You may be holding the keys down too long while you’re
typing.
Keep the keyboard clean. Dust and dirt under the keys could
cause them to stick.
Configure the keyboard to wait longer before the auto repeat
feature starts. To adjust this feature, Go to [Start > Settings >
Control Panel], and double-click the Keyboard icon.
A dialogue box shows up with the adjustable settings for the
keyboard.

Try to reboot the system.
If the message “CMOS Checksum Failure” appears during the
booting procedure even after rebooting, it may indicate failure
of the CMOS battery. If so, you need to replace the battery.
