How to Speed Up your PC?
1. Regularly Update Your Hardware Drivers
A hardware driver is a small bit of code packaged in a file, which tells a computer system how to utilize a piece of hardware. Every component in a computer system requires a hardware driver to function, whether it's the printer, digital versatile disc (DVD) player, hard disk, or graphics card. Updating a hardware driver can also add new functionality to the component. Mouse drivers, for example, commonly include added features and improved configuration menus with updated drivers. It is of vital importance to update your hardware drivers, like graphic cards and embedded graphic card. My Vista Home version could not support the Aero theme and after I updated the drivers for the embedded graphic card, everything is just going on well. Therefore, I strongly suggest that all the average PC users to regularly update their hardware drivers to make sure that any bugs or extra functions have been updated from the original manufacturers.
2. Disable Unneeded Windows Functions
Open the Control Panel, choose Add/Remove Applet, click the left-side list to enable or disable the Windows functions, and then clean up the unneeded functions which are associated with the specific information when you move the mouse hover it. I leave only XPS Viewer, Portable Storage Management and Compressing functions.
