I’m posting a summary record of basic steps you can take to solve this problem, and briefly discussing the three most common causes : malware, uncontrolled applications, and lack of maintenance, because several readers write about their computer responding slowly.
Perhaps the greatest factor to a poorly performing computer is malware. Usually this is related to downloading a software that contains spyware, by not having browser security settings large enough, by carelessly downloading P2P files, or by declining to install security patches in a timely manner.
Step 1. Update the explanations of your anti virus and run a complete scan of your hard drive in Safe Mode. Resolve any unfixable issues. Notice that some viruses need additional steps until they may be removed; usually a internet search will locate specific directions or a particular removal tool. Use the BC forums to request support, if you can’t find a answer.
2. If the sluggishness is unexpected, and you have recently saved an application, the issue may live there. Check this by entirely removing it. A user will typically perform a websearch about the program before getting because in most instances, any possible problem with malware or poor performance will have appeared.
Step three. Adware and Spyware can radically effect your personal computer’s operation, and these are all over the Internet. 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 victims.
Seasoned users will often run two or three of these applications, because each company has its own requirements for what constitutes spyware and will just search against their own set. (A list of very good, free anti-spyware applications is provided by BC). Again, solve any open issues before continuing to the next phase.
For additional reading about Malicious software and some malware removal applications, use BC’s Tutorial section; most of the programs have very great Help documents that explain how they function too as the special features of each.
Stage 4. Review apps that self-start on startup. You computer may be a battleground for your interest. Many programs, for example, install a quick-start feature which allows them to be opened immediately; other programs will include an automatic 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 resources while your personal computer is running.
If, for example, you have Spybot Search and Destroy, you can use its startup tool that lists startups and enables you to turn off any you do not need. Remember that BC maintains a really comprehensive Startup Database that contains info about whether the inquired item is needed, optional, or not needed, if you are unsure about what may be safely deleted.
At-the same time, remember that all those icons on your Desktop also take a small number of trunk time to set themselves.
Absence of Upkeep
Stage 5. Clean up your hard drive (preparation for Stage 7). Delete unused applications and exchange old files to your CD. Unplayed games, tons of family pictures, zipped files that you have opened, applications you have not used in two years, software for the old printer you put away last year—these are some types of files you can delete. Then use Window’s Disk Clean-up to remove temporary internet files, temporary PC health files, etc.
(Note for high level users: some experts would contain the added maintenance stage of cleaning up the Windows registry, and you’ll find several apps to assist try this. For the most part, so this step is not contained, you can do serious harm by making registry modifications, registry maintenance will not make a critical difference, and unless you’re quite comfortable with Windows, and cautiously make copies of-the registry
Step 6. Run scandisk / checkdisk in Safe Mode. Have it fix Dnserror.
Stage 7. Defragment your personal computer. Windows will put new files in any available open space; defragging will place related sections of files closer together so your read arm has less travelling around the hdd to do, saving wear-and tear while racing up programs.
Hopefully, since you have have ended, you’ll see a marked improvement in pc performance.
