    Pc shows no signs of life out of nowhere

    Hey people! So ive had my pc for about 6 months now and a few days ago when i tried to turn it on it showed no signs of life. No lights, no fan spin, no beeps, nothing (it worked perfectly previously). My first suspicion was a bad psu but i tested it using a jumper bridge and it worked fine (psu fan started spinning so i considered that working). My logical conclusion is that the motherboard went bad because after i plugged everything back i didnt even get a spin from the psu. It’s probably good to mention that i only had an exhaust fan that came with the case so could it be that the mobo was overheating without me knowing and then just died out of nowhere? I am still super puzzled as to why this happened but if you guys have any ideas or suggestions on what to try that would be great!

      I did the psu test once, when I had a pc that would not power on.. Installed new psu and everything was fine.

        Yeah, checked pretty much everything and even tried to bridge the power pins on the mobo with a screwdriver but to no avail

          Check the mobo for budged caps or ones that might be leaking.
