No Restart in OSX


I finally got OSX to reboot from the disk and install everything(which took about 20 minutes) . I had to put my Newer Tech G3 300 card in and take out my Sonnet G4 450. Crazy! Now the only way to get back up and running is to hold down option key to boot OS 9. OSX will not restart, it turns the screen black and then shows no sign of life- no harddisk noise either. Any ideas?
I would use the startup disk app included with the OSX CD. Start up from the OSX CD, copy the app over to your OS9 partition and open it, then select OSX to boot up. From there once in OSX you can then select OS 9 thru the startup disk control panel in OSX
