No sound

Hello,

so my computer is really slow and a scan shows that I have like 19 outdated drivers. . . what's the easiest way to update my drivers and how do I find out if my system came with a sound card or not? I've had it since 2005, it's running xp, and most of my devices are less than a year old. I have automatic updates turned on, so what else can I do to prevent this from happening again once I get the devices updated??

Thanks!
