Performance Problems

For best performance, your computer should have at least 128 MB of memory (RAM).
If the computer pauses or runs sluggishly
This may be normal Windows behavior. Background processing can affect response
time.
Certain background operations (such as a virus-scanning program) can affect
performance.
Press CTRL+ALT+DEL and use Task Manager to see if an application is not
responding.
Restart the computer: click Start, Turn Off Computer, Restart.
Some file browsers respond slowly while processing graphics or waiting for broken
network connections to time out.
If the computer's hard disk drive frequently runs (as indicated by the hard drive light
on the front of the computer) while the computer appears to be paused or running
slowly, Windows is likely spending excess time writing to its swap file on the
computer's hard disk. If this occurs frequently, consider installing additional memory.
Check the amount of available free disk space. Delete temporary and unneeded files.
If the computer stops responding
Press CTRL+ALT+DEL and use Task Manager to end the application that is not
responding.
Press the power button for at least 4 seconds to turn off and reset the computer. Then
press the power button again to turn the computer back on.
If nothing happens, insert the tip of a ballpoint pen into the reset button on the bottom
of the computer. Then press the power button to turn the computer back on.
