about a week ago the sound on my laptop stopped working. i got the red x along with the no audio device installed message. i looked online for solutions and tried a bunch of stuff as it seemed to be a pretty common issue that could be easily remedied. nothing i have tried has worked. i tried downloading a new audio driver, tried updating the driver but whenever i do i get a message that says the driver loaded incorrectly code 10 error wont let it start. i've tried the realtek driver and i get that message, the only time it doesn't happen is when i install the conextant audio driver but that causes my computer to automatically shut down and restart, after a few times o restarting i get a blue screen with a fatal error message(very scary) but then my computer fixes the problem by doing a system recovery.a couple times the sound has returned but soon disappears again and i am back to square one. as you can probably tell i know very little about computers. i have an hp pavilion dv2000 and am using vista. any help/advice would be greatly appreciated. thanks in advance.
