Hello
I understand that you’re experiencing multiple issues with your PC. Let’s address them one by one:
PC not shutting down completely: This issue could be due to the “Fast Startup” feature in Windows 10, which is designed to help your PC start up faster after shutdown. However, it can sometimes cause problems with shutdown. You can disable this feature by going to Power Options > Choose what the power buttons do > Change settings that are currently unavailable > Uncheck Turn on Fast startup.
Black screens during gaming and video streaming: This could be due to outdated graphics drivers, a problem with the monitor connection, improper power-saving settings, prolonged hardware stress, excessive heat generation, or misconfigured game settings. You could try updating your graphics drivers, checking your hardware connections, adjusting power settings, and monitoring system temperatures. If the issue persists, it might be game-specific, in which case repairing game files, updating the game, lowering the in-game resolution, and changing other graphics settings might help.
Failed BIOS update after factory reset: If a BIOS update fails, it’s usually because the wrong BIOS update was attempted, or there was a power interruption during the upgrade. In your case, since the Dell G5 5000 System BIOS update is not registering, you could try the following steps:
Ensure your motherboard or laptop supports a BIOS auto-recovery feature. If it does, use a working computer to download the latest/compatible BIOS file. Copy the content to a USB flash drive before inserting this into the problematic PC. Start/restart your PC and this takes you to the flash utility, where you can proceed the same way you had updated the BIOS before.
If the above step doesn’t work, you could try to perform a system restore or reinstall Windows.
If your PC is not able to complete a prompted restart, it could be due to various reasons including software conflicts, hardware issues, or corrupted system files. You could try running the Power troubleshooter, performing a clean boot, booting into Safe Mode, or resetting your PC.
