I can assist with your dead MOBO. What do you need help with specifically?
I chose to give my girlfriend an old PC, with its components (GPU and MOBO+CPU) safely stored in separate anti-static bags. To check everything, I built an open workbench. After cleaning the motherboard and connecting all parts, I powered it up using a screwdriver on the power switch pins. Something sparked near the top of the MOBO, so I turned off the PSU and removed it from the wall. A strong burning odor emerged, prompting me to dust the area again. This time a small flame appeared and gradually died. Upon closer inspection, I noticed damage close to the PSU port on the PCU header. It seems a short circuit occurred there. Photos and videos are attached. My questions: - Is the MOBO confirmed dead? - Could this short have affected the CPU, cooler, or PSU? I only detected the burnt smell around that spot and saw the damage clearly. - What might have caused this? I suspect a dust particle or debris inside the header could have triggered the issue. Even though the MOBO+CPU combo hasn’t been used since September 2022 and was kept in an anti-static bag, it’s possible a faulty pin was involved. This setup hasn’t been used since late 2022, but proper storage should have protected it.
Unless you possess the ability to swap those parts or take it to a qualified repair service, it’s likely faulty. It could mean the power outlet shorted something nearby, a cleaning created a connection, or there’s another unknown issue.
