I am posting a summary listing of general things you can do to resolve this issue, and briefly discussing the three most common causes : malware, uncontrolled applications, and lack of care, because many readers come up with their computer responding slowly.
Maybe the greatest contributor to a badly performing computer is malware.
Stage 1. Update the explanations of your antivirus and run a full scan of your hard disk drive in Safe Mode. Solve any unfixable problems. Note that some infections require extra steps before they can be removed; ordinarily a websearch will locate specific instructions or a special removal tool. Use the Bc forums to request assistance, if you cannot find a answer.
2. If the slowness is unexpected, and you’ve recently saved an application, the issue may dwell there. Check this by completely removing it. A wise user will normally perform a web search about the application before installing because in most instances, any possible issue with malware or poor performance will have surfaced.
Step 3. Adware and Spyware can dramatically effect your computer’s operation, and these are all over the Net. A very recent research indicated that one out of every 20 executable files on Web sites is spyware, and 1 in 25 domains include at least one bit of spyware waiting for sufferers.
Update the definitions of your anti spyware applications and scan your hard drives in Safe Mode. Experienced customers will frequently run several of the applications, because each business has its own standards for what constitutes spyware and will just search against their own established. (A listing of quite great, free anti-spyware applications is provided by BC). Again, resolve any open issues before proceeding to the next step.
For additional reading about Malware and some malware removal applications, use BC’s Tutorial section; most of the programs have really great Help documents that explain how they work also as the unique attributes of each.
Step 4. Evaluation apps that self-launch on startup. You pc can become a arena for your interest. Many programs, for example, install a quick-start feature that permits them to be opened immediately; other programs may contain an automatic update feature that requires them to be running in the background. Your launching Windows are slowed down by each of these and each requires a small bit of resources while your computer is running.
You can use its startup tool that lists startups and allows you to show off any you usually do not need, if, for example, you have Spybot Search and Destroy. In case you are unsure about what may be safely deleted, remember that BC maintains a quite complete Startup Database that includes info about whether the questioned item is needed, discretionary, or unnecessary.
At the same time, remember that those symbols on your Desktop also take a modest amount of boot time to set themselves.
Lack of Maintenance
Stage 5. Clean up your hard drive (preparation for Step 7). Delete unused programs and exchange old files into a CD. Unplayed games, tons of family pictures, zipped files which you have already opened, applications you have not used in two years, software for the old printer you put away last year—these are a few types of files you can delete. Then use Window’s Disk Clean-up to delete temporary internet files, temporary PC health files, etc.
(Note for higher level users: some specialists would include the additional upkeep stage of cleaning the Windows registry, and you will find plenty of applications to assist try this. For the most part, registry care won’t make a major difference, and unless you are quite comfortable with Windows, and carefully make backups of the registry, you may do serious harm by making registry changes, so this step isn’t included
Stage 6. Run scandisk / checkdisk in Safe Mode. Have it mend Bootable System32.
Action 7. Defragment your pc.
Hopefully, now that you have have ended, you will see a marked enhancement in pc performance.
