it.
I just started having these problems myself. Same motherboard by the looks of it as well. Couldnt get the computer to start... recovery disk said badsectors on HDD so i replaced that... installed new windows and it wouldnt boot. I then removed my relatively new HIS 7850 GPU and then ws able to load windows(Graphics card was having trouble starting the fan anyway). Noticed that the onboard GPU was really ho after taking out by 7850.
Now I dont know what to do... Does this mean the MOBO is failing. What are the options?
I this is a rather old post but if you solved this could you tell me what you did to fix it?
