After a fierce battle with dell placing a new motherboard and frying one of my new memory since he forgot to detact the battery before opening my dell inspiron 700m. I was able to get the computer up and running again but the only problem now is I dont have sound. I have went to dell to download the Sigmatel C-Major audio drivers but still no use. I have restore the computer to the original out of the box and unistall the driver, then plug and play but still it is unable to start up with a sigmatel code 10.

The computer beeps so I know there is sound through the audio speaker but I dont see a speaker icon on the task bar anymore and when i go to volume control its states I have no mixer audio. Any help would be appreiciated
