Hi guys, I'm posting because I have a strange problem with my iMac intel (which i bought two years ago now). The problem is this: - He reboots alone without any message or asking me to do it, it's just like a power switch off but it's not! because when it happens I didn't noticed any variation on the light or other running devices using the same plug... He can do it between 1 and 10 times in one day, or once a week or nothing for a month. Lately he reboots while he is rebooting... and that what worry me. I thought it could be a virus or even a corrupted application so I installed ClamXav but he didn't find a thing, then I tried MacScan but nothing wrong fund too. Anyone can tell me what that can be? Thanks for reading.
