How to make PC really run faster than before?

1.Let your PC boot up completely before opening any applications.
2.Refresh the desktop after closing any application. This will remove any unused files from the RAM.
3.Do not set very large file size images as your wallpaper. Do not keep a wallpaper at all if your PC is low on RAM (less than 64 MB).
4.Do not clutter your Desktop with a lot of shortcuts. Each shortcut on the desktop uses up to 500 bytes of RAM
5.Empty the recycle bin regularly. The files are not really deleted from your hard drive until you empty the recycle bin.

6.Delete the temporary internet files regularly.
7.Defragment your hard drive once every two months. This will free up a lot of space on your hard drive and rearrange the files so that your applications run faster.
8.Always make two partitions in your hard drive. Install all large Softwares (like PSP, Photoshop, 3DS Max etc) in the second partition. Windows uses all the available empty space in C drive as virtual memory when your Computer RAM is full. Keep the C Drive as empty as possible.
9.When installing new Softwares disable the option of having a tray icon. The tray icons use up available RAM, and also slow down the booting of your PC. Also disable the option of starting the application automatically when the PC boots. You can disable these options later on also from the Tools or preferences menu in your application.
10. Protect your PC from dust. Dust causes the CPU cooling fan to jam and slow down thereby gradually heating your CPU and affecting the processing speed. Use compressed air to blow out any dust from the CPU. Never use vacuum. RAM IS THE WORKING AREA (DESKTOP) OF THE CPU, KEEP IT AS EMPTY AND UNCLUTTERED AS POSSIBLE!

- Simple (and free) ways how to speed up your computer:
Tip: Disable the XP loading screen
To speed up booting your computer process slightly, disable the Windows XP loading screen. This can be done very easy:
- Open the MSCONFIG utility (Open Start\Run and type msconfig)
- Select the boot.ini tab
- Check the /NOGUIBOOT option. When you boot (start) your PC, you will see a black screen in between POST and the welcome screen from now on.

Tip: Check your hard drives with scandisk
With time, tons of small data problems and physical problems can develop and slow down the performance of your hard drive. While defragmenting the drive can help restore much of the performance you might have lost, there are other issues such as lost clusters which the defragmentation utility cannot fix.
Because of this, it is a good idea to run XP's error checking utility once in a while. This utility scans your disks for errors and optionally attempt to correct them.

- Open My computer
- Right click the hard disk you wanna scan and select Properties from the menu
- Choose the Tools tab and under Error checking click the Check now… button.
- Check both options. You will need to restart the computer to do the full disk check.

Your disk will be fully checked for errors upon reboot, but this can take quite a while.
