PC won't boot
Check the instructions for clarification. If possible, purchase a UPS. Contemporary systems are usually resilient to brief power interruptions, though frequent outages may indicate underlying concerns. Your PSU performed normally afterward, so it seems stable. You mentioned using a cleaning solution—what did you apply?
Removing the CMOS battery will reset the BIOS settings, so the system should start in its factory default state. The short video suggests you can’t even reach the BIOS, which is concerning since that’s where I’d first check for problems. It appears the PC is looping through the boot process but getting stuck at the video screen, which I’m not familiar with. You might want to try connecting the monitor via HDMI to access the BIOS manually. If you can remove the GPU and attempt to boot, that could help. Living in Southern China, I’ve experienced power issues occasionally, though modern hardware is much more reliable. You haven’t had any major problems like yours. The GPU seems to be the likely culprit—consider replacing it and asking someone with a working card for testing.
Make sure to obtain a reliable UPS before starting any work. Choose one that allows sufficient time to safely power down your equipment and delivers a stable signal during operation. A model similar to the one referenced here would be suitable. Although South Africa has different requirements, the concept remains the same. https://www.newegg.com/cyberpower-cp1500...6842102134
