I have just inherited a second hand Imac. I spent all weekend moving my itunes library from old PC and had no problems with machine. However, since Sunday, the machine itself seems to power off completely for no reason. I have noticed that on more than one occasion the power off has coincided with Safari being clicked/launched.
Once off the machine will not power on again for a period of time - no particular length in this case. I have tried various resets - unplug and hold power for 5 secs, switching cables with another mac, moving to another power socket. At one stage on Sunday, the fan came on constantly after a reset and had to be reset again.
Once on , the machine will run again for a certain length of time. I left it on sleep overnight last and it woke up ok this morning on pressing space bar but has crashed at least 3 different times already since then. Last crash was approx 15 mins ago and it still will not power on. Any help??
