I have some problem with the Toshiba Satellite L505D-GS6000. Actually my USB ports and sound are not working. I opened the device manager and there I found that the exclamation mark for the high definition audio controller and it is saying that device cannot start. I tried to solve this isue in mnay of the possible ways that I know for this but nothing helps me. I will be really thankful if somebody can post some helpful suggestion for this. Please reply as early as possible. I am waiting for the replies.
