My roommates 2000 has the same problem. He has an 8UP! board with 4megs, and an xt bridgeboard. His made a buzzing noise for a while, but I could almost swear that it actually was his fan. Now when he turns it on, the power light comes on for about a second, and then shuts off. I took out the two boards, but to no avail. So, if anyone has any ideas, there are at least two people interested in them. Any help would be appreciated. It may very well be the fan. If the fan doesn't start (and thus draw current from the +12V supply), the supply goes overvoltage and shuts itself down. Or so I was told when a similar problem happened to me. This *seems* to be confirmed by the behavior of my A2000. My fan will not reliably start itself. If I just turn the computer on, I get the one second burst of power, followed by nothing. If I turn the computer on while spinning the fan (so that it will start--it runs fine after that), everything works fine. Try replacing your fan & seeing what happens. I haven't replaced mine, yet. My wife thinks that I'm nuts for living with a computer that I have to turn on by sticking a toothpick in the back while flipping the switch. -- Andrew Heybey, ath@ptt.lcs.mit.edu, uunet!ptt.lcs.mit.edu!ath
