well, it did it again. honestly, i can say that i have tried EVERYTHING. there is no hope, i believe. as i mentioned earlier, the crash takes place in the following OSes:
10.0
10.0.3
10.0.4
AND
10.1
10.1.2
10.1.4
10.1.5
i've tested my ram THOROUGHLY trying various combinations of apple-only ram and third party as well. since the machine worked perfectly well at my job prior to bringing it home, i assume that either something environmental at my house is affecting it, or perhaps it was damaged in transit. since i have ruled out heat and vibration, as well as dirty power and network traffic, i can only assume that the machine was somehow damaged while bringing it home.
a firned suggested that due to a hairline crack in the motherboard, things like what i am experienceing may happen. especially with the expansion and contracting of the silicon while powered on from heat.
i have a few more little experiemtns to try, but i don't know if they'll help:
1.) swap processors with another machine. (from a G3 400 to my G3 450...)
2.) bring another machine home. this will entirely rule out any environmental problems.
yeah. thanks for all the help.
