Go to the download center and try the SATA Status Utility. It will tell you if you have a problematic board. Also make sure you have installed the Renesas SATA 3.0 driver.Still having problems see if you can update your Bios to Ver 2040. It is well tested by myself and many other members here and very stable. If the problem still persists you may have a bad drive (swap it out) or a bad Windows install. If you put a disk in the drive and it suddenly reappears and your using Windows 7 Control Panel>files and folders>view> uncheck "hide empty drives in computer".
Also make sure you have installed the Renesas SATA 3.0 driver.
Did you mean the Renesas USB 3.0 Driver? The DP67BG board does not have any separate SATA 3.0 drivers.
Yes I did...sorry for the typo.
Thanks guys for your help. Ran the app and installed the drivers with no success. I dont use the CD rom often but I did find when I moved my sata connector to another slot seemed to be ok, have not used it long enuf to see if it's going to disappear. As for the headphones, I'll keep using the cheaper headphone.
Thanks again for your help, God bless.
