iMac g3 beeps 3 times
I have an iMac g3 that two days ago was running OS x 10.2.8, I installed OS 9.1 and restarted it. When it turned on it beeped three times, and nothing on the screen. I managed to get it to turn on and load the OS, but it still beeps. I really need this running due to it is my school computer at home. It has come up with a warning. A few times in OS 9.1 saying the hard drive has an error, but the computer worked fine. Please help!
iMac, Mac OS X (10.2.x)
