Hi, I want to ask you for help 
I have a computer with a gigabyte ga-p31-es3g motherboard and it worked until yesterday without a problem. 
Yesterday when I start the computer, load it up and BIOS beep and no detect my drives: sata hdd and pata dvd. 
Then I reboot and everything was fine, and found two devices. 
I update the BIOS but still the same problem the first time not detect devices after I restart my computer everything is fine. 
Thank you in advance
