I was having the weirdest problems with my 7600 (UMAX 233/320/2x2G/VooDoo3 2000/PC Comp 100 mHz/8.6 & 9.1), where it was having all sorts of random and increasingly more serious freezes, lockups, HD problems, and so on. By the end, with me taking out added ram, removing the newer HD, pulling all the PCI boards, etc., it continued the exact same problems. I tried TechTool Pro (no problems), DiskWarrior (3 x "No problems," 2 x all sorts of small, odd ones), and was running Norton when it locked down in the middle of a check. I tried starting with a system CD disk only (both 8.5 and 9.1!), and even did a clean reinstall of 8.5 to no avail - same problems and more frequent.
Finally it refused to start up at all, hitting the point where extensions start loading and bombing out with an "Unimplemented traps" message, and then suggesting I restart with the extensions off - problem is, it would do the same thing *then*! I to it to the local shop (AIS/Sandy Springs), and all they told me was wrong with it was a "bad logic board," quoting me $540 for parts/labor/tax to fix it. My questions here are: - Has anyone ever seen something like this? - Does "bad logic board" really sound like a definitive diagnosis, or is it something more along the lines of "It's sick"? - I bought a new 7500 logic board off eBay - assuming it is good (it was cheap so no serious loss if it isn't) - is it indeed identical to the 7600 logic board? (all my sources say it is, but one never knows...) - Will an afternoon spent plugging in this new board, accompanied of course by appropriate chants, meditations, offerings and incense, drive out the demons that infest it?
