I am using an ASUS CG5270 with Windows Vista. I bought it from a Best Buy a few years back and haven't changed any of the parts in it, so as far as I can tell these specs match what I have: http://www.cnet.com/products/asus-essentio-cg5270-bp003/specs/ .
About a week and a half ago I started experiencing primary disc failures on start up. After restarting it several times, I was finally able to access my desktop and back everything up to an external HDD. After that I switched which slot in the motherboard my HDD was plugged into and my computer hasn't given me a message about primary disc failure since then. I have a new problem now though. Whenever I start up the computer the Realtek High Definition Audio driver doesn't start up properly and my computer is completely silent. I have found though that if I turn on my computer, let it boot up completely, and then restart it the Realtek driver will load properly and my sound will work fine. I tried deleting and reinstalling the driver, but this didn't change anything. Is there a way that I can get my sound to work every time I start up my computer instead of every other time?
