Hey folks,
       you all must have been thinking that your lovely computer which has a great configuration slows down very soon after installing a fresh copy of Operating  System, and again without willing to format it you have to format your computer for better performance but it seems to be of no use after couple of days. And yes formatting your computer several times also affects performance of your Hard Disk Drive (HDD).
But now, no need to worry any more, i m here with this very easy  but really helpful trick to keep your computers performance up every time. and increase your computer speed upto 60% more.
Here we go...........

1. Let your PC boot up completely before opening any applications. 
(your computer has to load many programs and services that are setup in 
start-uptask of the computer which takes some time to load. and opening any
other app during this time makes your computer to respond slowly.)

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. 
(Wallpaper makes your desktop look nice and attractive but it reserves 
some part your RAM and makes your computer performance slow down to 
some extent.) 
If possible try to avoid use of any wallpaper.

4. Do not clutter your Desktop with a lot of shortcuts. Each shortcut on 
   the desktop uses up to 500 bytes of RAM.
(Try to use as less shortcut and icons on your desktop as possible.)

5. Empty the recycle bin regularly.The files are not really deleted from your 
   hard drive until you empty the recycle bin.
(Try to use SHIFT + DELETE to delete a file directly from the Hard drive.)

6. Delete the temporary files regularly.
(To delete Temporary file open run box (WIN+R) and type "%temp%" without any 
qoutes click on OK a window will appear select all the files and delete them, 
as these files are of no use.)

7. Defragment your hard drive at least once a month.
(This will free up a lot of space on your hard drive, by filling the empty
space left by deleted files, and arranges current files in right indexed 
order that helps in faster execution of programs and Operating system files.)

8. Always make two partitions for Operating system in your hard drive.
(Install all large Softwares in the second partition. Windows uses all the 
available empty space in C drive as virtual memory when your Computer RAM 
is fully occupied by the Operating system and other programs. Keep the "C" 
Drive as empty as possible.)

9. When installing new Softwares disable the option of having a tray icons 
   and toolbars for browsers.
(The tray icons use up available RAM, and also slow down the booting of your 
PC. while toolbars comsume some amount of bandwith that you use while surfing
internet. Also disable the option of starting the application automatically 
when the PC boots.)

10. Protect your computer from dust.
(Dust is the biggest enemie of your computer.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.)
