How often is it rebooting? And it's not saying or doing anything it just 
randomly reboots? That seems more like a hardware issue than something 
OS related since the OS isn't even on those disks. If it's just data 
disks you could unplug them to see if the machine still reboots. That 
would let you know for sure if they really are the problem or if it's 
something else. Are you sure the power surge didn't affect the power 
supply? Also did you do anything to the system after the power surge 
(like open it up for any reason where there may be a loose wire not 
plugged in all the way). The last thing I would mention is this could 
all be a coincidence and it might be related to heat, make sure all your 
fans are working and that there isn't any big dust buildup inside (gogo 
compressed air).
