memory test locks up computer
So if I'm running the TechTools Pro memory test, and that consistently locks up the computer, does that mean the RAM is bad or something else is wrong in the system. Normally, I would just expect TechTool to come back and say the memory test failed, but I've seen this one iMac lockup everytime at about 10% progress bar everytime. So I replaced the RAM with new stuff, but it still locks up (arrrgh!!!). Is it possible something else is messed up on the motherboard or chipset?

But yeah, if the memory management unit is flaky on the logic board, that could cause problems even if the RAM is fine. If you haven't swapped out that factory installed ram yet, do that... otherwise make sure there are no peripherals attached to the iMac and try booting with no extensions on next time you run the tests.
If it still locks up, I'd say you've got a logic board problem of some sort.
So I guess then it would be up to you whether you think it would be worth it to fix. You won't get a new iMac for $800, but you can get pretty close.
