iMac shutting down before progress bar finishes
Randomly invested in a $20 not powering on iMac A1125 3.06GHz Core 2 Duo with I'm guessing 4GB RAM (2 x 2G and Apple states capable of 8GB max though one seller I found has a 16GB max option), NVIDIA ? and 1TB HD with one other I can’t read option noted (see image in FB link below). Seems like a neat upgrade from the free eMac’s with Leopard installed.
Read online what I could find, unplugged and held down the power button for ~1.5 minutes, plugged back into the wall 120VAC outlet and then pressed the Power Button to observe the Apple Icon with a progress bar that slowed down progressively to about 3/4’s the way stuck and then the iMac powered off after ~5-10mins. That’s all the computer would perform.
Read this link, https://discussions.apple.com/thread/847..., where nothing appeared to do anything other than the #3 ( restarted the computer when I’d hold down the keys and #8 automatically performed, what holding down the <Option> or <Alt> booted to the two drives Untitled and Recover 10.11.5 and selecting Recover 10.11.5, to show the Apple Icon and the progress bar stuck halfway before powering off. I also, had to repeat the above unplug from wall outlet power button procedure after the recovery boot attempts.
Read also that upgrades can cause issues and since appears El Capitan was installed based on the Recovery drive title and Snow Leopard is more likely the circa OS X version… I’m guessing there is something wrong with the 10.11.5 install. Therefore, I’ve decided to download the 10.6 ISO and create a USB boot drive with to first Diagnose using Disk Utility as noted here: https://business.tutsplus.com/tutorials/...
I’m thinking I can also create a USB boot drive using Time Machine on one of the eMac’s… though don’t have a 10.6 DVD and thinking is a good idea to at least have the ISO available.
Any other observation of the causation of the symptoms I’m having?
Does anyone know if 16GB can be installed in the model I have?
Regarding the Memory question per Apple specs:
Wondering if I need to replace the battery or like my first thought there might be something up with the PSU also like noted here:
I don't notice any SMPS ticking sounds or smell anything burned. Guessing if I decide to install an SSD to replace the magnetic HD I'll perform a very thorough cleaning, replace the thermal paste on the CPU & GPU and possibly upgrade or hack in another fan with a 3D printed vent to flow more air through since does feel a little warm over the PSU.
