Why are you hearing strange noises from your computer?

Today we want to talk to you about the strange noises we sometimes hear on our PCs, noises whose origin or cause we often don't know. As specialists in IT maintenance We believe it's important for you to know that some of these noises are not dangerous, while others can be clear indicators that something is wrong with your computer.

• When we turn on the computer, it's normal for it to beep, which is emitted just before the operating system starts, indicating from the motherboard that everything is working correctly. However, if the short beep turns into a series of mechanical beeps with different noises, it could indicate a hardware problem.
• The fan can deteriorate over time, so if you hear it start with a loud noise, it could be that the processor is overheating, caused by dirt on the heatsink. This leads to inefficient operation because the motherboard is working under too much load and can't properly maintain the PC's temperature. This same problem could also occur with the graphics card's cooling system.
• The hard drive may make some noise while working, but these are usually not constant or loud. If you do notice any noise, you should back up all your documents, as the drive may be failing. In this case, we recommend using our backup services. IT maintenance professional.

  • Long beep; there are faults in the RAM memory modules

  • One long beep followed by two short ones; graphics card errors
  • Three short beeps; errors in the first 64kb of RAM
