Much like your car, your PC may sometimes alert you to the fact that something is wrong. When you take your car to the repair shop you probably tell the technician that it is making some strange noise that you have never heard before. This often helps the technician diagnose the problem.
Computers have the same advantage. Often the noises that a PC makes will tell you what the problem is. I have tried to match the noise, tough to do when writing it, with the problem. Listen to your PC and then check below to see if you hear a match. Remember, if your PC is making noise that it didn't make when it was new means it has a problem and depending on the severity could cause permanent damage.
My computer use to have a noise, but in the last few days has been pretty quite.
Stop what you are doing and check the back of your PC. There will be a grill area next to the power cord connector with a fan installed. If you can't feel any air coming out of the fan, take a closer look to see if the fan is running. If the fan is not turning (with the computer on), you may have a problem with the power supply. You must replace the fan as soon as possible. In most cases it is cheaper to replace the power supply that houses the fan rather than attempting to replace the fan alone. The fan in your computers power supply is what cools the internal components and if it's not working you will overheat the PC.
My computer makes a loud noise that is constant; it never made that sound before! Again, this is probably a fan problem; follow the steps above to make sure it's not the power supply fan. Most computers also have internal fans, they may be mounted on one of the expansion slots of your PC. You will most probably have one or two attached to the CPU (Central Processing Unit). You must open the computer case to check these. THIS IS IMPORTANT, the CPU fans must be working. With the case off, turn your computer on, NEVER TOUCH INTERNAL COMPONENTS WHILE THE PC IS ON. Check to make sure all fans are running. If there is a fan that is not turning or is turning erratically turn your PC off and check the wire power connections to the fan. Restart the PC and check to see if this fixed the problem. If a fan is still not running replace it right away. The CPU fan cools the processor and its imperative that it remains on.
Loud & Shakes
When I use my CD-ROM/CD-Writer, my PC makes loud noises and shakes the whole thing! The new high-speed CD devices make this noise because of the high speed, this is normal.
Clang Machine Noise
Sometimes my computer is makes a clanging noise when it starts and it seems to be getting worse! This noise is perfect indication that your hard drive is dying. Stop now and backup any important data that you have, because once the hard drive starts making a loud clanging sound it won't be long before your PC stops booting to it. There is no way to repair the hard drive so you will need to purchase a new one.
