Hi everyone! I'm dealing with an MSI B450M MORTAR (latest BIOS) setup paired with a 2700x, 16GB CORSAIR VENG PRO RGB, GTX 650TI (still in the 3000 series range), and CM MWE 750. This rig has been running smoothly for about a year until recently. After a power outage, the system stopped responding properly. When I pressed the power button, the motherboard lights came on but then shut off instantly—completely bricked. After clearing the CMOS, it would turn back on briefly before failing again when I tried to restart. Once I replaced the CMOS battery, things stabilized. I tested turning it on and off, disconnected the PSU to simulate a power cut, and it worked fine afterward. Now it keeps refusing to boot. What could be causing this sudden problem? It seems normal when it's running but not when it powers off.
