code 12

About this tag
Code 12 is a Windows Device Manager error indicating that a device cannot find enough free resources to use. This typically occurs when two or more devices conflict over the same I/O memory, IRQ, or DMA channel. On WindowsForum.com, users report Code 12 for various hardware including secondary GPUs, network adapters, sound cards, and integrated audio. Common causes include upgrading from Windows 7 to Windows 10, installing new hardware that conflicts with existing devices, or BIOS/UEFI resource allocation issues. Troubleshooting steps discussed include disabling conflicting devices, updating drivers, using DDU to remove GPU drivers, and checking BIOS settings. The error can affect both desktop and laptop systems, often requiring manual resource management or hardware reconfiguration.
