How do you clean a slow-running computer in six steps?

To clean a slow running computer in six steps, clear up used space on the storage drive and eliminate software that's causing the computer to slow down. Deal with start-up programs and Internet files before cleaning registries and de-fragmenting the drive.

1. Delete useless Internet browser files

   Open your Internet browser, and enter the Settings options. There is an option which allows you to delete your cookies, cache memory and browser history. Clear these to eliminate a big chunk of rarely used data on the computer's hard drive.

2. Disable start-up programs

   When the computer boots up, it must run through the algorithms of start-up programs. Disable unnecessary start-up programs which cause your booting process to slow down and can become a constant drain on your PC.

3. Uninstall useless software

   Uninstall useless software that is occupying space and memory without providing a benefit to you. To do this, access the Control Panel option, then access the Uninstall Programs option to get a view of all the programs installed on your system

4. Clear memory and storage

   Transfer or delete files from your PC. Keep a significant amount of space free on your PC to lessen the burden on your system. This enables the computer to reduce the cycles it has to run through to get to a file.

5. Clean registries

   Clean your windows registries by using a trusted registry optimizer. Look for software that can eliminate entries without harming the computer in any way.

6. Defragment the disk

   Defragmenting gathers spread-out system data to allow faster access. The computer often fragments storage with chunks of data, slowing down data retrieval.
