If the problem goes away, it was the part. Component age also plays a role in its failure. Most computer parts, if properly cleaned and maintained, can last 5 or more years. However, just as humans, components simply fail after they are used for several years. Overheating is another cause of hardware failure.
Most computer parts generate heat.
Always clean your computer and remove dust and dirt. Dust and dirt can cause increased temperatures and short circuiting inside a computer. Power surges , especially repeated surges, may also cause hardware failure. Connecting your computer to a surge protector, or uninterruptible power supply can help protect your computer. Troubleshooting a Software Problem Always start with the program you most recently installed on the computer.
