Hey, I have a G5 / no iSight iMac. There is rumor that a power surge occured. When the machine is powered on, there are a few seconds of static, sounds a bit like pink noise, coming out of the internal speakers. After that, it will boot properly, and there's an occasional static sound. If there is no RAM in the machine, it obviously won't boot, but there is no static at all. Just that "tone" signaling the absence of RAM. Any ideas? Thanks.
