Hi Gadjo, An extension conflict is one, however setting the upgrade to a higher than allowable cpu multiplier/bus speed ratio is also another consideration. At least you get your startup chime and video; I don't get the chime/video when my settings are way too high. Set the upgrade to a lower cpu/bus speed ratio and retry. Also trash System Preferences - it may have been corrupted. Charlie -- PCI-PowerMacs is sponsored by <http://lowendmac.com/> and...
