A Buffer Overrun is actually a common attack on a computer that is designed by computer hackers. It is one of the most common forms of security risk, and it happens when unchecked external data is treated as trustworthy. These types of attacks are quite common with C and C++ coding that have poor coding practices in place.
Symptoms of Buffer Overrun
When a Buffer Overrun occurs, one of two things will happen. It could be that your application will abort with a core dump, access violation, or segmentation fault error message. That is unfortunately a best case scenario. In the worst case scenario a hacker can exploit weak files and add their own malicious code which can be hard to catch, until you realize your online security has been compromised.
Causes of Buffer Overrun
Malware can be the cause of Buffer Overrun, especially if the hackers have had their way with your computer’s files already. However, another cause may be a registry that has become corrupt due to being unorganized and cluttered. Whatever the cause may be, it is important to root out a Buffer Overrun as soon as it is discovered.
Fixing a Buffer Overrun
Whenever a Buffer Overrun problem occurs the first thing that you should do when attempting to fix it is run a complete anti-malware scan on your computer.
- Locate the anti-malware software icon on your desktop or computer tray.
- Double-click the icon.
- Run a full system anti-malware scan.
- Allow scan to compete.
- Any malware that is found should be put in quarantine or deleted.
Restart your computer after these actions to ensure all changes take effect.
Trayapp is a specific type of software that is automatically installed with most HP printer products. The software is needed so that the HP device in question can scan properly as well as print photos. This type of software is also known as HP Photosmart Digital Imaging software. Occasionally, a Trayapp error can and will occur.
Trayapp Error Symptoms
When a Trayapp error occurs you will not be able to use your HP printer effectively. Furthermore, a manual forced shutdown will be required each time you log off of your computer. This is not a problem that will go away on its own and will likely only get worse if left alone.
Cause of a Trayapp Error
Though a Trayapp error can have several causes there are a couple of more common causes that typically are the culprits. One would be that the MSI file used for the application is missing and/or corrupt. It could also be that a registry entry on the PC itself is corrupt which in turn will cause the error to occur.
Fixing a Trayapp Error
The easiest way to go about fixing a Trayapp error is by using the HP device’s installation disk.
- Start your computer.
- As Windows is starting up insert the HP product disk.
- Allow the Windows Installer to run.
- If a missing file is found by the installer it is likely to be replaced.
- Once the Windows Installer has finished restart your computer.
- See if the Trayapp error persists.
A Syntax Error is one that occurs in the syntax sequence of a particular program that is intended to be written in a certain computer language. This can happen in a number of programs and when it does there is typically an error message that is associated with it.
Symptoms of a Syntax Error
Whenever a Syntax Error occurs the end result is not being able to access the particular program that you are trying to access. The telltale sign of course would be the pop-up style error message that alerts the user to the fact that such an error is occurring.
Cause of a Syntax Error
A Syntax Error can be caused by a variety of factors. Most commonly, Syntax Errors are caused by misspellings or bad punctuation. This is commonplace when a program tries to translate itself from one platform to another. The problem can be further intensified if the PC in question has a cluttered registry that has therefore become corrupt.
Fixing a Syntax Error
Syntax Errors can often be debugged and fixed automatically, but in some cases manual manipulation may be needed.
- Open the computer’s code and compile program.
- Locate the manual debugging tool by looking on the toolbar.
- Look under the Tool tab and search for Debug or Debug compiler.
- Click result found.
- Review the code for errors.
- Fix all errors you find.
- Save all changes then run the compiler.
- Restart your computer when the process is complete.
Check to see if the Syntax Error persists.

The 502 Bad Gateway error is one that is not all that common, but can come up in a variety of ways. Sometimes it will come up reading differently as 502 – Service Temporarily Overloaded or even as HTTP Error 502 – Bad Gateway. However it happens to come up is a nuisance when it does.
502 Bad Gateway Symptoms
When a 502 Bad Gateway error happens the user is alerted with a pop-up style error message. There usually isn’t any precursor to the problem as the error can occur with some websites and not others. Once it happens though, the end result is not being able to access a website or a certain page on a website.
502 Bad Gateway Causes
When the 502 Bad Gateway error shows up it means that one server has received an invalid response from another. This is known as an HTTP status code error and usually means it is not a problem with the PC itself, but rather a server that is trying to be accessed. However, in some instance s it can be files in the PC’s registry that are corrupted which will prompt the error to frequently occur.
502 Bad Gateway Solutions
Since a 502 Bad Gateway error is usually directly related to a server problem there are three things to try when resolving the situation.
- Retry the action. Use the refresh button on your tool bar to attempt to reload the page.
- Come back again later. Sometimes a 502 Bad Gateway error is only a temporary problem of the website you may be trying to access.
Contact the webmaster of the website you are attempting to access by using the e-mail email@example.com and alert them of the 502 Bad Gateway error. This won’t always be a valid e-mail address, but it is more times than not.
