Adjusted some BIOS parameters and the machine is no longer showing the screen.
Here are your details rephrased for clarity:
The system runs a Ryzen 5 3600 CPU, RTX 980 GPU, and is powered by an 80+ Gold certified PSU with a 750W rating. It uses an RGB MOBO-B550 motherboard running Aorus Elite OS on Windows 11 (64-bit). Storage is a 1 TB M.2 NVMe SSD.
I recently updated to Windows 11 and attempted to play Valorant for the first time. I encountered an error stating that my Secure Boot configuration wasn’t adequate for their Vanguard system. After following a guide, I tried enabling Secure Boot again, restarted the PC, and restarted Valorant, but the issue persisted.
I verified that Secure Boot was indeed enabled in the BIOS, though it wasn’t active. In the lower left corner of the BIOS menu, there was a note about ensuring another setting was activated. I found that setting and attempted to enable it, but nothing changed.
After saving changes and restarting, my PC powered on, yet no display output appeared. My monitors weren’t showing any signal, which raised concerns that something might be wrong. I’m worried I may have damaged the system and could need to replace parts, especially since the MOBO is known for being sensitive.
I’ve already tried troubleshooting: I powered off and on the PC, unplugged and plugged in the monitors and HDMI cables, reseated the GPU, shorted the pins to reset CMOS, and removed the CMOS battery. Each step was followed carefully to avoid mistakes.
I’m really anxious about this situation and hope I can resolve it without having to buy new components. Any advice would be greatly appreciated.
You didn't disable your PC's protection, but reinstalling Windows might be necessary. This is how I enabled Secure Boot. Here’s the full guide for installing Windows on an NVMe storage.
1. Ensure all SATA and USB devices are unplugged; only the M.2 drive should be active.
2. Navigate to BIOS settings, locate the CSM section and ensure it's turned off.
3. Select the Secure Boot option below and choose another operating system—avoid Windows UEFI.
4. Under Key Management, remove any existing Secure Boot credentials.
5. Use a USB drive with a bootable Windows 10 ISO that supports UEFI.
6. Press F10 to save changes, exit, and restart the computer.
7. Windows will begin installation using its built-in NVMe driver.
8. Upon rebooting, press F2 during startup to return to BIOS; your NVMe drive should appear in boot priority.
9. Revisit Secure Boot settings and set it to UEFI mode.
10. In Key Management, install the default Secure Boot keys.
11. Press F10 again to finalize installation.
After setup, power off the PC and reconnect any remaining SATA drives. If this reminds you of your initial setup, it could indicate an issue.
It seems you're having trouble seeing the bios information despite having a 1TB M.2 NVME SSD on your motherboard. You mentioned not knowing why it's not displaying and noted your storage setup. You're considering trying Lopj245's advice first, and if that doesn't resolve the issue, you'll explore the secure boot problem next.
Are there any debug LEDs active on the board? The next action will be to connect it outside the enclosure.
