Problem with my sound card

Hello
I have recently formatted my pc, but the sound card (a Gembird SC-5.1-1) doesn't work. Since I don't have the original installation cd, I've downloaded the right drivers, installed them and rebooted... but the audio still doesn't work.
Maybe I did something wrong (I'm not properly a wizard with computers), but any help will be appreciated.
Thank you.

Hello,

Try to install this audio driver:

I installed it but still no sound
I've also tried to download the driver (FM801) from many sources, and tried to unplug/plug the sound card with no results at all

Hello,

Open device manger, select Sound, video and game controllers >> right click >> uninstall the audio driver and try installing the driver provided from the above link again.
