No audio devices installed

[xxHayZEExx]

Hello guys, this is a problem I've been dealing with for quite some time, though I never really tried to solve it until a while ago. The main problem is this: (I wanted to post a pic of the icon but I couldnt due to lack of posts, its the speaker icon with the white cross on the red background)

icon showing up, when I right click it and go to 'volume mixer' it tells me there are 'no audio devices installed'. I've tried multiple things to solve the problem, I downloaded the latest drivers and installed them (didnt work), I 'removed' my (onboard) sound card with device manager and plugged in an usb sound card to see if that would solve the problem (didnt work). I went to device manager, 'removed' the onboard sound card then had device manager look for uninstalled hardware, it reinstalled the onboard sound card but didnt change the 'no audio devices installed' thing. Is there something left I can try to do? I'd appreciate any bit of help I can get!

PS: Im using a Windows Vista, if there are any specs you need to know about, just ask. Btw, when I look in device manager or control panel --> Sound, there is never a problem stated. I dont use speakers and usually have headphones plugged in. Also, when I start a game like Skyrim, it quits and tells me Skyrim needs a sound card in order to run, even though there's definately one onboard (not working though).
