I am submitting a summary checklist of basic steps you can take to resolve this issue, and briefly discussing the three most common causes : malware, uncontrolled applications, and insufficient care, because several readers write about their computer responding slowly.
Perhaps the greatest contributor to a badly performing computer is malware.
Step 1. Update the definitions of your anti virus and run a full scan of your hard disk drive in Safe Mode. Resolve any unfixable issues. Note that some infections require extra steps before they may be removed; typically a web search will find specific instructions or a particular removal tool. Use the Bc forums to obtain support, if you cannot find a answer.
2. You’ve recently saved an application, and if the sluggishness is sudden, the issue may reside there. Test this by totally eliminating it. A wise user will typically perform a websearch about the application before installing because in most instances, any potential issue with malware or inferior performance will have surfaced.
Step three. Adware and Spyware can drastically impact your computer’s performance, and these are around the Internet.
Update the explanations of your anti-spyware programs and scan your hard drives in Safe Mode. Seasoned users will frequently run 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 list of really good, free anti-spyware programs is given by BC). Again, solve any open issues before continuing to the next phase.
For further reading about Malware and some malware removal applications, use BC’s Tutorial section; most of the applications have quite great Help documents that clarify how they work also as the unique characteristics of each.
Stage 4. Evaluation applications that self-launching on startup. You computer can be a battleground for your attention. Many programs, for example, install a rapid-launch feature which enables them to be opened fast; other programs may include 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 small bit of resources while your 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 want. Remember that BC maintains a very comprehensive Startup Database that includes info about whether the item is required, optional, or unnecessary, if you’re unsure about what could be safely deleted.
At-the same time, remember that those icons on your Background also take a modest amount of boot time to put themselves.
Absence of Maintenance
Step 5. Cleanup your hard drive (preparation for Action 7). Delete unused applications and transfer old files into a CD. Unplayed games, lots of family images, zipped files which you have already opened, applications you haven’t used in two years, software for that old printer you put away last year—these are some types of files you can delete.
(Note for advanced level users: some specialists would comprise the additional care stage of cleaning the Windows registry, and you’ll find several apps to help do this. For the most part, registry care will not make a critical difference, and unless you are really comfortable with Windows, and carefully make copies of-the registry, you can do significant damage by making registry changes, so this step isn’t contained
Stage 6. Run scandisk / checkdisk in Safe Mode. Have it fix Active X Security Settings.
Stage 7. Defragment your personal computer.
Hopefully, now that you have have finished, you’ll see a noticeable improvement in computer functionality.
