PC can't get to BIOS

[Jordan_129]

My PC will not power on, I cannot get to bios screen. The desktop is receiving power as the pump LEDs and on-board button lights up. I have systemically removed all peripherals, GPU, RAM. I have gotten it to boot twice, once after a CMOS reset. I originally thought the problem was the battery so I have replaced it with a new one. It booted the other time after removing GPU, but it feels like a fluke due to it not booting on afterwards even with the hardware removed. Do you guys have any tips on what could be the problem?

you gotta hit the Del fast before it goes post BIOS

First two things to do.
1) Check PSU voltages - Recommend one of the Cheap PSU testers See Link. Alternative is to use a multimeter (Voltmeter)

2) Reseat all connectors for Power to MB, Reseat RAM

you have got a devil´s canyon CPU which could be not compatible to your current BIOS version of your motherboard.

Update it using the USB BIOS flashback function of your motherboard:
