So my $10 gamble on a 2004 dual 2.0GHz G5 failed. The system worked the day I picked it up and then refused to start the following day (yesterday). Troubleshooting the issue it appears the motherboard has succumbed to failing solder joints around the memory slots. I was able to confirm this by taking a screw driver and applying pressure to the motherboard near the CPUs. When I did so the system began to boot until I removed the pressure at which time it froze. I'd like to see about using a heat gun to attempt to reflow the solder on the motherboard. In order to do this I need to remove the CPUs which seems fairly straight forward in the various disassembly videos. Except for one small, but seemingly very important step: The removal of the cover over the CPUs. Apparently there is a pin which secures the cover in place. This pin seems to be exceedingly difficult to remove as shown in the following video (around 13 minutes in): I could mangle this pin as the individual in the video ultimately ends up doing. However doing so seems excessive...it's a pin and I would imagine there has got to be an easy way to remove it. Anyone have experience with its removal? If so is there an easy way to remove it so I can reinstall it after I take it out? Or is this designed to be replaced each time this CPU cover is removed? EDIT: For anyone who may come across this post in the future the symptoms I experienced are well know. My research revealed many, many, many posts where people were experiencing the symptoms but there were few diagnostics as to the problem. So I thought I would add it here. Symptoms: Systems powers on, fans spin, power light flashes three times, no video, no chime. Eventually fans begin to spin faster. No motherboard diagnostics lights are illuminated. The overwhelming number of posts which asked about these symptoms were answered with "check your RAM". The advice is sound and is the first thing I would recommend. If after verifying your RAM you can try replacing the battery and resetting the PMU. If neither of those fixes the problem in all likelihood you've got a failing motherboard. You can try testing as I did by applying pressure to the motherboard right next to the processors. Do so in the area that looks like a square...most likely as close to the processors as reasonable. If you use a screw driver as I did ensure you place something soft down (I folded up a microfiber cloth into a small square). This will help to prevent physical damage (though it's not best practice due to static electricity but I figured what the hell...it's broken anyway). Don't press too hard....you don't want to crack the motherboard either. While holding pressure try powering on the system.
