help needed,sound card drivers..

ok,i really need some help as it's driving me nuts!
i have an advent 9212 notebook and i had a trojan horse which messed it up to the point i had to reinstall an operating system.it came with vista but i never had any back up discs as i bought it pre owned so i had to use a cracked copy of windows xp just to get me on the net to sort it out.
everything works fine but i am not getting any sound from it,there is no speaker picture on the screen and its saying no audio device can be found.i tied installing realtek audio drivers but they are not working and all the links i click are just downloads for driver scanners which then tell me i need to pay 24.99 to get the drivers.i am not very good when it comes to laptop problems so if someone could help me through layman's terms that would be great,i need this laptop for music and each day i cant use it its costing me money..please please please can someone help

 

thanks mate,that helped loads just having issues with sounds,in sund and audio devices there is no option to select anything..saying there is no audio device..what do i have to get one?

 

oh and also i now cant download anything :/

 

this is my problem,i have very limited knowledge of anything like this,hence joining the site.my downloads are working now (had to free up disc space using the disc cleaner)

the audio drivers are now installed but getting a message when i try to use windows media player that says it cannot play because there is a problem with my sound device,there may not be a sound device installed (but isnt that what the audio drivers were for from the site you showed me).
in device manager under sounds and settings i have the following things,all working properly.,not sure if a sound device is in it or not:
Audio Codecs
Legacy Audio Drivers
Legacy Video Capture Devices
Media Control Devices
Video Codecs


now,im pretty sure realtek should be in there?!.
i downloaded the rar file,extracted files and pressed set up and it ran through it all..am i right in thinking i have to put them on to disc and install that way?.

 

ok bud,thanks for your help it's really appreciated will try now and see how far i get.just hoping that the trojan i had last week hasn't somehow killed off my sound card (if possible).

 

If were talking leftover drivers and the like. Why not use Driver Sweeper?

Install but run in Safe Mode.

Running the tweaker now.sorry if my questions are basic,we weren't shown how to use computers much at school because they weren't that widely used,the internet wasn't around then in the form we have it now.
