New Rog Strix B550-F Gaming WIFI II booting to bios

[Orpheus1942]

Can some please help desperate I have tried loads of fixes but nothing works I am im 80s and really need my PC

Installed a Rog Strix B550-F Gaming wifi II and it was fantastic (FOR A WEEK) and then one morning I turned it on and it booted straight into the bios and carried on doing this for 2 days, and the third morning I thought I would try it ( MORE IN DESPERATION ) and it booted up to Windows 11 just fine and very fast and all working just brilliant, so that night I put the PC in sleep mode (INSTEAD OF TURNING IT OFF) and when I woke it up the next morning it booted straight into the bios again very frustrating, so I turned it off had a cup of tea to relax the stress and 10 mins later went back switched it on and it booted strait to my Window 11 24H2 and all works fine again hence I can compose this. So as you can see this is a intermittent fault and and very annoying.It has the latest bios update 3611 and Windows II 24H2 and all drivers are up to date.

Hello Orpheus1942

Some things I'd check:

In the bios, on the Boot tab, that your windows boot drive is set as Boot Priority 1. It should show "Windows boot manager" in front of it. Also check that CSM is disabled.

If that's all good or didn't help:

AMD motherboards seem to be more susceptible to the windows fast startup feature, you can try turning this off.

Power options, "Choose what the power buttons do", 

Click "Change settings that are currently unavailable".

Uncheck Fast Startup and click Save changes at the bottom.

If none of this is helping, try resetting the bios to defaults. In the bios hit the F5 key.

 I came across a thread where corrupted security settings can cause what you're experiencing, the solution seemed to work.

Hi Nate 152 thank you for your kind and very prompt reply. I have done what you have told me and changed the power settingbut but have not tried to restart my PC yet as concerned it will boot into the bios again and I wont be able to get out of it. I left it on last night and all good  this morning (It runs like a dream). I have read the link that you have sent me and that gives me a bit more confidence to restart,  or do I just return the MOBO and ask for a replacement?? My son will do all the necessary work. And as for doing a MB reset will F5 really do that because I read somewhere that I had to short out to pins on the MB to achieve that is that correct? Sorry I am not very technical.

Be sure to disable EXPO whilst you're testing this to rule out overclocking instability.

Thank you Silent_Scone but what is EXPO????

[Orpheus1942]

OK now know what disable EXPO means

hi Everyone - this is the son of Orpheus... (sounds like a game of some sort)... anyway.. firstly thank you all for helping my dad out. For 82 he sure does know his way around a pc.. So after much messing about the following seems to have resolved the issue but I cant put my finger on why.

I have swapped the M2 boot drive to the other position.. it was originally nearest the CPU but moved it to the other position and so far... boots every time with no issue and no errors. this either means that the M2 slot nearest the CPU is faulty or that the actual M2 is faulty.. i guess if the issue starts up again in the other slot then the M2 is faulty and the mobo is ok.

Currently. its working! ... so Dad.. dont touch it ok!

Thanks everyone.
