Okay, here is my dilemma. I have a Blue & White G3 Rev. 1 mainboard. It had an SCSI card and an older video card (not in the video slot, though). It also has a SCSI Yamaha 4x4x16x CD burner. When I boot up from Mac OS X 10.2, it shows an Apple character for a few minutes with the spinning circle under it. Then it slows a circle with slash through it where the Apple logo was, and the circle keeps spinning. What could be wrong? I tried resetting the NVRAM; however that did not help. Any help would be appreciated. Thank you.
