Hello, I've scoured the web looking for answers, and can't find any, so maybe someone here would be kind enough to help. I'm working on an iMac 350 blueberry for my sister and I'm having all sorts of trouble. She bought it last week, it started up (8.6 os) no problem. Powered up and down a few times, then all of a sudden, it won't boot. I'm currently getting blinking folder/happymac/question mark when trying to start up. Here's the big problem - the keyboard and mouse do not work now. I've tried three different mice and three keyboards and no dice with any of them. I have the 8.6 CD from her previous imac (bondi), and I can hear it spinning, but there is no way to start up from cd. I've also tried 2 other hard drives with the same results. Tried resetting CUDA on logic board, taking out battery, no change. Bought new battery- no change. I would love to at least get the keyboard working to see if I can even startup from cd, anyone have any clues on how to get it working? The strange thing is that the keyboard has a power on button, and it works to start the thing up, but dies when it tries to boot. Sometimes I just get a grey screen with the pointer icon, and I can move the pointer with the mouse for a second or two, then no response. I appreciate any help or suggestions on locating the issues! Thank you!
