Hi, I recently got a B&W tower PowerMac G3 (don't know exactly which model) without DVD reader and HDD. I powered it and saw a grey screen with a folder and a question mark followed by the finder logo. Probably couldn't find OS X (duh). At least it booted. I powered it off, got a OS X Tiger install CD, got an IDE DVD reader I had lying around, a 30GB HDD and plugged them in. Went to boot again but nothing happened. Just the chime and then nothing. No beeps, no video, no grey screen. Tried turning it off, disconnecting power and turning it on to drain it completely. Is there any kind of troubleshooting flowchart or steps to resolve issues? I don't have a Mac keyboard with me. I'm using a regular USB mouse and keyboard with Windows keys. Also, neither the mouse or keyboard lights turn on after the chime. Are the USB dead? or it gets stuck before powering them on? Thanks!
