Should I defragment my hard drive to make my PC run faster?

Defragmenting your hard drive can help make your PC run faster, but it isn’t a panacea. Depending on the size and usage of the hard drive, regular defragmentation may not make much of a difference. It’s usually a good idea to defragment your hard drive at least once every few months, but if your PC is running especially slow, it may be related to a different issue.
