I have a Z77X UD5 motherboard i've bought 2 years ago..
Last year my Corsair SSD died and frankly I blamed the cables and the SDD itself. The motherboard was fine. I switched it with Samsung Pro HDD and went on. Since last week PC was acting weird, it was taking too much time to boot up (let's say 1 minute with fast boot and everything).
Today my harddrives and ssd, everything died. PC itself is booting up but none of the harddrives is being recognized by stupid motherboard. I can't even access to BIOS menu because I/O and front USB panel is not working either.
Everything was fine in terms of maintenance last night, i had no notifications from Samsung Magician or the Windows itself.
I have no idea what's wrong...
It's not cables, i'm sure of it. Tried different and even original cables and no go.
It's not harddrives, i'm sure right now, since it's the second event with same mobo.
SATA ports ?
Faulty motherboard ? I can't send it to guarantee anymore since it's more than 2 years.
