Time. Is the computer running slow?

Do you sometimes think that the computer is running slow?

Is it your CMOS clock or is it Windows ?

Well here is how to check it against Windows.

Go to :- Start > Run In the box, type without the quotes “ Cmd “

When the DOS window opens type after the Chevron > “Time “ Do not include the quotes.

Then Enter

Compare the time shown with the time in the system tray.

If they're different, the CMOS battery may need replacing.

However, if the CMOS time is correct and only Windows is losing time, you'll notice that the time is "fixed" by restarting the computer.
