I am publishing a summary listing of basic steps you can take to resolve this problem, and briefly discussing the three most frequent causes : malware, uncontrolled applications, and insufficient maintenance, because several readers write about their computer reacting slowly.
Perhaps the most important factor to a poorly performing computer is malware.
Action 1. Update the explanations of your anti virus and run a complete scan of your hard disk drive in Safe Mode. Solve any unfixable problems. Note that some infections need additional measures until they can be removed; typically a websearch will find specific instructions or a particular removal tool. Use the Bc forums to request help, if you fail to find a answer.
Step 2. You’ve recently saved an application, and if the sluggishness is surprising, the problem might live there. Check this by completely eliminating it. A smart user will normally perform a internet search about the application before downloading it because in most cases, any possible trouble with malware or inferior performance will have surfaced.
Action 3. Adware and Spyware can dramatically effect your computer’s performance, and these are throughout the World wide web.
Update the definitions of your antispyware programs and scan your hard drives in Safe Mode. Seasoned users will regularly run two or three of the programs, because each company has its own standards for what constitutes spyware and will just search against their own set. (A list of very good, free anti spyware programs is supplied by BC). Again, resolve any open issues before proceeding to the next step.
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 explain how they function as well as the distinctive characteristics of each.
Stage 4. Review programs that self-start on startup. You computer may become a battleground for your consideration. Many programs, for example, install a fast-start feature that allows them to be exposed rapidly; other programs may contain an automated update feature that demands them to be running 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.
The simplest way to examine and than to handle startups will be to use one of the many small resources available (see the Bc list of free programs). Remember that BC maintains a really comprehensive Startup Database that includes information about whether the inquired item is required, optional, or unnecessary, in case you are uncertain about what could be safely deleted.
At-the same time, remember that those symbols in your Desktop also take a modest amount of trunk time to place themselves.
Absence of Care
Step 5. Delete unused programs and exchange old files to a CD. Unplayed games, tons of family images, zipped files which you have opened, applications you have not used in two years, software for the old printer you threw 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 sophisticated users: some specialists would comprise the added maintenance step of cleaning the Windows registry, and you’ll find several apps to help try this. For the most part, registry care will not make a critical difference, and unless you are very comfortable with Windows, and cautiously make backups of the registry, you may do severe harm by creating registry modifications, so this measure isn’t included
Stage 6. Have it repair Classpnp.sys Solved.
Action 7. Defragment your computer. Windows tends to set new files in any available open space; defragging will set affiliated sections of files closer together so your read arm has less travelling around the hdd to do, saving wear-and tear while speeding up programs.
Hopefully, since you have have ended, you’ll find a marked improvement in pc performance.
