This article was previously published under Q138741 SYMPTOMS
When you are running any of the listed Windows versions, your computer may
occasionally stop responding (hang). This problem is known to occur on
computers with the following chipsets:
OPTI-495SLC
CAUSE
The Turbo Switch feature of your system ROM BIOS is enabled. This feature
causes the computer to monitor keyboard input for a particular series of
keystrokes. When this series of keystrokes is detected, the computer is
placed in Turbo mode.
Windows also queries the keyboard periodically. When the computer and
Windows attempt to query the keyboard at the same time, your computer
may hang.
RESOLUTION
Disable the Turbo Switch feature of your system ROM BIOS. For information
about how to do so, contact your computer manufacturer.
