System fails to start following a power loss.
System fails to start following a power loss.
Yesterday I was using my PC and suddenly the power went out. Being tired, I just went to sleep. When I turned it on today, only half of the screen appeared, with black borders around the middle. I restarted the computer to check if that would help, but now it won’t start at all. The green "boot" light is on and shows the Asus Q-Code 02, which means "AP initialization before microcode loading." I’m really stuck and have tried everything possible, thank you in advance for your help.

Have you experimented with repositioning RAM and similar components? Occasionally systems hover just outside stability before a power cut disrupts everything. My thought is the power supply unit or mainboard might be faulty, which explains why the CPU isn't even starting its microcode—something fails during the POST (Power-On Self-Test). In today's terms, a failure to boot means something didn't pass the test. Booting actually happens before the UEFI starts, and previously it was handled by BIOS; now firmware manages hardware tasks and the interface. Try testing with a different PSU or motherboard if you can.
