  1. Hello everyone! I recently got an iMac G3 cheaply from a thrift store missing the hard drive and ram, but it powered on and gave the beep signal for no ram, so I bought it. I got a stick of ram from a friend, installed a hard drive, and it even powered on to the blinking question mark. However, after returning to the computer after burning an install disc for the OS, it no longer would turn on. I will attach a video of what it does. https://streamable.com/pnoq2 In case this does not load, the speakers click a few times, and the CRT makes noise that sounds like static that persists for several seconds after I let go of the button. I do not get power LED, bong, or HDD spinup. Things I have tried: -resetting PMU (with the motherboard button) -leaving iMac unplugged for 2 days and trying power on -leaving iMac plugged in for 2 days and trying power on -disconnecting hdd and CD drive to reduce psu load None of this has fixed it. I have tried googling but have gotten everything from people saying it is simply a bad p-ram battery to capacitors to PAV failure. I really want to get this machine working (my first apple computer, although I am far more experienced with PCs) and these problems are out of my depth so I need some help to diagnose the issue. Computer info: -blueberry 1999 slot loading -350mhz, no FireWire -ram: pc133 (compatible to PC 100) 256mb -hdd: 120gb Western digital 7200rpm Due to coronavirus, I don't have most of my tools (normally I have access to an oscilloscope) and haven't gotten access to a new pram battery to change as the shop that sells them is closed. What can I do to get this computer running? Thank you in advance for your help! I tried to cover all info but will give more if needed.
