My PC crashed yesterday (it's previously been rock solid since November when I last reformatted) and after a forced restart I couldn't get past the "Detecting SATA 2" during POST, where it froze.

After pulling one of the drives (Vertex RAID 0) I got the bios to boot all the way to the RAID part where it said that one of the drives had failed (probably because it was unplugged).

I reset the bios from RAID to ACHI, reformatted the remaining drive and performed a clean install which worked fine.

today it crashed again, I can't get past "Detecting SATA" in POST. I've tried different SATA ports and cables but to no avail. The chance of two SSDs going down is fairly remote I would have thought?

I'm wondering if this is a motherboard SATA issue?
