Why, after falling, is this iMac cycling on and off?
I am considering buying a defective iMac, and this is what the seller can tell me about it:
"The computer will boot for a minute and then shut down and restart itself and continue this process and the restarts get faster till it wont do anything. It may only run for 3 min on first power up before the restarts happen.
This began happening after it took a fall from a desk and after replacing the (shattered) glass pane on the front."
Any guesses on what would be wrong with the thing? My first guess would be the logic board, but then again, I would also question the power supply. I just don't wanna buy the thing and be stuck with a bricked computer, as the parts are pricey. And yes, I know what I'm getting myself into... I've bought and sold defective computers quite a bit.
Is this a good question?
