Question Unknown Boot Problems

[Tucker86]

This morning i went to boot up my computer, during the post process all my peripherals disconnected & became unusable.

MOBO: Asus Strix B450F
CPU: Ryzen 7 2700x
GPU: RTX 3700Ti
RAM: 32GB 2666mhz 4x8GB
PSU: Corsair 750W
OS: Windows 11


After quite allot off attempted troubleshooting I found by resting the CMOS & removing 2x Ram sticks I could get it to boot to the BIOS.

1)Power system on & boots.
2)Press F1 to run setup, change low CPU fan speed, Save & Exit.
3)Loses signal with all peripherals.
(Had to remove the cmos battery as this is the only way I can seem to boot up fully).

After repeating the same process a second time round, and rather than changing any BIOS settings I just exit the BIOS and the system will boot to windows and work just fine.

So I believed this to be a problem with my Ram as removing 2 of the 4 sticks would somehow get me to boot performing the previous steps. But after testing all 4 sticks in different formats in the channels 1-3, 2-4, 1-1-1-1 I can’t seem to find any issues with an independent stick and this issue still occurs anyway. Further more as soon as I change any settings in my BIOS the whole system just shuts of a posts taking me back to the original steps, making me believe it could be a more complex issue?.

Any help greatly appreciated as I have trying to fix this myself now for some time today, would this require further diagnostics.

As a matter of elimination try a new CMOS battery.

You haven't experienced any power surges, lightning storms, ect recently have you? Brown outs? Flickers? How stable is power in your area?

Not that i am aware of at least the power grid in my area is fairly stable and we are warned of any 'planned' power outages in advanced.

Have ordered a new battery and hopefully this will help, but until it arrives I wont know for sure.

You can pick up a CR2032 from just about anywhere, you know.
