PC not posting after changes to BIOS!!!

[arcoons]

Hello! As my final straw I decided to come here for help.

I recently made the decision to tey to switch to Windows 11. Upon doing so everything went smoothly until I decided to try Valorant. I recieved an error which I found out could be fixed by disabling CSM in BIOS and putting Securw Boot to Standard. 

 

After doing so my pc decided to not post anything anymore. All I can say is the pc turns on and all the light nd stuff works except I'm getting a black screen also a weird thing I noticed is my only fan connected to the motherboard and my gpu fans ramp up and then ramp down in intervals.

 

I've tried everything in my power such as clearing cmos by shorting pins and removing the battery. Trying to clean ram sticks and booting even with them separately. Reseating gpu, booting without hard drives.

 

Would anyone know a solution possibly? Or the better choice to take it to a technician for a diagnosis?

which pins exactly did you short? and was the psu unplugged from the wall when you removed the battery? i would try again with the battery out and psu unplugged for 5-10 minutes for good measure.

what are the full specs of your pc?

Clear CMOS, and that should do it.

Refer to your motherboard manual for instructions on how to do it properly. Each motherboard is a bit  different.

 

The issue is that CSM cannot be "just disabled"

When CSM is enabled, it makes your UEFI simulate the old BIOS of ages ago, for legacy hardware. The issue is that BIOS can only support MBR formatted drives, and UEFI can only interact with GPT formatted drive.

 

The drive must be either:

• wiped and start fresh (backup your stuff first)
• converted right before switching (backup your stuff first, as failure will make your drive data unrecoverable... well it will be very hard). Microsoft made a nice tool for doing this, it is in Windows, it's called mbr2gpt.exe. They are a few tutorials on this very forum.
