How to clean a computer

1. Prevent programs from automatically running when you start up your computer.

This is one of the main reasons computers can run slowly. Many computers automatically run programs in the background, which uses your computer’s memory and slows your computer down. While some programs, such as antivirus and firewall software, should be allowed to run automatically, you can close others (such as iTunes or Microsoft Office) until you actually need them.

2. Delete/uninstall programs you don’t use.

Many new computers come with pre-installed programs that take up space and run background processes automatically. Go into your control panel and uninstall the programs you don’t need, being careful to keep the ones you do need.

3. Clean up hard disk space.

Check how much free space you have on your computer. If you have less than 15% free space, your computer could slow down. Delete old programs and files you don’t need or compress some of your files (especially large ones). Note that if your computer is running slowly and storage isn’t full, your operating system may be having problems.

4. Save old pictures or videos to the cloud or external drive.

This frees up a lot of memory space, which will also speed up your computer. Keeping them in the cloud or on an external drive is also a nice way to back up those old family photos that you don’t want to lose.

5. Run a disk cleanup or repair.

Your computer generates a lot of temporary files each time you boot up and/or use applications. These temporary files, such as Internet history, cookies, and caches, take up a considerable amount of space on your hard disk, further slowing down your system. A disk cleanup/repair can clean up hundreds of megabytes by deleting temporary files, unnecessary system files, and even just emptying your recycling bin.

6. Changing the power plan of your desktop computer to High Performance.

Computers have different power plans (usually Balance, Power Saver, and High Performance) to control how the computer uses power. Some settings optimize battery life by lowering performance, but High Performance will increase the speed and performance of the computer. Note that this will only work on a desktop, as the HighPerformance setting on a laptop will drain the battery.

7. Make sure you have anti-virus, spyware scanner, and anti-malware installed.

Your computer will be able to run faster if it’s not spending time trying to manage bugs and viruses. This is also an added layer of protection to keep your computer safe!

8. Run a disk defragment to optimize your hard drive’s efficiency.

When data is fragmented, your computer has to search for the fragments of files that could be spread throughout your hard drive. Defragmenting will organize your data and free up space so your computer can access data faster.

9.Add more RAM to your computer.

RAM is temporary storage memory used by your PC to run programs. The more programs you use, the more RAM you need; and if you don’t have enough, your computer will slow down. You can easily add more RAM by buying an extra memory stick, but you can also replace or buy a completely new RAM if necessary.

10.Update your computer’s software.

Software updates will fix bugs and glitches that make your computer run slower. To check if your current software is up-to-date on Windows, click the Start Button > All Programs > Windows Update > Check for Updates. On a Mac, go to Apps under the Apple icon menu and click on About this Mac.
