Recently built new PC and I've been having some very peculiar issues after a bios update. After the update, PC immediately powers on as soon as it is attached to power (gpu, mobo, fans), but no signal to the monitor. Cannot get to bios, no image at all. Tested multiple monitors to multiple sources and all have video, but nothing from the gpu. mobo does not have on board VGA to hook up to as far as I can tell. Removed and re-seated all power, RAM and peripherals (everything that plugs in). Using single ram and swapping different ram. Tried switching to secondary bios, resetting bios/cmos switches (unplugged and powered off for multiple seconds each). I feel like I've pretty well done everything minus removing the cmos battery, as I dont see it anywhere (can someone point me to where it is). My body is ready.
After everything, the same error. PC power on as soon as powered and no image. Mobo error code is reading "00", but i believe its an error error code trying to tell me cpu temps. I dont know, I'm dumb.
Mobo: z390 msi godlike
Psu: seasonic focus 850
RAM: Tried both tridentz rgb and vengeance pro rgb (did not mix)
Would really appreciate any help or assistance. It would mean a lot.
