Answer:
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.
