How to Fix Your Dead PC

You might be able to resurrect your dead computer.

When your PC refuses to boot or starts behaving erratically, you might be tempted to trash that old computer and buy a new one. Before you take that drastic action, it is a good idea to try to resurrect that old computer. If you are successful, you can get several more years of service out of your old computer. At the very least, you will be able to get the computer to boot up so that you can back up all of your personal data and transfer it to a new PC.

Things You'll Need

• Computer
• Small screwdriver set
• Compressed air

Instructions

1. Shut the computer down and remove the power cord. Remove the retaining screws from the back of the computer.

2. Locate the case removal lever and use it to remove the computer's cover. For desktop computers, this lever should be on the top of the computer. For tower case designs, the case removal lever will be located on the side of the machine.

3. Look inside the computer case and take note of any accumulated dust and debris. Dust and dirt from the room will often get sucked into the case through the fan, and this accumulation of dust and debris can cause the PC to overheat.

4. Spray compressed air into the computer case to remove any accumulated dust and debris. Concentrate on the area around the computer's fan and power supply. Continue to spray the compressed air into the computer until all accumulated dirt has been removed.

5. Check the tightness of all connections inside the computer. Sometimes the connections to the hard drive, DVD drive and other devices will become loose and that can cause those devices to malfunction. Remove and reseat all the connections going to the hard drives, DVD drives and other onboard devices.
