some of my sound has gone

hi all,
last week my sound on the pc was working fine, this morning the sound only works if im watching a film, listening to music etc but wont work when I start Windows, (start up tune) or when I change pages it usually makes that clicking noise, but not anymore. ive checked my audio devices to make sure i hadnt accidently clicked 'mute'. I did notice in device manager that there is a yellow ! on my media/audio. when i right click onto it and go into properties and try and rollback the driver it says it cant rollback as no drivers are installed. I dont know what to do now, It advices me to download the drivers via the internet, but i dont know what or if there is a sound card or motherboard make. how can i get the sound on Win XP back, as i can listen to music and films, but there are no more warning alerts, start up/log off tune.

Ive tried to re-install the drivers but the pc cant find it, the sound device is "creative sound blaster PC1 {ES1371, ES1373, WDM}"
I did get a cd audio + video driver with the pc (a copy) but there are that many folders in there I dont know which one to go into and i dont want to be opening files i dont understand incase I mess my pc up more.

 

go to the "sound and audio devices properties" in contorol panel, then open Sounds tab and choose windows default scheme.

 

I've done this but it makes no difference.

 

it also states this in the hardware tab on video/audio devices....
Freecom DVD+/-RW4B
Hitachi DVD ROM GD 2500
Standard game port
Audio codecs
Legacy audio drivers
media control devices
legacy video capture devices
video codecs
creative sound blaster PC1 ES1371, ES1373, WDM (it did state this but now it isnt there)

 

Did you try system restore and set it back to a point when your sound card worked fine?

 

Hi

for some reason i cant restore my pc, ive tried various dates but with no success. I dont think my pc likes me. I cant use the win xp cd as i didnt get one with the pc and when i bought the pc all i did was plug my speakers into the back and it worked fine, but now,,,,,,,,,,as above.

 

It sounds like you'll have to go out and buy windows xp.
