I bought it last year 2020, and up till 3rd August 2021 it was working properly. On 3rd August I tried booting it and did not boot. It looks like the cooling fan blows a little then stops I sent it to the repairer but he says he has to change the power supply unit and up to now he still hasn't got any?
I have the same problem with my HP 8200. I put the power supply from a hp 8000 computer and it booted up so i know it's not the power supply.I'm thinking problem may be in either ram, bios chip or possibly a short somewhere. Does your 6300 processor fan spin up and stop a few times and then stop like mine does?
