[QUOTE="pigoo3, post: 1528511, member: 56379"] The reason why I asked if this computer was working fine (while in your possession) is...it makes a BIG difference when trying to solve a problem...if the computer owner knows if the computer worked fine BEFORE a problem arose. In many cases (when folks buy a used computer very cheaply)...it's because the computer had a problem...and now the new owner is "rolling the dice" hoping that they can solve the problem...and end up with a perfectly working computer for very little money. Here's what I can suggest: - Boot the computer with the OS install disk you have (OS 10.4 I'm assuming). - Open Disk Utility and reformat the PB's HD - Then install OS 10.4. Obviously if this is what you did already...then I guess you could skip this step. Since the computer has NEVER worked while in your ownership...I'm going to suggest that maybe the ram in it is "bad/defective"...or it's the wrong ram for the computer. This is one reason why I asked about the ram initially. One thing you can do before purchasing new ram is...remove the ram...and reinstall it. This "reseating" may get things working. If this doesn't fix things...then try a PRAM and a PMU reset: [url=http://support.apple.com/kb/ht1379]About NVRAM and PRAM[/url] [url=http://support.apple.com/kb/ht1431]Resetting PowerBook and iBook Power Management Unit (PMU)[/url] If trying everything I mentioned above doesn't fix things...then I'm thinking that you need to purchase some ram (ram you know 100% works with this 12" PB). This is not a 100% guarantee...it's simply a troubleshooting step. It is always possible that something is wrong with the logic board on this computer...and no matter what we try will fix things. And if this is the case...then this computer is ready for the junk heap (or sold as a parts computer on e-Bay)...since a replacement logic board usually is not worth the cost versus the current market value of the computer. - Nick [/QUOTE]
