Check to see if the fans are running if they are take a can of compressed air and blow the dust out of them blow the air backward through the fan by blowing in the exhaust vents . If you cant hear the fans then you'll need to take it apart and and change them out or figure out why there not working. If the machine has had many overheating issues before you got around to fixing it you should consider replacing the thermal paste
Hope this helps

There are many things which can cause a system to overheat. The major ones are as follow for a Windows operating system:
1) When the cooling fan has accumulated debris or the vents are blocked.
2) The heat sink is faulty thereby losing the ability to dissipate heat properly from the processor.
3) Thermal compound on the processor has completely dried up and can no longer carry out its function.
4) Running high specifications-consuming applications on a low system hardware.
5) Some malicious software using up the memory and more part of the system storage can be a culprit.
To find solution to your system you would have to tell us more about the conditions of the system.
Does the system whiz heavily at some point in time? What application do you usually run that makes the temperature to go up? What is your system configuration?
At this point in time you can try to prevent the vents from anything that can block them. Place your system on a flat table or desk when using it. Listen for changes to the noise of the cooling fan and use compress air to open block vents. Scan your system for malware and disable many applications running at the background at the 'System configuration'.
If you are good with hardware coupling and fixing you can open up the system and wipe the previous thermal paste off the surface of the processor and the heat sink and reapply new one.

A lot of dust in the fan can make it spin slowly, causing the computer to overheat over time. Open up the laptop (remove its keyboard) and take a look at the fan. If it seems to be dirty (or even if it's not, you might as well while you're there), clean the fan and make sure there isn't a buildup up dust on it, as this can cause the fan to slow down significantly. Once it's clean, double check the fan's connection to the computer itself (this is set of multicolored cables near to the fan that connect to the motherboard). Reconnect the keyboard and restart the computer. If it still overheats, then the fan is likely faulty.

Dust in the fan might be one of the main reason the computer is overheating, because it makes it spin slowly. If the fan is clean, check the connection, and if the connection is fine, the fan must be broken.
