Here begins my tale of self-built pc woe. Awhile back I started having signs of PSU failure in that the PC would shut down without warning. I bought a new, identical power supply but the problem went away until Monday, when the PC shut down and then, when I tried to restart it one last time to save something before the replacement operation, the PC failed to do more than power on and then, before anything could happen, power back off again. Oops. Clearly I waited too long to do the changeover.
But I planned ahead! So I went and changed out the PSUs, but then the PC wouldn’t boot at all. No power, no lights, nothing. Utterly dead and unresponsive. Ok, maybe I jarred something loose. I went and tried to reseat everything, and in the process, because I am a hasty, dull-fingered idiot, broke some of the critical pins on the mobo for the various power connectors. Ugh. So now I need a new motherboard, and since the chip’s pretty old, I went ahead and got a newer one to go along with it.
All of which leads up to my question: can I install the new chip/mobo combination and simply hook everything back up the way it was before? My google-fu gives me varied answers, and I trust the people here way more than whatever old threads I find on reddit or tom’s hardware.
