On an older computer which have slower CPUs and less RAM, these effects can slow down your computer. So help improve performance, you might want to try turning some or all the effects off. I am not going to promise a big improvement in your system's overall performance, but it could help.
To disable these visual effects, do the following:
- In the Start menu, right-click 'My Computer' and select Properties.
- In the Properties dialog box, click the Advanced tab.
- Under the Performance section, press the Settings button.
