Sound card stops computer from shutting down

Hey, I’ve recently installed a sound card in my girlfriends computer (soundcard from ebay) and the computer now wont shut down. I’m guessing this is a hardware fault, but figured I’d check here first. What action should I take if it is a hardware fault?

Thanks

First, Try it in all other slots, Then try another sound card , Or try that sound card in another computer..

…add check for driver updates for your new sound card to that too

[COLOR=“DarkGreen”]Ya, its better to check the sound card on a separate slot and on another machine.

How did you shutdown the machine, using power button or follows the Log Off option to end the session?

Listen to Ghost and make sure that you try different slots and try it on a different computer
