Centris 650 turns on by itself...

[Sandisk78]

Hi, people ! Centris 650 turns off by itself when I just plug in power cord - now tried to put working cmos battery - the problem stayed... And besides that the machine is working - installed 86 mbs of ram and 2gb HDD, os 7.5 - runs not only games, but photoshop 3.0 and tonns of other software - but that's annoying that all the times I have to unplug power cord)

On the rear of the 650 is a rotating (start) button with a slot in it, turn it 90 degrees.
