What to do?

One of the causes for devices not working could be cable related. It could be something as simple as the cable not connected. It can even be that the cable is loosely connected. The first thing to do is to check if the cable connecting the device to the computer is properly connected.

The next obvious thing is to check the power supply to the device. Check if the power cord/cable to the device is proper. Check if the power switch is on. A wireless device like a wireless mouse needs a battery connection. Check if the batteries are working.

Once you eliminate the simple causes, you can look at other reasons for devices not working. The next thing to check is the port to which the device is connected. The port could be physically damaged or have something clogging it. This can cause your device to fail. If this is the reason, you may need to call a hardware expert.

More ways to resolve the problem

If you have two ports and one fails, then you obviously cannot use this port to connect a device. Consider using a USB hub. Connect the hub to one of the ports. You will now have access to multiple ports to connect your devices. This is a good way to solve the problem of one of the ports not working.

Disconnecting the device and reconnecting may be helpful. When a device connected to your computer doesn’t work, switch it off. Remove all the cables. Reconnect the cables again and restart your computer. This can be helpful in many cases and solve your problem of devices not working.

What to do?

You can use a tool like Speed Fan to regulate the working of your fan. Too much of a sound from the fan can be due to the fan not working properly. In this case, you can replace the fan. You can even consider buying an external computer-cooling fan.

The whirring of the hard disk can be a serious problem. Your hard drive should not make any abnormal sounds. If you hear clicking sounds or any other sound from the hard drive, it is a danger sign. Your hard disk could be reaching the end of its life. Check the hard drive using a tool. If the noise continues, then consider replacing the hard drive.

Now, if you have a CD/DVD drive, it should not make any noise when not used. If you hear a spinning noise, it could be because a CD is inside the drive. It could be due to a broken part or the drive not working. Open the drive and check if you see dust or something in the drive. If you still hear the noise, there could be a malfunction and you need to replace the drive.

More ways to manage the condition

A beep sound from the computer is ominous. It is a sound from the BIOS. It could indicate a problem with the CPU, memory, or power source. Hearing beeps repeatedly is a serious problem. This could be a sign of a hardware problem that could lead to hardware failure.
