Have You Gotten Stop Errors Messages?
If you have recently, or in the past, received stop errors messages, then you are aware of what has been lovingly dubbed the “Blue Screen of Death.”
Blue screens errors are typically caused by software errors in the drivers. However, there are other causes. Sometimes the device drivers are sloppily written. More recently, dynamic-link library, or DLL, drives become incompatible with the system or have other bugs.
On other occasions, stop errors are caused by overheating, a faulty ram, or a failing hard drive. In most cases, stop errors messages are a simple fix.
What Will Stop Errors Do to My Computer?
The error screen has been a problem for PCs since the early days of their inception. Unfortunately, these errors are hard to fix by a layperson with no technical skills.
What happens with your computer for the blue error screen to appear is that your driver runs across a damaging error from which it cannot repair itself. As your PC works to protect your saved data and files, the system restarts without any warning.
In the newer Windows family, most of these errors are from illegal activity on your PC. When a program attempts to access an invalid memory location, your PC will be met by the stop errors.
On many occasions, you will find a box that has a message which may read similar to “Windows Operating System is not responding,” followed by a pair of options. You could either choose to wait for the system to respond, or you may be forced to stop running the system, or close the program.
Typically, if these errors get to the blue screen of death, you have little hope for system recovery unless you manually reboot. It may also require you to startup in “Safe Mode”.

Registry Cleaners Save PCs
All of that work is far too daunting for some to know where to begin, so there were registry cleaners to do all the legwork for you.
Registry cleaners are the best defenses and preventive measures against any actions that may incite stop errors. Besides quality virus protection software, you need a registry cleaner to keep you PC running at peak performance with regularly scheduled disk defragments and scans that help you understand what the actual problem is.
There are many cleaners available on the Web for download; but not all cleaners are created equal. Some cleaners are programmed to find an extensive amount of “errors,” so that they incur more paid downloads.
Other cleaners are full of malware, Trojans, and viruses. Some cleaners fix errors automatically, without asking you first. This can be dangerous if, for example, the registry cleaner is one that discovers massive amounts of errors.
Most of the errors found by these cleaners are not errors at all, and changing the registry could do even more damage to your PC.
Choosing a trusted registry cleaner is worth doing the research for. When looking for a cleaner to download, you want to be sure to read consumer reviews and the manufacturer descriptions.
If a cleaner is backed by a trusted name, follow that trail even deeper. Look to read if you will have the option of selecting which files to repair or not. Always be certain that not one instance of a system crash or drive failure has occurred because of the cleaner.
As unfortunate as stop errors are, there are programs to help repair these little bugs. With the assistance of a registry cleaner, in addition to regular maintenance, your errors will be reduced if not eradicated altogether. And you will be glad to see your system run much faster and more smoothly.
