CPU Overheat..?

try checking the bios of your computer. sometimes there is actually a temperature limit that you can set on when your computer will automatically shutdown. you can even turn it off but i wouldn't recommend it. the reason why the newer type of motherboards have this safety feature is for the prevention of overheating. especially when your computer is located at a place where the air is not circulating properly. since you did open your cpu casing, why not just leave it open. this will definitely prolong your computer usage before the computer reach it's maximum working temperature limit.

Unplug the power lead. Open up the case and check to see if the heat sink is loose. If it is, remove it and re-fit using thermal grease between heat sink and CPU. If it is fixed ok, remove the fan and clean all the dust from the heat sink fins. I use a tin of compressed air to blow the crud out. This is the most likely cause. It just might be you power supply unit is getting tierd and not putting out the full watts/volts and heating things up as it draws more amps.

I have faced this problem. The reason of my problem was that i tried to connect the power cable while the pc was on. Then i got the cpu overheat message. I suggest you should check all your power cables. Then start your computer. Go to windows & shut down it. Then after a few while start your computer. I hope this will end your problem It worked for me. Best of luck

I'm kind of confused, but maybe the overclocking feature is on, without you guys noticing it. If it is, the problem is on the CPU, if not, well maybe the room is just too hot, or the fan is weak at ventilation. That's what I can share. My CPU exploded one time because I wasn't aware of the CPU overclocking thingy, and I went tweaking it, then it exploded the time I turned the switch on.

Keep Your Cabinet in air circulating area in your room. you should check your Bios utility and change the max temperature for your PC to shut down when over heating occures obviously it may damage your system so leave the default settings. otherwise you can use another fan in your Cabinet this may reduce heat. In simple words You can upgrade your System to the latest mother board and processors.
