Because several readers write about their computer responding slowly, I am posting a summary record of basic steps you can take to resolve the DNS zone has no start of authority (SOA) record.issue, and briefly discussing the three most common causes : malware, uncontrolled applications, and insufficient maintenance.
Maybe the greatest contributor to a poorly performing computer is malware.
Stage 1. Revise the definitions of your anti-virus and operate a complete scan of your hard drive in Safe Mode. Resolve any unfixable problems. Note that some viruses require extra measures until they may be removed; normally a websearch will find specific directions or a particular removal tool. If you cannot find a answer, use the BC forums to request assistance.
2. You’ve recently downloaded an application, and if the sluggishness is unexpected, the problem may dwell there. Test this by completely eliminating it. A user will generally perform a web search about the application before downloading it because in most instances, any potential difficulty with malware or poor performance will have surfaced.
Step three. Adware and Spyware can drastically impact your computer’s performance, and these are around the World wide web.
Revise the explanations of your anti spyware programs and check your hard drives in Safe Mode. Seasoned customers will often run two or three of the programs, because each company has its own standards for what constitutes spyware and will only search against their own set. (A set of really good, free anti-spyware programs is supplied by BC). Again, resolve any open issues before proceeding to the next step.
For further reading about Malicious software and some malware removal applications, use BC’s Tutorial section; most of the programs have quite good Help documents that clarify how they work as well as the distinctive features of each.
Step 4. Evaluation applications that self-start on startup. You pc can be a battleground for your interest. Many programs, for instance, install a fast-launch feature which allows them to be opened promptly; other programs may contain an automatic update feature that requires them to be running in the background. Each of these slows down your launch Windows and each needs a little bit of resources while your computer is running.
The simplest approach to examine and than to manage startups would be to work with one of many small utilities available (see the BC list of free apps). Remember that BC maintains a quite complete Startup Database that includes info about whether the item is needed, optional, or not needed, if you are uncertain about what can be safely deleted.
At-the same time, remember that all those icons on your own Background also take a small number of boot time to set themselves.
Absence of Maintenance
Stage 5. Clean up your hard drive (preparation for Stage 7). Delete unused applications and exchange old files into a CD. Unplayed games, tons of family images, zipped files that you have previously opened, applications you haven’t found in two years, software for that old printer you put away last year—these are a few types of files you can delete. Then use Window’s Disk Cleanup to remove temporary internet files, temporary PC health files, etc.
(Note for sophisticated users: some specialists would comprise the added maintenance stage of cleaning the Windows registry, and you will find plenty of apps to assist do that. For the most part, so this measure is not included, you may do serious damage by making registry changes, registry maintenance won’t make a major difference, and unless you are quite comfortable with Windows, and carefully make backups of the registry
Action 6. Run scandisk / checkdisk in Safe Mode. Have it repair DNS zone has no start of authority (SOA) record..
Step 7. Defragment your computer. Windows will set new files in any available open space; defragging will set associated segments of files closer together therefore your read arm has less going around the hard drive to do, saving wear and tear while boosting up plans.
Hopefully, since you have have concluded, you will see a noticeable improvement in pc functionality.
