DMA is located in the Hardware Resources category in System Information. It displays information about your system's direct memory access (DMA). DMA transfers data between system memory and hardware devices without passing it through the CPU. The Resource column in the details pane displays the DMA channel that is being used by the device, which is listed in the Device column. The Status column displays the status of the device.
If the Status column indicates an error, such as Error, Degraded, Unknown, Pred Fail, Starting, Stopping, or Service, you can try the following troubleshooting solutions:
- Use Device Manager to locate and troubleshoot the problem.
- Contact the device manufacturer to obtain an updated device driver.
- Reconfigure the settings in the system BIOS or EFI.
