Does your computer respond like a snail? Does it take forever to start a program? Are you like many people who are tired of having to spend a long time trying to get something done? If yes, then you are lucky, because I am about to present very simple yet very effective method of speeding up your computer. The three main reasons why computers slow down are: - There is no space in the Hard disk - Your computer is infected with virus or spyware - The registry of your computer is overcrowded with missing or invalid entries. If hard disk space is a problem, then you need to uninstall some unused programs and/or delete some large files. If you have a lot of music or video files, it's a good idea to go through them and remove those that you no longer want. But before you even start deleting any files, you must first find out whether the hard disk space is the cause of computer slow down. Go to "My computer" and click on each of your drives and look on the left to see if there is enough space. Usually, a computer runs fine if you have at least 100 Mb space in the drive that contains the Windows installation files (in most cases it is C://). You computer can also be slowed down by a virus or a spyware. If this is the cause you must remove the virus or spyware. Start your antivirus program and run a full system scan. The program will go through each and every file in your system to find out if there is a virus or a malware hiding there. If you don't have a antivirus or antispyware program, go to http://spywareshoot.info/ to get a free one. Another reason why most computers are slow is a messy registry. A registry is a log book of the Windows system, and the computer slows down considerably if the registry contains a lot of unnecessary or invalid entries. This is because the operating system wastes time going through unnecessary files, and therefore keeps the important programs waiting for their turn. This is why it is important to clean and repair your computers registry every once in a while. The best way to do this is by using a registry cleaner. If you don't have one already, you can get a free one from http://registry-booster.info/ Follow these steps and I assure you that your computer will run considerably faster and you can get your work done on time.
