I purchased the computer from someone else and it came with Windows 10 already installed. After trying to install graphics drivers, the system crashed and became unusable. I reset the operating system, but access is blocked—either a password is required or it seems Windows might be corrupted. There’s no safe mode available. Can I reinstall Windows without a product key?
Based on the board's age, you might be able to reinstall the operating system without entering a product key since newer models embed it into the BIOS.
It should have come sooner, but UEFI came later than LGA 775. I was mainly using Intel Core i9 from the second and third gen Sandy Bridge and Ivy Bridge chips, where there was a major move from the old BIOS to UEFI.
You can try logging in using standard user accounts or temporary admin rights. If no admin accounts exist, you may need to enable local administrator privileges or use a recovery option. Regarding resetting Windows without admin access, some features require elevated permissions, so alternative methods like system restore or manufacturer tools might be necessary.
I’d prefer a fresh start. Try another machine and create a USB drive. Be ready to erase everything if you want that. If you go this way, Microsoft records your Windows 10 license code linked to your device ID on their servers. When you reinstall, just pick “No product key” during setup and the activation will happen when you connect online.
You won’t have a working copy, but it seems you can still get Windows without the activation key. I’ve done this before—used a key at some point.
