I am posting a summary checklist of basic steps you can take to resolve this problem, 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.
Perhaps the most important factor to a poorly performing computer is malware. Usually this is associated with downloading a software that contains spyware, by not having browser security settings large enough, by carelessly downloading P2P files, or by failing to install security patches in a timely manner.
Step 1. Revise the explanations of your anti-virus and run a complete scan of your hard drive in Safe Mode. Solve any unfixable issues. Notice that some viruses need additional measures before they could be removed; ordinarily a websearch will locate specific instructions or a special removal tool. Use the Bc forums to request support, if you cannot find a solution.
Step Two. You have recently saved an application, and if the slowness is unanticipated, the problem may rest there. Test this by entirely removing it. A user will normally perform a web search about the application before installing because in most cases, any possible issue with malware or poor performance will have surfaced.
Step three. Adware and Spyware can drastically effect your personal computer’s performance, and these are around the World wide web. A very recent study showed that one out-of every 20 executable files on Web sites is spyware, and 1 in 25 domains include at least one piece of spyware waiting for victims.
Revise the explanations of your antispyware programs and check your hard drives in Safe Mode. Seasoned users will consistently operate two or three of the programs, because each company has its own standards for what constitutes spyware and will simply search against their own set. (A set of very good, free anti-spyware programs is provided by BC). Again, resolve any open issues before continuing to the next phase.
Step 4. Review apps that self-launch on startup. You computer may be a battleground for your attention. Many programs, for example, install a rapid-launch feature which enables them to be opened promptly; other programs will 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 requires a small bit of sources while your computer is running.
Remember that BC maintains a quite comprehensive Startup Database that contains info about whether the questioned item is needed, elective, or not needed, if you’re unsure about what may be safely removed.
At the same time, remember that all those symbols in your Desktop also take a small amount of boot time to set themselves.
Lack of Maintenance
Step 5. Cleanup your hard drive (preparation for Action 7). Delete unused applications and move old files into 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 a few examples of files you can delete.
(Note for sophisticated users: some experts would contain the additional maintenance step of cleaning up the Windows registry, and you’ll find several applications to help try this. For the most part, so this step isn’t included, you may do significant damage by making registry modifications, registry care will not make a critical difference, and unless you’re quite comfy with Windows, and cautiously make backups of-the registry
Action 6. Run scandisk / checkdisk in Safe Mode. Have it repair Error770.
Step 7. Defragment your computer.
Hopefully, since you have have ended, you will find a marked improvement in pc operation.
