Delete unwanted files

Delete any unwanted files and folders that you don’t need. These can be files you downloaded from the internet or duplicates that you have on your computer. There might be video or music files that are duplicates or that you don’t need, delete them then empty your recycle bin. Doing this will create more space on your hard drive hence making it faster.

Uninstall programs you don’t use

If you have had your computer for a long time then there might be a lot of programs that you don’t need anymore. Go through your programs and find the ones you don’t need and uninstall them. 3D games usually take up a lot of space so if you have any that you don’t need, clean em up. To uninstall programs go to control panel then click add and remove programs.

Scan for viruses and spywares

There are viruses and spywares that usually run on the task bar taking a lot of CPU and memory power. Download a free antivirus like AVG or download a trial version of Kaspersky and do a full scan on your computer for any viruses. If you find any, remove them then restart your computer.

Defragment Disk

Defragmenting helps organize your hard drive so that the files can accessed easily and faster. Do this at least every 2 to 4 months to keep your computer fast. To do it go to Start – All Programs – Accessories – System Tools – Disk Defragmenter.

Increase ram

If none of this works then this is the best alternative. Increasing RAM size will help you a lot especially if you have windows XP and above. To see how much memory you have, press the windows key and pause key at the same time.
