Heyyy

so went on vacation for 2 weeks. everything working fine before i go.
Came back and pc wont boot. usual trouble shooting later, it boots up after reseating ram.
i game heavily for a few hrs and switch off. next morning again it doesnt boot, reseat ram its good to go again.

When it doesnt boot, it shows a vga error :| aaaand weirdly enough i can hear the windows 11 startup music :|
so not exactly sure if boot error or some firmware bios issue :|||

Specs
Windows 11
Ryzen 5600x
gigabyte b450 pro wifi
gigabyte 5700xt
and corsair ram 2x8gb

any thoughts ? im guessing maybe it jumps to integrated graphics?
the mobo and cpu are a month old the rest of the system is older like 3-4 years atleast

You forgot to include the make and model of your PSU. Is that 3~4 years old as well? Also, have you tried working with a fresh CMOS battery? Might want to relocate to another wall outlet and see if the issue persists. Do you get a mild tingling sensation when you make contact with the metal part of your chassis, while your feet are touching a tiled(non-wooden, non-carpeted) floor?

What were they prior? As for the platform, did you reinstall the OS after the migration to the new motherboard?

What BIOS version are you currently on for your motherboard?

My bad the psu is a Seasonic m12ii 620. and yes it is been in use for a bit.

I was running an 1800x on an ASUS crosshair hero 6 x370. I dint reinstall the OS but I did update from windows 10 to 11 after the board and cpu update

running F63c which was the latest version as on Jan 22nd 2023. windows and GPU drivers are up to date as well

no haven't done that yet, but shouldn't be battery issue right since the motherboard is new?
ill check moving to another outlet soon... but this one has been working fine for years.
no on the tingling too, I'm guessing you're trying to check if its grounded, far as i know it is...

minor update, not sure if this helps but - after I posted this I restarted and got into bios where I got a pop up stating that the bios settings have been reset to default, (memory xmp were back to default, along with e few other settings)
