Hardware issues
If your computer suddenly stops working, the first thing you should check is the hardware. Hardware problems are often surprisingly easy to solve. Here are some hardware-related points to check if your computer stops working.
Check the speaker or headphone connections
The first thing to check is whether your speakers or headphones are connected properly . Especially on desktop computers, they are often connected to the audio jack on the back, so check to see if the connection is loose. Even on laptops, there may be cases where sound is not produced due to poor contact in the headphone jack . Sometimes the problem can be solved by simply disconnecting the connection and plugging it back in firmly.
Cable or jack failure
The cable or audio jack may be physically damaged . Check to see if the cable is broken or the jack is loose. It is also effective to test it with a different speaker or headphones . If sound comes out from other devices , the cable or speaker itself is likely to be the problem. In this case, consider purchasing a new cable or replacing the speaker.
Hardware issue with built-in speaker
For laptops, the built-in speaker may be broken. To check this, connect external speakers or headphones to test whether sound can be made . If sound can be made from external devices, the built-in speaker may be broken. In this case, repair may be required, so we recommend consulting a professional.
Testing external speakers and headphones
It is also important to test the audio output of your computer using a different set of speakers or headphones. If you can hear the sound on the external device, then you know that the problem is with the original speakers or headphones . Conversely, if you can’t hear the sound on other devices, then the problem is most likely caused by a setting or internal problem on your computer itself.
