Java Crashes
Java crash – An error in executing programs
Java crash is a term used to define a run-time error that occurs whenever a user tries to open a web page that requires Java to execute. As a result, the web browser or mostly Explorer crashes. The only result or remedy for this error is to reinstall or reload Java but it does not proof a useful solution in some cases.
Java crash occurs at random times during the execution of the system’s programs and the work done up to that level is lost and cannot be retrieved. It happens eventually without the prior knowledge of the user. The Web applications such as JIRA and Confluence, etc. are running in a Java virtual machine (JVM) which is mainly responsible for managing the memory, CPU and the devices attached with the system, same as the operating system take care of applications like MS Office, web browsers etc. A JVM crash is visible by getting a characteristic ‘Windows Blue Screen of Death’ while using MS Office or a web browser and occurs when the JVM is running low of the free memory.
The Java crash is an error that occurs in JVM not in the software operating within the system. These crashes are sometimes the result of JDK bugs that can be fixed by installing new JDK version. When this crash happens, it is due to the execution of two threads that are calling VTK C++ calls. These two threads are:
· The main event thread
· The finalizer thread which performs the garbage collection.
For example, see the following call:
vtkPointData t = pointPolyData.GetPointData (); vtkDataArray u = t.GetNormals();
What happens is when the GetNormals function is being processed in the C++ side, then due to some system’s processing reasons, the garbage collector starts thinking that t can be de-allocated to empty the allocated memory locations. So, the finalizer thread deletes it from the main event thread which is actually expecting it to Exists. Therefore, Java crash appears and the program is stopped from running.
Sometimes, the reason for Java crashes is thought to be the use of weak global references (NewWeakGlobalRef and DeleteWeakGlobalRef) as the weak global references do not behave as a real reference. Therefore, the objects get collected in garbage during the thread call to native method. The use of non-weak global references (NewGlobalRef and DeleteGlobalRef) helps to avoid these Java crashes.

Yahoo Mail is the best known service of Yahoo because they provide a huge space in inbox and is very easy to use. Errors in yahoo mail are also a part of it. In this article I am going to explain what does the yahoo mail error 6 does.
Yahoo mail error code 6 is an error which does not allow you to receive or view your new emails that should be in your inbox. This error usually occurs due to the java applet which is pre installed in new browsers like Internet Explorer 7, Internet Explorer 8 beta, Firefox 3. This is because Yahoo mail server does not support java applet. This mail error 6 occurs due to software compatibility. This error has not been solved by Yahoo yet, which I think is really frustrating for people who use Yahoo mail and get these errors.
Yahoo mail error code 6 can be solved very easily. I would suggest you should use the older versions of Internet Explorer or Firefox, because with these versions, Yahoo Mail just works fine. And what else would anyone else want when they get no errors from their email client. Well, this was my personal suggestion. Apart from this if you really want to get rid of this yahoo mail error code 6. All you have to do is set your Internet setting according to make your email client work. Below are given some steps to resolve this issue, I hope this will help you out.
1: Go to Tools in your Internet browser window,

3: Then all you have to do is just scroll down and find if you have Microsoft Virtual Machine listed.
4: If you have the Microsoft Virtual Machine listed down, just clear the box against the 2 java’s listed.
5: Make sure JIT box is checked, click apply then ok.
And I am sure that this will resolve the issue and if it doesn’t, then I must say you must go for the old browser.

Fix corrupted JPG files
JPG files are image files in the computers.JPG stands for JOINT PHOTOGRAPHIC GROUP. These files are normally the image files which consume less space as compared to other formats such as BMP. This format for the image files are used all over the world. People prefer to keep jpg files instead of bmp. This image format is mostly used in every camera and other photographic devices. This is the best format for images, because it not only consumes lesser space but it also keeps the quality of the desired image up to the mark. This is the only reason why people use this format for images the most.
If a jpeg file is corrupted due to data loss or some hard disk failure. The biggest drawback I can tell of jpeg files is that these cannot be fixed, if corrupted. These files are really sensitive files. You should make the backup of these files so you may never regret that you have lost your images forever. Maybe there are some software’s which can recover your files for you, but as far as I know there isn’t any software that can completely recover the corrupted image files for you. The only solution for your corrupted jpg files is that you delete them from your computer.
And the second solution to this problem is that as soon as you get your jpg files in your computer; try to make a backup of those files on a CD/DVD, flash drive or some sort of floppy e.t.c. The corrupted jpg files are the ones which cannot be recovered through any method. Jpg files are the most commonly used format in the world, there should be some methods through which one can recover the corrupted files, but with complete sorrow, I have to tell you that there isn’t any method still through which you can recover your corrupted jpg files. All you can do is take precautions for the next time and do make the backup of the files and never get the same problem ever again in life.
This is all I could have explained you about the corrupted jpg files. Hope it helped you out.

Win32 Generic Host
In windows xp, a number of people have faced and they are still facing Win32 Generic Host error. The first reason is that your computer is filled with much kind of viruses that is infecting the computer and one virus is getting over another’s configurations that create even more complexities and as a result Win32 Generic Host error occurs.
So the first thing that you should do is to scan your computer thoroughly for viruses. If you are not able to run antivirus on your computer, then you should start it on safe mood and then try installing the antivirus. This would not be fair to rate just one antivirus good or bad. So when you are looking for virus search and destroy, search internet for antivirus ratings and chose the one with the best feedback and ratings because the tag of good antivirus and virus killers changes frequently. Internet is the biggest source of this kind of software. They might be like a package of a good working program and a spy thread in it, or it might be something like a total file that contains material to spy. If you have downloaded some software from an unsecured website and you think that this would not harm your computer, then you can continue executing it. If the file disappears after running, it is 90% a virus.
Viruses are not the only cause of win32 generic host troubles. A legal DLL file may also cause this. When that dll which has an association with svchost.exe is crashed and you have to restart the system, the win32 generic host errors will occur. In this way, you have to reinstall windows. This is not necessary that you format all of your hard disk and start a fresh copy of windows, but you can also overwrite the existing version of windows. This will replace the corrupted files and if that software does not runs again that caused this problem, the computer would be fine.
If you have just installed some update from windows’ server, this could also be the reason that the update does not match the system requirements or the software that is previously installed in your computer conflicted with that update. This most probably happens in windows xp service pack 2.
That last reason of win32 generic host error is that you have installed some old driver of the hardware issues by hp and those drivers are not computable with the new version of svchost.exe. So, search for the new drivers and the problem might get solved.

How to Reinstall Yahoo Messenger
If you have been having problems with your Yahoo! Messenger, such as freezing, slowness, and/or automatic shutdowns, it may be time to try reinstalling the software. This could fix any corrupt files that may be causing the errors you are experiencing. You should start by uninstalling the current version of the messenger from your computer. Be sure to make a backup of your message archive if you wish to save it, as it will be deleted once the program is removed.
To remove the old version of Yahoo! Messenger, be sure the application is not running prior to beginning the uninstall. Open ‘My Computer’ and select the ‘C’ drive. Click ‘Program Files,’ then ‘Yahoo!’ Click the Yahoo! Messenger folder once to highlight it, then press the ‘Delete’ key. Alternatively, you could right click the folder and select ‘Delete’ from the menu.
Note that the ‘C’ drive is the default location for the messenger. If you chose to place it somewhere else on your computer when you initially installed the program, you will need to find it, and delete it from there. Removal can also be done from the ‘Add/Remove Programs’ screen in your Control Panel, which is found in your Start menu.
Now that you have rid your computer of Yahoo! Messenger, you can proceed with reinstalling the software. Be sure no applications are running with the exception of one Internet Explorer (or your preferred Internet browser) window. Visit http://messenger.yahoo.com. Click the ‘Download Now’ button in the middle of the screen. Follow the prompts on the screen to reinstall the software. Select ‘Run’ when it gives you the option to Run or Save. You may want to uncheck the boxes that will make Yahoo! your default search engine or home page. Accept the Terms & Service of Yahoo! Messenger, and the installation should begin. Once complete, your new version of Yahoo! Messenger will be ready for use.
If you created a back-up of your message archive, you will need to locate it once the new messenger software has been installed. Copy the back-up folder, and paste it into the ‘Profiles’ folder in the new Yahoo! Messenger program. The default location for the software would be C:\Program Files\Yahoo!\Messenger\Profiles. This will allow you to access your archives from the Yahoo! Messenger software.
Sometimes, for unknown reasons, Yahoo! Messenger will begin to work unsatisfactorily. Reinstalling the program is often the cure for the errors caused by the program, so a quick update wouldnÕt hurt when you are experiencing problems.

Code 19 Errors
Consider that you are working along on your computer and suddenly you encounter a Code 19 error. Now what do you do?
First you should understand what a Code 19 error really is. A Microsoft XP resource kit will tell you that this code means that your Windows will not start the hardware device because you do not have the right configuration. It may also mean that the registry is either incomplete or that it is damaged. This is a condition that might happen after you install and then uninstall devices or software when you are troubleshooting your computer’s problems. You can try to take your computer back to the previous state before you started getting the Code 19 error. Often this will solve your problem.
Most of the time the Code 19 error will appear after you have attempted to install a scanner. There are things you can do to make an attempt to provide a solution to this problem. First you should click on Start. After that you should right click My Computer. Here you will find Properties. Under the Properties tab you should click the Hardware tab.
After clicking on the Hardware tab you will then click on the Device Manager button in the Device Manager section.
When you are in the Device Manager section you should then look for the Imaging Devices. You may either see a + or – beside this section. The + will expand the list and the – will minimize the list. By clicking the + you should find your scanner name. Here you will be able to view that the device is either working correctly or you will see an Error Code 19. If you see the error code you should then launch your trouble shooting wizard to find the source of the problem. You will probably need to uninstall and then attempt to reinstall again. You may end up doing this several times before you get it correct. After each time you reinstall you will need to restart your computer to apply the process to your computer’s systems. If you keep getting the Code 19 error you will need to reset your computer back to the previous system restore point.
Anytime you get an error message on your computer it can be frustrating. Often the reason we get those messages is because we fail to exercise patience. You should take the time to read and understand all of the instructions before you attempt to make changes to your computer settings and programs. One wrong click can bury you in a sea of error messages that you may never be able to dig your way out of.
If you find that you have installed computer components and you are not able to resolve your computer’s issues at home you may need to seek out the services of a computer technician. The frustration that comes along with error messages can cause you to do even more harm than you already have. A technician can explain to you what you need to do and perhaps you can write down the steps so that you will avoid a future problem.

Fix Virus Infected PC
A virus is a harmful program that can damage files, cause computer crashes, or have a number of other negative effects on your computer. While nobody wants to get a virus on their PC, in many cases it’s possible to remove the virus and repair your computer with very little difficulty. You should be able to remove spyware, viruses, and other damaging software before they can cause additional problems and optimize your PC in order to prevent future infections.
One of the first things that you can do in order to get rid of viruses and remove adware or other harmful software is to use a virus scanner to perform a deep scan on your PC. This scan will search for any virus that may be on your computer in order to isolate the virus files so that they can be deleted. Similar software can be used to remove spyware or other malware, an important step as many of these malware programs can lead to further virus infections or PC damage.
It may require more than one virus and malware scan in order to remove spyware and viruses from your computer, since some of the virus files may not be able to be isolated on the first scan. Should the scan still not be able to isolate and remove the virus file, you may need to take your PC in to a computer repair specialist so that they may use more powerful virus removal tools which will be able to scan the computer for the virus files before the Windows drivers and other files that the virus may be attached to are loaded.
Catching a virus early can not only prevent crashes and other problems but will also save you from the file damage that viruses can cause. You may have to replace a few infected files if they are corrupted or otherwise damaged by the virus infection, but that’s much better than potentially having to replace your operating system because of a virus infection that got out of control.

Cure PC Crashes
While there are a number of things that you can do in order to speed up boot time on your PC, an unexpected computer crash can make the time it took you to optimize your PC wasted. In order to prevent crashes from ruining your computing experience and possibly damaging your computer, it’s important that you know what some of the most common causes for these PC crashes are. Here are the most common causes for PC crashes as well as what you can do to help avoid them.
One of the most common causes for PC crashes is power-related problems; this can take the form of either power failure or a power surge. While there isn’t much that you can do in regards to controlling the flow of power into your house, using a surge protector power strip can help to keep your PC safe from damage caused by power surges. An external universal power supply can also be useful, since it will give you a few minutes of power even in the event of total power failure so that you can shut down Windows properly and avoid potential damage to files, hard drives, and Windows drivers.
Other common causes of PC crashes include spyware, adware, and software virus infestation. Any of these programs can make your computer unstable, even if you’ve previously taken the time to optimize your PC. Scanning programs exist to detect and delete virus files as well as to remove adware, but you need to remember that regular scans are required to remove spyware and other dangerous programs.
Yet another common cause of PC crashes is software malfunction. In most cases a problem with Windows drivers or other critical software is resolved simply by rebooting your computer. Should the problems continue, they are easily corrected by simply reinstalling the driver or software suite that contains the malfunctioning program.
One last common cause of PC crashes is simply having an overheating processor or motherboard. This can cause your computer to run slowly even as you try to speed up your PC, and will generally result in crashes that give no warnings. If you suspect that your computer is overheating, make sure that it has adequate ventilation and that the fans or cooling system are working correctly and are free of dust or dirt.
