Computer Performance Booster Tips

Dear visitor what is your computer speed ? did you ever think about that sometimes it may be higher than of what your computer now have, just like our vehicles if you didn't give proper maintenance it will show it's anger,
In case of our computers also if you didn't give proper settings it will not give you that performance that it actually have.

Here is some tips or some tricks that increase your computer's performance and speed, now everything will get faster.



1.Delete temporary files in the computer.

When the computer performs many tasks like installation of software, software updates and many things like this it will keep a temporary copy or a temporary disk area to perform that particular operation actually these files are not needed to the system when the operation is over. some software automatically deletes these files otherwise it will be a garbage item in our system it reduces the available disk space and reduces computing capacity so delete any temporary files if any.(Start->run->temp and press ok)

   
2.Delete User temporary files.

This is also a temporary file directory where temporary files corresponding to the user are stored delete those files also(Start->run->%temp% and press ok)

3.Delete recent files accessed.

This directory only consist of shortcuts of the recently accessed files.
(Start->run->recent)

4.Perform Disk Cleanup.


Disk cleanup is a utility which cleans up unnecessary files from the drive.
(Start->programs->Accessories->System tools->Disk cleanup) choose all unwanted files and click ok.


5.Perform Disk De-fragmentation.

Disk De fragmentation is a tool which arranges the fragmented files in the disk. when ever we write files into the hard disk it is stored in different locations in the disk, by De fragmenting these files are grouped together and it enables fast access of data from the hard disk.Rather than getting free memory this is a good practice to do De fragmentation.


6.Changing the Folder options.

Goto control panel->folder options.
a)In genaral tab deselect 'show common tasks in folders' and set 'use windows classic folders option'.
b)In view tab deselect 'Automatically search for network folders and printers'.


7.Changing Advanced settings of 'my computer'.

Goto my computer right click and select properties and select advanced and click on performance settings
in that new window deselect items except the following.
i)smooth edges of screen fonts.
ii)smooth scroll list box
iii)use drop shadow for icon labels on the desktop.
iv)use visual style on windows and buttons.
