High Definition Audio controller driver refuses to install

hello all

my computer has stopped playing any form of sound from it. Right now in the taskbar, theres a speaker icon with an x through it that says "No Audio Output Device Is Installed". Ive checked device managed and everything is working perfectly except for the 2nd High Definition Audio Controller listed. Theres a yellow exclaimation mark triangle through it that says code 10 (device cannot start), and then i investigated further and it said problems with PnP. Ive tried to reinstall it many times, restarted my laptop over 5 times and virus scanned my laptop over 10 times now. Im running windows 7 64bit.
