Hi!
A few days ago I bought a new rig and after I've installed the OS (Windows 7 Ultimate x64), programs and other stuff I started to download my games from Steam. After a while I checked how it was going and I saw that the downloaded was stopped and when I was trying to figure why I saw that the drive disappeared. I checked the Device Manager and Computer---Manage and Storage just to see if I encountered some warning or something but nothing. I rebooted the computer and the drive appeared again.
I've changed the power and data cable but it happened again randomly. At first it was connected to the Intel controller and then I've tried with the AS Media controller. But no luck.
I even update the BIOS but no luck either.
This is my HW
Intel i7 4790K
ASUS Maximus VII Formula
2x250Gb Samsung 850 EVO @ Raid 0
ASUS Strix 970 no sé
Corsair RM850
2x16Gb Sniper G Skill 1600
1Tb WD Black Caviar
DVD-WR LG SATA
Zalman Z9
Searching in Google I've found that there are some other case with the same motherboard and with other ASUS ROG motherboards. But I didn't find any solution for this.
Don't know if it would be best trying to change the motherboard for some other model or what.
Other guys with the same issue:
