Hard drive noise can be an indication of a failing hard
drive but not necessarily in all instances. Many drives will make humming or clicking noises during normal operation as the platter (where data is stored) spins several thousand times per minute causing the drive to vibrate. This vibration can result in a humming, rapid spinning or clicking noises which are transferred to the computer's case. Other noises such as squealing, rattling, beeping, or scraping are often caused by mechanical problems within the hard drive.
In some cases, the spinning noise can be due to loose connection screws or components too close to one another. Relocating the hard drive to an area with more space, tightening screws, installing silicone bushings under the screws and placing silicone rubber jackets over the hard drive, power supply and fans can reduce metal-to-metal contact and eliminate the vibration. In other cases, dirty components (cooling fans, power supply, CPU heat sink, etc) can causing the hard drive to work harder than normal resulting in rapidly spinning noises. For example, the fans on graphics cards spin at very high speeds and can be very loud when they become dirty. This noise can be resolved by a simple cleaning of all internal parts within the computer.When was the last time you cleaned the inside of your computer?
Dust restricts the airflow and prevents proper cooling. This in turn can cause overheating and faulty processor fans which can result in unexpected shutdowns, random restarts, booting problems, etc. If you use a notebook, they get dirty too and need to be cleaned.
How to Clean a Computer Tutorials with Screenshots
- Clean out the vents on the computer with a can of compressed air using short bursts to ensure that they are not clogged with dust.
- Unplug the computer and everything from the back of the unit (be sure to note where to plug it back in).
- Open the case and clean out any dust and debris you find inside. Be careful not to aim the compressed air directly at the circuit board or electronic components.
- Important! Be sure to discharge any static electricity BEFORE you touch any of the components by touching the bare metal inside surface of the case. Do this FREQUENTLY while you are working.
- Check all the electrical connections and make sure the fans are all operational.
- Remove the cards and RAM modules, clean the contacts and reseat them.
- Check the heat sink on the processor to ensure it is not blocked with dust or debris.
- Remove the CPU's cooling unit and clean the fins on the heat sink that sits under the CPU with a can of
- Feel the CPU heatsink when it powers down. It should be warm to very warm but not hot.
- Inspect the thermal compound between the CPU and heat sink as it can deteriorate over time so. You may need to remove it, scrape away the old thermal gel that makes contact with the processor, then apply a very thin coat of fresh thermal grease on the surface and fit the heat sink back in place again.
- Inspect the capacitors on the motherboard for leaking, bulging, foaming, or discoloration.
- The airflow inside the case is from front-to-back and from bottom-to-top. Carefully arrange the cables so that the airflow will be unobstructed when closing the case.
- Continue to monitor the temperature of your CPU, motherboard, hard disks, voltages, and fan speeds.
- FOR LAPTOPS: Obviously, you cannot open the case. However, dust will build up inside a laptop as well. Use the compressed air to blow out all of the ventilation holes.
:Note: Some video cards can generate such intense heat while playing games with high quality graphics that they require a separate cooling system. If the fan fails after wear and tear with age, the video processor will not be far behind and your system may start crashing.
