My computer has been turning off at random times and so I checked some of the topics on the forum and used speed fan to find out. It says my CPU is running at 86 degrees celcuis and my aux is running at 126 degrees celcius.
What should i do to fix this problem?

It would be helpful to know what kind of computer you have. One of the most common reasons for overheating is a buildup of dust inside the case. Open your case and see if there is a build up of dust on the CPU heat sink and fan assembly, if the is use canned air to blow it off. If you place a pencil through the blades of the fan you will better results blow off the blades. While you are looking at the heat sink make sure that it is securely attached. If the case has dust inside you may wish to look at the openings where air is drawn inside, you may have to remove the plastic front panel.

Another possibility is that the thermal compound may need to be replace between the heat spreader of the CPU and the heat sink.

Family and loved ones will always be a priority in my daily life.  You never know when one will leave you.

Additional comment: 85 to 90 degrees Celsius is pretty much the upper limit for most processors where I've looked up the max heat.

Too high for continuous use.

I've had processors run 55-60 Celsius (within range) and become alarmed over the lack of proper ventilation.

This link is old, but it will give you an idea of what has historically been: CPU maximum temperatures - http://www.pantherproducts.co.uk/Articles/...peratures.shtml
