First off, first time poster - long time mac lover and used to be mac owner - went windoz, now trying to get back in the mac world. with that said, I purchased a PowerMac G4 Dual Processor 1 Gz QuickSilver 2002 (Model M8493) off ebay a couple of days ago - haven't received it yet but am trying to prepare for getting it up and running. It needs a hard drive and memory before I can even start that but first I need to figure out if there is a hope of using the present motherboard/processor and hoped that someone might be able to advise me. Evidently it was purchased as a working machine but when he added his memory and hard drive it quit on him - read below: PowerMac G4 Dual Processor QuickSilver 2002 I Gz (Model M8493)—For REPAIR or PARTS. This computer will not boot up. The startup chime did ring for a while without booting, but now the power comes on but no chime. The power supply tests Ok and the graphics card works in my other PowerMac. I am not sure what else to check. However, it comes with some great parts: • Superdrive (DVD-R/CD burner combo) • SCSI Card • Zip Drive • GEF4MX graphics Card. • Does NOT include Hard drive or Memory. It's been ages since I've worked on Mac's but he didn't do any real troubleshooting - suggestions? Ideas? Where to start finding out if its savable or just need to buy a new inner works for it? I know I'm asking for the sun and the moon people without much to go on but the first thing I thought of was that old trick of zapping the pram 3 times and then going into the bios (is that right?) and ....okay there my memory goes faulty....might something as simple as that fix it or does it sound like a major deal? Once I get my hands on it, more info could be added but I'm very excited about this and can't wait to get off this PC and back to the MAC!!!
