What keyboard do u use? If Microsoft, there is a software in micorsoft.com
downloads where you can change the key setting.

also try to remove the keyboard files start>run>sysdm.cpl

Locate yourself to the keybord and remove it, your system will automatacilly
install the a new version after startup

accidental fix

I experiencing this too and accidentally fixed it.

my left ctrl mutes the sound and at the same time having a slow system due to high hardware interrupts.

After finding a fix for hardware interrupts I notice that it also fixed the issue in left ctrl muting the sound, heres how.

Check the problem by examining the controller’s Primary and Secondary IDE settings: Device Manager -> IDE ATA/ATAPI controllers -> Primary or Secondary IDE Channel -> Properties -> Advanced Settings. Look at the Current Transfer Mode field. If it’s “PIO” then it’s a FUBAR PITA and you’ll need to uninstall the driver, reboot and let XP do its magic reinstall.
