I discovered my Kernel panic on startup was caused by bad ram, so I replaced the ram with new stuff but I must not have seated one correctly. Upon restart the 1.8 G5 bonged twice and the button on the front started blinking. I quickly shut down and reseated the ram, the G5 rebooted quickly with no kernel panic but the fan is now stuck on high speed which is not correct. How do I get it back to normal I've tried resetting the pram but it didn't work. Checked the forum but found nothing on this problem.
