Jennifer recently bought a new computer to type a new manuscript she’s been working on. She also stored a lot of movies on it to watch during her free time. Though the performance was good at the beginning, it deteriorated quickly over a small period of time. Which is the most likely cause?

Declining free space on the hard drive

Explanation:

Although heat is one of the main factors that shortens the life of computer parts such as the central processing unit, the major cause of deterioration in computer performance are usually program build-up, too many files including video, music, and picture files, and other forms of viruses and malware and incompletely installed programs. This may eat up free space on the hard drive, which leads to slowness.
