My computer is really noisy and hot
If your computer is overheating, the cooling system will fire. Most computers are equipped with one or more cooling fans that circulate the air in the housing to evacuate heat and protect delicate circuits.
- Close some programs, especially those that require a lot of processing power (and, therefore, generate heat), such as graphics-intensive games or videos.
- Make sure the air can circulate around the computer, especially near the fan vents in the back. Avoid locking the computer in a cabinet or pushing it too close to the wall.
The fan is noisy and the computer is slow
Calm your machine with software therapy
In normal use, the computer runs hundreds of mini-programs, or processes, in the background. Sometimes, one of these processes hangs in a perpetual loop.
- Your computer responds by slowing down, locking or triggering its cooling fans to cool the circuits.
- You can stop a looping process to resume normal service.
- Save all open files as much as possible. Press Ctrl + Shift + Esc simultaneously to display a new window: Task Manager.
- Click the Processes tab. This lets you view all the processes running on the computer’s processor and the percentage of the power of the computer they are using. An out-of-control process will monopolize nearly 100% of the processing power.
- To disable a suspicious process, simply double-click on its name in the list and click on the “stop” button.
For a Mac:
- Go to Applications -> Utilities -> Activity Monitor and select All Processes from the drop-down menu.
- Locate the suspicious process and click Exit Process at the top left of the window.
If the problem still persists due to the same process, ask an expert for help. It may be necessary to reinstall some of your software.
The fan remains noisy
Clean dust to make cooling less noisy
If the fan remains noisy and the computer stops when it has just been turned on, the cooling fans or their heat dissipation vents may be blocked by dust.
- Turn off your computer and open the case. Locate the fans and heat sink. They are easy to spot.
- Use a compressed air bomb to dislodge dust from the surface. An old toothbrush or a fine brush will allow you to remove more persistent dust.
- Heat sinks are sets of metal fins designed to keep heat away from sensitive components. Brush the dust on their surface with an old toothbrush to maintain their effectiveness.
Terms to know
Processor: the central processing unit of a computer is the key equipment that executes instructions written in a computer program. Computers can have one or more processors, sometimes on a single physical chip.
RAM: Random Access Memory is a type of computer memory used to temporarily store the programs used and the data they process. The RAM can be accessed very quickly and contains no moving parts.
If a disc is stuck in your CD or DVD drive, do not panic; There is a simple way to get it out without breaking the tray.
- First, locate the emergency release button on the front of the player. It is a small hole that is usually positioned towards the middle of the panel.
- Then, unfold a paper clip and gently slip it into the hole as far as possible.
- This will trigger the eject mechanism of the tray and you should be able to remove the disc.
If this does not work, you may need the intervention of a professional or buy a new drive.
