If you are working with a program that suddenly freezes all operations, 

chances are the program has stopped responding. You can exit the failed 

program without shutting down the operating system or closing other 

programs.
To close a program that has stopped responding:
1. Press Ctrl, Alt, and Del simultaneously (once), then click Start Task 

Manager. The Windows

®

 Task Manager window appears.

2. Click the Applications tab. If a program has stopped responding, the 

words "not responding" appear beside its name in the list.

3. Select the program you want to close, then click End Task. Closing the 

failed program should allow you to continue working. If it does not, 

continue with the next step.

4. Close the remaining programs one by one by selecting the program 

name, then End Task. Closing all programs should allow you to 

continue working. If it does not, power off your computer and then 

restart it.

The problems may be caused by your software or 

disk. If you cannot load a software package, the 

media may be damaged or the program might be 

corrupted - in these instances try loading another 

copy of the software if possible.
If an error message appears while you are using a 

software package you should refer to the 

documentation supplied with it as this will usually 

include a problem solving section or a summary of 

error messages.
Next, you should check any error messages 

against the operating system documentation.

If you cannot find a software problem, you should 

then check the setup and configuration of your 

hardware. First run through the items in the 

preliminary checklist as described previously then, 

if you still cannot correct the problem, try to identify 

the source - the next section provides checklists 

for individual components and peripherals.
