Microsoft and other Technicians can use the information that Dr. Watson obtains to diagnose and troubleshoot a program error. When an error is detected, Dr. Watson creates a text file (Drwtsn32.log) that can be delivered to support personnel by the method they prefer. You can also create a crash dump file, which is a binary file that a programmer can load into a debugger.

There are many ways to solve the problem depending on the cause of the errors; and one of the most simple and effective methods is to reboot your computer. This method only works if the error is related to interaction of software with another programme causing programme crash or system crash.

See if your problem is resolved?

A crash is when something experiences a fault and has no choice but to stop or exit. In computer system, an application crash means that the programme has encountered an error and has to be terminated. This can be caused by something as simple as file conflicts, or trying to access a section in memory that has either become damaged or that belongs to another process.

When a programme or software is crashing, we need to check the possible causes and try relative solutions. After all, we need to make the programme or application work. Here below are some troubleshooting method that we can try when a programme suddenly stops or crashes.

1. uninstall and reinstall the application.

In many cases, if a programme fails to work, the reason may be some corrupted components in the programme during installation. Thus the programme does not function correctly and populate the error. By reinstallation, we can reconstruct the software components and replace those corrupted with correct ones. This method sounds very simple but may possibly be able to solve the issue in a minute.

2. temporarily turn off your protective software

When a programme fails to work, it may be blocked by other software, for example, an antivirus programme. When you install a programme, the antivirus software will always ask if you want to block it. If you do not pay attention to the notice, you may accidentally block the application. So, when you run the application and find it cannot start, make sure to check the black list in the antivirus. It is suggested that you add the application to the white list of your protective software.

3. turn off or uninstall programme that may cause conflicts

For some functional software, such as antivirus, anti-malware and optimizing tools, they do not tend to be friendly with their kind. They may conflict, or even fight with each other. Why? Because these tools are fixing tools and they need to take control of the whole system, including other software. When both of them try to take control of the computer, they will begin to fight. So, you may uninstall one and just keep the other one.

4. fix the memory damage to allow system read the programme information

As we mention above, application crash may be caused by damaged memory. To settle this issue, we will need to fix the damage in the memory. But you cannot do this by yourself; you will need to use a memory fixer. Download and install the memory fixer, it will quickly scan your memory ram and fix the damage for you. After the fix, you will not have application crash anymore.

After installing Windows Live Messenger, you may be getting error 800488eb when you try to log in the programme. Hense, you will not be able to use the programme.

Here below is the error message:

We can’t sign you in to Windows Live Messener. Please try again later.

Error code: 800488eb.

If you look into Microsoft website, you will find that there is no Microsoft released announcement about this error. The cause is unknown, neither the solution. And if you look on internet, you will also find there are many people suffer from this error, but there is no absolute solution so far. In this article, we will introduce some troubleshooting methods for this error:

First, uninstall and reinstall windows live messenger.

In many cases, if a programme fails to work, the reason may be some corrupted components in the programme during installation. Thus the programme does not function correctly and populate the error. By reinstallation, we can reconstruct the software components and replace those corrupted with correct ones. This method sounds very simple but may possibly be able to solve the issue in a minute.

Second, check your mail account and passwords.

This sounds silly but sometimes it really happens. When you suddenly fail to log on MSN, and you are sure you have made no change to the computer recently, then you may have to check your account and passwords. It may just be a typing mistake.

Third, check your internet connection.

Windows Live Messenger depends on internet to work properly. If you have no internet connection, or the network is having some problem, you cannot log in on the messenger. To settle this problem, you will need to ensure the network is connected, and then, open internet explorer, follow below instuctions to fix the network setting: Tools > Internet Options > Connections > LAN Settings and uncheck all the boxes.

Fourth, check your computer date and time, make sure they are set correctly.

If computer has incorrect date and time, there will be trouble for the internet to communicate with your system. Certificate errors and server errors will occur and it will be difficult for you to log on any websites or servers. So it is important that you make sure the validity of the date and time.

Additional advice: Virus and malware can corrupt the registry and cause numerous problems in your computer, including the messenger error. Registry fixer can detect and clean messenger error for you. Any delay will lead to unimaginable more serious issues. Remember, 90% of the computer problems are caused by registry issues. So it is always recommended that you install a registry fixer to consistantly protect your system.

Copy and paste commands are two of the most common operations we make on computer. It is not exaggerate to say that we use these two commands every day. There are too many cases that we will need to copy and paste something. For example, when we want to store some information from webpage, the most usual way we would use is highlighting the information and pressing Ctrl+C at the same time, which is what we call Copy. And then we will open a word document or text file, right click and paste the information onto the file.

Copy and Paste commands are very important for the efficiency of works. Especially when it comes to pictures editing, using copy and paste will save your time to store the pictures on computer first and then import the pictures from the folder to any program.

What if suddenly you can’t copy and paste anything on your computer? The most frustrated thing is, you will not be able to store anything from webpage. This can cause great trouble if you have any urgent paper work to be done. The issue will also low down the efficiency of your other works which need copy and paste to improve the speed.

How about the cause of such issue? The reason is not clear unless we do a troubleshoot. There are some possible reasons: IE error, third party programme influence, registry errors, etc.

1st: IE errors

According to Microsoft, one of the possible causes is Internet Explorer error. Because My Computer and Windows Explorer use Internet Explorer, if Internet Explorer is damaged, some of the functionality of these tools may be lost.

To resolve this problem, use the following steps.

• Click Start, point to Settings, and then click Control Panel.
• Double-click Add/Remove Programs.
• In the Add/Remove Programs dialog box, click Microsoft Internet Explorer, and then click Change/Remove.
• In the Internet Explorer and Internet Tools dialog box, click Repair Internet Explorer, and then click OK.

2nd: Third party programme influence

Some third party programmes, for example, Advanced System Care, have a function of disabling clipboard, which means that, the information and data you copy will not be stored in the clipboard. Thus, you will not be able to paste because there is no data being kept.

The solution for this case is easy. Just open the programme, find the option of disabling clipboard, uncheck it and apply the change. You will find that your problem is solved so quickly.

3rd, registry errors.

If above two solutions are not able to fix the error, the cause may be deeper, perhaps one or multiple registry errors. To solve the issue, I will suggest you download and install an advanced registry cleaner to resolve the copy and paste error. Any delay will lead to unimaginable more serious issues. Remember, 90% of the computer problems are caused by registry issues. So it is always recommended that you install a advanced registry tool to consistantly protect your system.
