    While exploring BIOS I found "System Thermal" setting somewhere under APM and it was Disabled on my system. I wonder if it has something to do with the thermometer icon mentioned above. Is System Thermal Enabled on your G4?
    OK, well that's a start to fixing your problem. I think you problem is that your power supply is not adequate for the G4 since you said you are bench testing it. I had similar issues when I was bench testing mine. I had mine hooked to one of those battery jumpers. It worked fine for a couple hours, but when the battery ran down the G4 acted very erratic. It rebooted, crashed and other sorts of weird things and also depended what I had plugged into the USB ports.

    I have been reading about the bios settings and, yes, you can set the system thermal to lower your CPU rate when the CPU reaches a certain temperature. The CPU probably does this on its own without that setting enabled, but if you wanted to set it to a lower level you could. This would help for people that think their system is crashing due to temperature of the CPU. I am trying to make a digitalmod to display the temp, fan speed, and CPU rate for the G4 so we can monitor this. I think Speedfan will do it also out of SD.

    Can someone with a G4 out of the dash and turned on try to slap it on the side and see if it locks up or reboots? I am still trying to isolate my shock problem and this info would help me.

    Must say this made me chuckle the first time I read it, mine is all safe and sound inside my dash. But the thought of giving me $2k G4 a whack did make me laugh. I'm sure it wouldn't hurt it, but can't help here. Sorry.

    On a side note, within 30 minutes of opening my G4 package I was already installing mine and I haven't had any hardware related problem (the AM issue is apparently a SD update, should be fixed or I'll just go back to the last patch). Hope you two get it all figured out.

    Yes, definitely, and I appreciate your info about BIOS.

    No, I am not bench testing it any more, it's been sitting in my car now for two months now.

    Thanks for the info on system thermal settings. Will investigate further.

    Just an update: my G4 was recognized as defective by the local dealer and replaced with a new one.

    Where is the video located? I would love to see this. I man handle my G4 (mine was free) and I have no issues with shock.

    Also look into doing a thorough hard drive scan. I can't recall a program name off hand but the tools on ultimate boot CD work great.
