I am posting a summary checklist of general steps you can take to resolve this issue, and briefly discussing the three most common causes : malware, uncontrolled applications, and insufficient maintenance, because many readers write about their computer responding slowly.
Possibly the most important contributor to a poorly performing computer is malware. Usually this is associated with downloading an application that includes spyware, by not having browser security settings large enough, by carelessly downloading P2P files, or by failing to install security patches regularly.
Step 1. Revise the definitions of your anti-virus and operate a full scan of your hard disk drive in Safe Mode. Solve any unfixable issues. Note that some infections require additional steps until they could be removed; usually a web search will find specific directions or a special removal tool. If you can’t find a answer, use the BC forums to request help.
Step 2. If the sluggishness is surprising, and you have recently downloaded an application, the problem might live there. Check this by completely eliminating it. A smart user will usually perform a web search about the program before downloading it because in most instances, any possible trouble with malware or inferior performance will have surfaced.
Action 3. Adware and Spyware can drastically impact your computer’s functionality, and these are all over the World wide web.
Update the explanations of your anti-spyware applications and scan your hard drives in Safe Mode. Seasoned customers will consistently operate 2 or 3 of the applications, because each business has its own standards for what constitutes spyware and will only search against their own established. (A set of quite good, free antispyware applications is given by BC). Again, resolve any open issues before proceeding to the next step.
Stage 4. Review applications that self-launch on startup. You pc may be a battleground for your consideration. Many programs, for example, install a quick-start feature that allows them to be opened immediately; other programs will include an automated update feature that demands them to be working in the background. Each of these decreases your launching Windows and each needs a little bit of sources while your personal computer is running.
If, like, you have Spybot Search and Destroy, you can use its startup tool that lists startups and lets you to turn off any you usually do not need. In case you are unsure about what can be safely deleted, remember that BC maintains a very complete Startup Database that contains information about whether the questioned item is required, discretionary, or unnecessary.
At the same time, remember that all those symbols in your Desktop also take a small amount of trunk time to set themselves.
Absence of Maintenance
Step 5. Clean-up your hard drive (preparation for Stage 7). Delete unused applications and transfer old files to a CD. Unplayed games, tons of family images, zipped files that you have already opened, applications you have not found in two years, software for the old printer you threw away last year—these are some types of files you can delete.
(Note for sophisticated users: some specialists would include the additional maintenance step of cleaning the Windows registry, and you’ll find plenty of apps to help do this. For the most part, registry maintenance won’t make a significant difference, and unless you’re really comfortable with Windows, and cautiously make backups of-the registry, you may do significant damage by creating registry modifications, so this measure is not contained
Stage 6. Run scandisk / checkdisk in Safe Mode. Have it mend 1501 (0x5dd).
Step 7. Defragment your personal computer.
Hopefully, now that you have have finished, you will see a noticeable enhancement in pc operation.
