PC remains unresponsive during startup following a BIOS upgrade.
Following the BIOS update from F41 to F66 I’m stuck on the boot screen. Can’t enter BIOS or Windows, no way to press delete or any key. Peripherals aren’t working either. If I connect the keyboard before turning on the PC, the LED lights up. But when I unplug it and plug it back in while the system is running, the LED stays off. The VGA debug LED is active. I’ve tried resetting CMOS multiple times, booting without any drives, using just one RAM stick, and even trying to manually enter backup BIOS on this board—no success. Any ideas? Thanks ahead. My specs: Windows 11 B450 AORUS PRO (updated from F41 to F66, latest), AMD Ryzen 5 3600 RTX 2070 Super, 2x8GB DDR4 HyperX FURY at 3200MHz).
You cleared the CMOS by removing the battery and ensuring the PSU switch was off. After holding the power button for a few seconds, the motherboard fully discharged. The VGA LED remained on, so you might have re-seated your RTX 2070.
You might have updated unnecessarily since your system could still be functional. Make sure you review the BIOS details carefully. There could be compatibility problems with RAM or BIOS settings, as seen on older boards where waiting longer or resetting to a previous version helped. Don’t assume it’s permanently broken—sometimes patience and proper steps resolve the issue.
They attempted it several times in both directions without success, followed all the steps mentioned, and the GPU was positioned behind the CMOS battery. It’s possible the issue stems from a dead CMOS battery. Thanks for your effort!
Attempted an update due to Riot Vanguard causing crashes while playing League. The situation worsened after uninstalling, leading to a BIOS upgrade being considered. Upgrading the BIOS might have helped, but I’m hesitant now. The latest version supports the CPU, yet I can’t reach F41 because of BIOS issues. Yesterday I left the CMOS battery out for two hours and discharged the capacitors—possibly it’s damaged. Uncertain if it was my mistake, but I think I followed the steps right. It might be time to replace the board. Thanks for your help!
Sure, updating the BIOS can sometimes resolve those intrusive cheat programs. It might sound like the anti-cheat caused a system failure, so consider installing a clean Windows version first before replacing your hardware. This could be due to a hardware issue, but it seems like a coincidence that problems appear right after "vanguard" breaks. If you haven’t tried a fresh install yet, do it now.
