It is very likely that your computer has excessive dust keeping the fans from distributing air for cooling within the unit. It can also be an issue with the power supply fan not working. First, verify the fan is turning properly. If not, replace the power supply. The same thing can be true for the cooling fan for the processor. Check to make sure it is running. To do so will require you to look at it with the side cover off and computer running thus posing a RISK of ELECTRICAL SHOCK. UNLESS YOU ARE CLEARLY VERSED IN HOW TO DO THIS, I ADVISE TAKING IT TO A COMPUTER STORE.

If these two fans are working properly, cleaning the dust inside the computer is the next step.

Disconnect electrical cord from the computer, ground yourself by touching the case to eliminate static electricity, remove side cover from the computer.

Using "canned air" widely available at computer or office supply stores, blow out the dust from the power supply and interior of the computer.

Emachines t5212 overheat message then shuts down


Three causes of ovheating:
1) Dust. Dust inside the computer, Dust around the vents, fans, cpu and heat sink. Take a can of compressed air and clean the dust out of the computer.

2) A Fan not working. Make sure the fan inside the Power Supply where you plug the power cord in works. Also there is a fan that sits on top of the CPU and Heat Sink. Make sure it works. Normally the system will give you an error message if the fan is not working.

3) Thermal Paste - The Thermal Paste around the cpu and heat sink has dried up or is too thin to keep the unit cool. Apply a fresh coat of Thermal Paste on the CPU and Heat Sink.

Computer keeps shutting down.


Do the fan's spin when you power the PC on? All of the fans should spin up for at least a second upon initial boot. The CPU fan and video fan (if you have an external card) will spin the entire time the PC is on and vary in speed depending on temperature.

Try booting the PC with the side of the case off and note and fans that aren't spinning. The temperature to shut off the CPU is really high. If the temperature is getting hot enough to do this, you should notice a failure in a fan right away.

CPU fan stops, computer shuts down


You must have the CPU fan plugged into the CPU fan power connector or the system can not monitor the fans speed. Your PC will shut down & give you that message. (The fan must be connected to the correct power plug).
If when you did replace the CPU's fan & had to remove the heat sink, which is where the fan screws into & did not clean the old thermal grease off the CPU & heatsink & replace with new thermal grease than your CPU will still overheat. If you add thermal grease over top of old thermal grease your CPU will over heat.
This is all a balancing act. If any one is not correct your system will shut down. (This is better than killing the CPU).
To remove old thermal grease use a clean cloth damped with house hold alcohol & use the same on the bottom of the heatsink. Please allow plenty of time for the alcohol to dry.

Good Luck! Take your time.
