Question PC randomly boots to the BIOS ?

[refmon]

Hello all,

Maybe 2 or 3 times a week, my pc will boot into bios on its own. If I exit bios windows 11 then boots up normally but I have no idea why this is happening. I thought this could be a RAM issue but I just upgraded and it's still happening

Update your post to include full system hardware specs and OS i nformation.

Look in Reliability History/Monitor and Event Viewer.

Either one or both tools may be capturing some error code, warning, or informational event showing some failure to load Windows when the pc appears to boot into bios on its' own.

How do you normally shut down the pc?

Specs
Mobo: B550 TOMAHAWK
CPU: Ryzen 7 5800X3D
GPU: 4080 RTX
RAM: 32GB Dual-Channel DDR4
PSU: EVGA Supernova 750W

In event viewer I found the previous shutdown was unexpected, failed fast startup and The system has rebooted without cleanly shutting down first errors but I always turn off my PC normally through the start menu.

failed fast startup

If it's failed Fast Startup, try disabling this function. I disable it in all my systems.

Are you running a high XMP overclock which might be crashing the computer? Run a full MemTest86 test (boot from USB) to check memory stability. This could take several hours. If there are any errors, reduce the XMP overclock speed.

Thanks, I'll see if it still happens with fast startup off.

I'm running XMP but I did that with my old ram on and off as well.

It just booted into BIOS again but outside of reinstalling windows, I'm not sure what it could be.

I ran memtest86 and it came out error free

but outside of reinstalling windows, I'm not sure what it could be.

When I'm in doubt about the viability of a Windows OS, I disconnect the suspect boot drive, grab a cheap SATA SSD and install a new copy of Windows on it. Takes around 15 minutes to get to the Windows Desktop. Slowly install apps and see if the machine crashes. It can take several hours, but if the PC hangs in the same manner as before, it points to a potential hardware problem or a BIOS setting needs adjustment.
