While it's possible, I guess, that corrupted data from a bad stick of memory could be written to a HD, thus corrupting the file system thereon....

Testing with a voltmeter is insufficient - that doesn't measure the power availble under load. Replace it with a new one. If the machine doesn't bong after doing so, then disconnect things - simplify the system. Remove all extra cards, all memory, disconnect the HD(s). With the memory missing, you should at least get multiple beeps, the indication from the self-test that it can't find the memory. If that doesn't work, try reseating the processor. If that doesn't work, the problem could be the PS. - Dan. -- - Psychoceramic Emeritus; South Jersey, USA, Earth. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed Low End Mac's G3-5 List, a group for those using G3, G4, and G5 desktop Macs - with a particular focus on Power Macs.
