iMac shutting off and rebooting after a few seconds, looping
Texto:
My son's iMac, model listed on the side, appears to no longer be functional since last night. This morning, we noticed that it kept rebooting over and over, only getting to the chime and the loading bar every 3-4 boots. Every other time it just shuts off and starts over after you can hear it spin up briefly.
I've tried resetting PRAM and NVRAM already, tried internet recovery, internet diagnostics, various other startup commands... to no avail. Even in Target mode it shuts off and starts the reboot loop over.
Before I take it apart or get used replacement parts to try and fix it (leaning towards PSU, pretty sure any potential software causes are ruled out)... I wanted to see if anyone on here has any tips or pointers as far as what the cause might be, which part might be causing it, or if it's even worth fixing for such a relatively old iMac. I was hoping it would last a bit longer, heh.
Thanks!
