Your computer is designed to perform effectively throughout its lifetime. Rarely does this happen, because the endless practice of installation and uninstallation of programs reduces the degree of compatibility of different programs with the operating system. To speed up slow computer there is dire need to create more space in the hard drive to avoid memory being chewed up by the unwanted programs. The speed of execution of any input depends with the processor in place and the capacity of the RAM. Upgrading the RAM could be the only way out if you wish to multitask and listen to some music in the background. You can also free more space in the drive by deleting unnecessary files. Most of the installed programs chew up a lot of memory and yet they are rarely used. These programs should be deleted with immediate effect if speed is desired.
There are some computers which are slow not because they are running out of space but because they are infected by viruses. You should note that there are some viruses that are very stubborn and multiply very fast. To speed up slow computer of such a kind, you should install an up-to-date antivirus and perform a quick scan to elicit all the worms. An option is always provided as to whether you want to delete the file or you want to move it to the quarantine. Some computers are highly infected to a point of clashing and they may demand formatting the hard drive to delete all the files. After formatting, an antivirus should be installed immediately and a quick scan performed. At this point in life, your antivirus should be able to identify any infections that may have found access to your computer during the formatting process.
You can regularly clean the desktop as one of the effective ways to speed up slow computer. A desktop clean up wizard can be run to delete all the unnecessary items you may have stored in the desktop. A computer connected to the internet is more likely to slow down because every time a new page is opened, the computer tries to access the previous page. These download files should be deleted to free more space. There are also some programs that tend to start up anytime you start your computer. these programs should be disabled to allow important programs to start solely. It is a great way to speed the performance of a slow computer. Installed game programs chew up a lot of memory and may cause your computer to hang up or freeze.
Defragmenting the hard disk is another effective way to speed up slow computer. there are different programs available online and can be used to perform the operation. The aim is to remove all the fragmented files and create more space in the drive. Cleaning of computer is yet another tip to do away with a slow computer. Cleaning is more than just dusting the monitor every morning you step in that office. The CPU needs to be regularly dusted to remove all the dust that may clog the vents of the fan. The fan is the cooling system of the computer and needs to be dust-free to avoid heating and freezing of the computer. A dust blower can be used to remove all the dust while a soft cloth can be used to wipe some parts. However, you should not touch any internal part of your computer with bare hands and when the machine is connected to the power. When the above is followed, then you can sit back and let your machine do the work for you.

I find cleaning my computer of all its dust often makes a big difference. I also use a fully automatic defragger that goes to work as soon as fragmentation takes place. Makes a huge difference on my workstation. The in-built defragger is no good at work.
