[HELP! have I bricked my install?]

Update: It was an AHCI Setting in BIOS that was disabled

[HELP! have I bricked my install?]

I was updating my CPU's in my acer altos G540. Im running DSM 6.1. has been running fine for months if not years.

 

CPU's had issues so I rolled back to original CPU's but not I have the screen saying 'No Hard Drives found on DS3615xs"

 

HDD's are pick up in BIOS, everything seems to be the same. 

Is there anything I can do?
