I'm having boot issues on my MSI H61M-P31/W8 motherboard

Hello to the entire MSI Community.
I come to you because I currently have some boot problems due to my old MSI motherboard (H61M-P31 / W8).
I'll tell you, on December 4, I was using my PC normally, when in the middle of 11:00 AM-12: 00 PM in Colombia (yes, I live here) in my sector there was a fairly small power outage (approx. 2 sec) and it turns out that when I tried to start it, the PC turns on and maintains a sustained boot (that is, it stays on) but does not give video; the hard drive was active (if you touched it you felt the typical vibration that tells you it is running), the heat sink was working and so was the power supply; that was the only drawback. The only way I was able to get it to boot normally and give video was by removing the battery from the BIOS and disconnecting the PC from the power completely (that is, unplugging the power source and turning off the power switch) and wait +2 minutes to connect everything again and turn on the PC.
Asking about this on a Discord server where they offer somewhat basic or intermediate support on these issues, they told me that the power outage may have caused these things on the board:
- The power supply may have broken (which is illogical, because the power supply was changed 2 months ago, but it is also true that it can happen, even if the power supply has been changed)
- The BIOS could have been short-circuited (the BIOS could have been damaged internally, and now every time the PC starts the BIOS does not start normally if not with the methods described above)
My question is: you, community, with the knowledge you may have about this, tell me, what could it have been? The truth is that having to do this every time I have to use the PC is quite uncomfortable.
Thank you and I hope your answers.
Juan
PS: All the specs of my PC are these:
CPU: Intel Core i3-3240 CPU @ 3.40 GHz
RAM: 4 GB DDR3 (Dual-Channel)
Power supply: Unitec ATX750W
Motherboard: MSI H61M-P31 / W8
Hard Drive: Toshiba DT01ACA050 500GB
And the PC is almost 9 years old.

Age of your PSU doesn't matter, brand and model does and it isn't very good. It probably is missing some protection circuitry reputable PSU brands(i.e. Be Quiet!, Antec or even kind of mediocre in comparison to others [still better than no-name] FSP) include in their products, I'm not even mentioning these 750W. It very well might be faulty at this point. As for motherboard it might have suffered some damage from the PSU, but for now check voltage on BIOS battery (this round one on MB), should be ~3V.

Hello jakub-p2, first of all thanks for answering me.
As for what you tell me about the BIOS battery voltage, this was the only thing I could find in the Aptio Setup Utility (BIOS) of my motherboard, I don't know if it works, but it was the only thing I found there. And physically checking the BIOS battery, yes; is 3V.

And with what you comment on the damage of the power supply, I agree with your suspicion; I'll start looking for someone who can replace her.
Thanks for everything.
Juan

If voltages on these images are anything close to reality your PSU is out of ATX spec and shouldn't be used - 3.3V is too low, and CPU temperature is INSANELY high for BIOS operations. Remember, a PC should also be serviced - replace thermal paste and clean it. From what I see, if You can, please borrow a PSU from your friend and check if it works, as I think that the PSU doesn't send PWR OK (or PWR GOOD) signal form the PSU controller chip to the MB which results in voltages stabilizing, but PC not starting.
