I had took my computer up to the repair shop to see why it wouldn't post, and I was told that it would not post because the cpu was now down entirely, so they pushed it down more and it posted. However, a few hours later they called me and told me that my PSU was a bad PSU and that the likely cause was that since the CPU was not down all the way, the power fed to it went back to the power supply and short circuited it. Am I getting fed bs or is this a legitimate cause of PSU damage?
