Question My motherboard may have died

I was watching videos when my computer turned off, I tried to turn it on but nothing so I disassembled it and reassembled it, it gave some signs of life for a few seconds in the bios and then it turned off. I disassembled the whole board and poured isopropyl alcohol on it and rubbed it without too much force with an antistatic brush and left the motherboard to rest for a day.

I tested the motherboard again today but without any success, the motherboard's LEDs light up but not even the cooler turns on, I tested it with another processor that I have (Ryzen 5 2600), and other memories (Asgard) and it didn't turn on at all, I even connected no components to it to see if its Qled would indicate that it doesn't have a processor but nothing.

Could it be that rewriting the bios via the rear button will bring it back? I already had a similar incident at the beginning of the year, which was due to too much humidity and it came back after a few days, lasting until this Monday

My Specs:

Ryzen 9 5950x
Asus ROG Strix B550-F
Crucial Ballistix 4x16 3200 mhz
Asus TUF RTX 3070
XPG Core Reactor 850W
