urgent help needed

My desktop has been having boot up symptoms where pc would power up and immediately shuts down then automatically power up again. Sometime it will turn on and off few times before booting up normally. Recently computer wont even boot up anymore, i would get no display and no HDD activity. The only thing is on is the cpu,case and gpu fans. I thought i had a bad psu so i went and ordered another one, computer still sometimes turns on and off but its alot less then before but it still will not boot up. Do i have a dead mobo?

What version of the BIOS are you running?

 

Have you experienced any system instability prior to this during gaming or when you are drawing a lot of power from the PSU?

only sign i had was last year the start up on and off would happen once or twice a month it became more frequent this year. Now it wont even boot up juts fans running and nothing else. I have tried using different psu, ram, reseating parts, clearing cmos nothing works. I think its the mobo. This was a fancy mobo almost $400 back in 2015 and yet it failed me with 6 years.

Sorry to hear that - yeah, not entirely sure what else it could be.
