I'm having problems with a sluggish computer. What are some of the most common causes of a slow computer?

1.  Too many programs running at once can cause your computer to slow down.
2.  If you have too many programs or files open, they can take up memory and processor resources slowing down your computer.
3.  A virus or malware infection can also cause a slow computer.
4.  Hardware issues such as a failing hard drive or outdated RAM can also cause a slow computer.
