I have a lot of PC133 RAM laying around from various PCs I've parted out. I thought I would use it to bring my Power Mac G4 Sawtooth up to 1GB from 640MB. So, I put the RAM in, hooked it back up and turned it on...but it made a horrible staticy sound instead of the startup chime and it never displayed anything on the monitor. So I reseated all the RAM sticks and the start up chime was normal, but it still didn't display anything on the monitor. So I put the original RAM sticks back in, and it again chimes like normal, but it still isn't displaying anything on the monitor. I hope I didn't kill it Please help!
