Thank you for your answer. I guess you are talking about the following link http://www.jmicron.com/Driver.htm
which I of course tried as I said in my first post ("I tried to install the latest jmicron driver"). In fact I tried the latest and the specific version 1.17.39 I've found here http://www.x-drivers.com/catalog/drivers/sata_controllers/companies/jmicron/models/jmb360/8835.html
None of these solutions worked.
I may have not understood your answer, can you please be more precise when you say "use asus link".
Again, thanks for your time.
