Computer running slow (causes, troubleshooting, fixes, desktop, laptop) (Ubuntu)

Animated pointers and high-resolution images may look nice, but they can also slow down your computer. The animations and images occupy the computer's RAM every time you start your PC and as a result there is less processing power available for other more important tasks.

So, if your desktop computer or laptop is running really slow, try to avoid using animated pointers, animated backgrounds and other third-party widgets so that you have more available memory for other more important tasks.

If too many programs start when Windows or Mac OS starts (e.g. Skype, uTorrent and etc.), they can slow your computer down. If you wonder how to fix a slow laptop or desktop computer, you should start with disabling startup programs.
