Remove the graphics card and plug your monitor directly into the motherboard VGA or DisplayPort. Boot into the BIOS, check if your primary video adapter is set to "PEG" (PCI Express Graphics), and verify that "CSM" (Compatibility Support Module) is enabled.

The manual spec limits you to (2x8GB sticks). If you install 16GB and the system only recognizes 8GB or fails to boot, ensure you are using standard voltage (1.5V) DDR3 memory. Many high-performance gaming RAM sticks require 1.65V, which this board may not support stably. Includes a PCIe x16 slot for dedicated GPUs,
