Does your desktop PC get slow at time, and that makes you frustrated? it is time that you become a system Mechanic yourself!!! This article should help you for the same.(this article is not for new PC users)

There are two major reasons why the PC may be slow,one is due to software reason,the other is due to hardware reasons.First we'll discuss about the software reasons that may be slowing down your computer;Consider the following to tackle software problems;

There might be unwanted clutter in your computer( unwanted/garbage data) clean it right away.

• If you are advance user, do it yourself by deleting the contents of prefetch,local temp and windows temp folder.
• Or you can use any freeware from internet.I
• In the Run command window(go to start>run) and type  prefetch  or  temp  or  %temp%  these are the three folders that will contain most of the active clutter in PC.

• You should try to clean your system registry,unfortunately you can't do it manually, you've to use aany software that assists in repairing/optimising registry.I would suggest downloading freeware from www.softpedia.com

• If you are running lots of games or graphical applications,you must try and increase the system paging.This is done by using the system properties window.
• Press windows key and pause together or right click my computer ands select properties.In the window that appears,Select the advance tab,in that sellect the settings button under performance,again select advance in the dialog box that apppears,there you'll find the option to set the paging.

• Try to clean up drive, check for errors and defragment drives once every two months.
• This is done by selecting the property of any drive and go to tools tab there you'll find the options to select defragmentation or check errors.

• Check if there are any conflict with the driver files and hardware, since a faulty driver can sometimes slow down the computer.
• This can be done using utility softwares that are availabe in internet,there are some online services too.

• Always have an active virus detection and cleaning software.

• Unwanted startup programs both system and general services sometimes cause the PC to slow down.Get a software that could solve this problem.
• Type msconfig in run prompt(go to start>run),in the dialog box that appears select the startup tab and do the necessary changes.(in the image you can see that only necessary startup are selected)

• Unwanted graphical applications like TSR programs,desktop enhancements,themes, desktop widgets,etc can be slowing down the PC.So uninstall the related unwanted software.

• The PC hardware problems that might be causing the PC to slow down may be due to overheating of the processor-solution is to have the PC in a well air circulated room.Also accumulated dust on ICs and on the sink(the thing above the processor) can contribute to increase in temperature of processor.

• problems with the processor can also cause the trouble-in which case,you've to consult an aurthorised service engineer
