[SOLVED] Computer does not turn on (Dead MOBO)

[BobMcSmith]

Hello!
Simple as the title: The motherboard worked fine for around a month, and then one day it wouldn't turn on-fans spin up and then crash, starts again and then crashes. Repeats like this infinitely. Nothing displays on the monitor, and no time to get into BIOS. However I have managed to get it to work by swapping the motherboard for an older one of the same socket. Is it possible the CMOS battery is dead? Can I swap the battery from the old one? I've looked for damaged capacitors and the like on the board and nothing stands out.

i5-7600k
ASUS H170 PRO GAMING (old, functioning board)
ASUS PRIME Z270 - A (dead board)
GTX 1060 6GB
16GB DDR4

You can try to use other CMOS battery, if you still have the same problem, I think the Z270 may have problem, because you need more tests.

Replaced the CMOS Battery, and everything worked fine!
