What is causing my computer to slow down?

There are many possible causes for a slow computer. It could be due to a lack of available RAM, too much junk on your hard drive, or even malicious software. In most cases, the solution is to run a scan with an anti-virus program and perform general maintenance, such as disk cleanup, disk defragmenting, and a few other basic steps. If the issue persists, it may be necessary to upgrade hardware, such as the RAM or hard drive.
