TOP ten Tips to increase System Speed

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!

Increase your RAM and so system speed

1). Start any application, say Word. Open some large documents.
2). Press CTRL+ SHIFT+ESC to open Windows Task Manager and click Processes tab and sort the list in descending order on Mem Usage. You will notice that WINWORD.EXE will be somewhere at the top, using multiple MBs of memory.
3). Now switch to Word and simply minimize it. (Don't use the Minimize All Windows option of the task bar).
4). Now go back to the Windows Task Manager and see where WINWORD.EXE is listed. Most probably you will not find it at the top. You will typically have to scroll to the bottom of the list to find Word. Now check out the amount of RAM it is using. Surprised? The memory utilization has reduced by a huge amount.
5). Minimize each application that you are currently not working on by clicking on the Minimize button & you can increase the amount of available RAM by a substantial margin. Depending upon the number and type of applications you use together, the difference can be as much as 50 percent of extra RAM. In any multitasking system, minimizing an application means that it won't be utilized by the user right now. Therefore, the OS automatically makes the application use virtual memory & keeps bare minimum amounts of the code in physical RAM.
