>>>>Yersinia is correct about your PRAM battery being suspect. If you don't have a suitable multimeter or battery tester, one way to find out if the battery is any good is to remove it entirely, and try starting up without it. You system should boot, but you will receive an error message re time and date being wrong/needing to be set. Use the Apple Menu/Control Panel/Time and Date control panel to set the correct time zone, time and date. All will be well until you shutdown. At the next cold boot, you will get the Time and Date error again unless you install a new PRAM battery.<<<<
The problem is the machine wasn`t booting at all! The machine boot stops after a couple seconds and then shuts down. I can give it a try, of course. As someone mentioned, I`ll try to clean the PSU with compressed air before. As far as I could tell, it had lots of dust inside. >>>>If you have the wrong RAM DIMM modules, you will hear the sound of breaking glass at strat-up instead of the normal start-up chord.<<<< The first time it booted after replacing the RAM hardware test was passed succefully, but got the bomb dialog when OS 9 loaded telling there was an app problem and the computer needed a safe restart from the keyboard. at that time I only an USB keyboard connected to the USB/FireWire PCI card which, of course, wasn`t working. It took me a week to try again with an ADB keyboard and them all of this happened.... Thanks for your suggestions!
