I am posting a summary checklist of basic things you can do to resolve this problem, and briefly discussing the three most common causes : malware, uncontrolled applications, and insufficient maintenance, because several readers come up with their computer responding slowly.
Possibly the greatest contributor to a poorly performing computer is malware. Generally this is related to downloading a software that includes spyware, by not having browser security options high enough, by carelessly downloading P2P files, or by declining to install security patches in a timely manner.
Action 1. Revise the explanations 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 extra measures before they could be removed; usually a websearch will find specific directions or a special removal tool. Use the BC forums to obtain assistance, if you can’t find a solution.
Step Two. If the sluggishness is unanticipated, and you’ve recently downloaded an application, the problem might live there. Check this by fully removing it. A user will generally perform a websearch about the program before downloading it because in most cases, any possible issue with malware or poor performance will have appeared.
Stage 3. Adware and Spyware can radically effect your personal computer’s performance, and these are throughout the World wide web.
Update the definitions of your antispyware programs and check your hard drives in Safe Mode. Seasoned users will consistently operate several of the programs, because each company has its own standards for what constitutes spyware and will only search against their own established. (A listing of very great, free anti-spyware applications is given by BC). Again, resolve any open issues before continuing to the next phase.
Step 4. Review programs that self-launch on startup. You computer may be a battleground for your attention. Many programs, for instance, install a rapid-start feature which enables them to be exposed fast; other programs may contain an automatic update feature that requires them to be operating in the background. Your launching Windows are slowed down by each of these and each needs a little bit of sources while your computer is running.
You can use its startup tool that lists startups and lets you to turn off any you do not need, if, for example, you have Spybot Search and Destroy. If you’re uncertain about what could be safely removed, remember that BC maintains a very comprehensive Startup Database that includes information about whether the questioned item is needed, optional, or unnecessary.
At the same time, remember that all those icons in your Background also take a modest amount of boot time to put themselves.
Absence of Upkeep
Step 5. Cleanup your hard drive (preparation for Action 7). Delete unused applications and transfer old files to a CD. Unplayed games, tons of family images, zipped files that you have opened, applications you haven’t used in two years, software for the old printer you threw away last year—these are some examples of files you can delete.
(Note for high level users: some specialists would contain the added upkeep stage of cleaning the Windows registry, and there are plenty of apps to assist do that. For the most part, registry care will not make a significant difference, and unless you’re really comfortable with Windows, and cautiously make copies of the registry, you may do significant damage by creating registry changes, so this step is not included
Step 6. Run scandisk / checkdisk in Safe Mode. Have it mend 0xc00021a..
Stage 7. Defragment your computer.
Hopefully, now that you have have concluded, you’ll find a noticeable enhancement in pc operation.
