Windows 7: New pc, No Sound?

I built a computer on pc specialist, it came with vista but i got someone to put windows 7 onto it.

I now have no sound, can anyone help me? i have no speakers in my monitor so i bought some logitech ones.



I have made sure they are plugged in the right slots and still nothing?

I have
Sound Card ONBOARD 8 CHANNEL (7.1) HIGH DEF AUDIO

Can anyone please help?!!!

The drivers are installed ?

Dont know much when it comes to this sort of stuff, can you lead me in the right direction for them please?

Most likely you need to go here for your audio driver.
Realtek

The link on that page isnt doing anything, just going back and forth. any help please ?

Give us more precision about your sound card onboard, for exemple I have : "realtek ALC 888"

I can find the drivers you want if I have enough informations.

all i know is

Sound Card ONBOARD 8 CHANNEL (7.1) HIGH DEF AUDIO

When i hover over my volume ( bottom right ) it says Digital Audio (S/PFIF):100%

Sorry, im so useless when it comes to this sort of stuff!

Don't worry.

Try this : Mes Drivers - détection en ligne automatique de la configuration matérielle et des drivers compatibles

Click on "lancer la detection", install what they ask, then click on "lancer la detection" again.
You will see the list of your hardware, with the drivers who correspond.
Find your soundcard in the list and install the drivers.

Sorry i cannot figure that out in the slightest, i intalled what u said and it comes up with a list of my downloads?

Anyone have anymore ideas please? im just sat waiting.. i have no idea what to do :\
