Greetings,
You don't state anything about your system specs - if unsure then I recommend you download this utility (Belarc Advisor) :
http://www.belarc.com
It will scan your pc and give you a full profile of all components and software installed - handy if you need help in future.
If you have them - try reinstalling the drivers for your graphics and sound cards (alternatively if your pc has onboard sound on the m/board - try reinstalling the relevant component from the motherboard cd.
If you can't find the cds or they are scratched / unusable - simply post details from Belarc here in another post. Someone can then try and find a suitable link for you to download them.
Good luck - post back how you get on.
PS - Hope your weather there in FL is better than here in London
