Possibly the most important factor to a badly performing computer is malware.
Stage 1. Update the definitions of your anti-virus and run a complete scan of your hard drive in Safe Mode. Solve any unfixable problems. Notice that some infections need extra measures before they may be removed; usually a websearch will find specific directions or a special removal tool. If you fail to find a solution, use the BC forums to request help.
Step 2. You have recently downloaded an application, and if the slowness is unexpected, the problem might rest there. Test this by completely eliminating it. A sensible user will usually perform a websearch about the application before downloading it because in most cases, any possible trouble with malware or poor performance will have surfaced.
Step three. Adware and Spyware can radically effect your computer’s functionality, and these are all over the Web. A very recent research indicated that one out of every 20 executable files on Websites is spyware, and 1 in 25 domains comprise at least one bit of spyware waiting for victims.
Revise the definitions of your anti spyware programs and check your hard drives in Safe Mode. Experienced users will regularly operate 2 or 3 of the programs, because each business has its own requirements for what constitutes spyware and will just search against their own set. (A record of really great, free antispyware applications is supplied by BC). Again, resolve any open issues before proceeding to the next phase.
Stage 4. Evaluation apps that self-launch on startup. You pc may become a battleground for your interest. Many programs, for instance, install a fast-launch feature which enables them to be opened immediately; other programs may include an automated update feature that requires them to be working in the background. Each of these decreases your launch Windows and each needs a little bit of resources while your computer is running.
Remember that BC maintains a quite comprehensive Startup Database that contains information about whether the item is required, elective, or unnecessary, in case you are unsure about what could be safely deleted.
At the same time, remember that all those symbols in your Background also take a modest number of boot time to set themselves.
Lack of Maintenance
Stage 5. Clean-up your hard drive (preparation for Step 7). Delete unused programs and move old files to your CD. Unplayed games, tons of family images, zipped files which you have previously opened, applications you haven’t used in two years, software for the old printer you put away last year—these are some examples of files you can delete. Then use Window’s Disk Cleanup to remove temporary internet files, temporary PC health files, etc.
(Note for advanced level users: some experts would contain the added care step of cleaning the Windows registry, and you’ll find several apps to help do that. For the most part, registry care won’t make a major difference, and unless you’re very comfy with Windows, and carefully make copies of the registry, you may do severe damage by making registry modifications, so this step is not included
Stage 6. Run scandisk / checkdisk in Safe Mode. Have it fix Runtime Error Pure Virtual Function Call.
Step 7. Defragment your computer. Windows tends to put new documents in any available open space; defragging will place associated sections of files closer together therefore your read arm has less travelling around the hdd to do, saving wear and tear while racing up programs.
Hopefully, now that you have have concluded, you’ll see a noticeable improvement in pc operation.
