SHANGZHAOYUAN LGA 1155 Motherboard B75 for Intel 2th/3th Gen i3,i5,i7/Xeon E3 12XX V2 Series CPUs, DDR3, NVME M.2, PCIe X16, 100M LAN, VGA, HDMI-Compatible, SATA 3.0, USB 3.0, Gaming PC Mainboard

• Computer won't start, fan doesn't spin, indicator lights are off

  Check CPU compatibility or damage; check motherboard and CPU power supplies; check power button cable; check power switch on; check power supply; disconnect graphics card, hard drive, USB devices, etc., then try powering on again; clear CMOS.

• The fan spins briefly and then immediately shuts off, or the computer repeatedly restarts

  Clear the CMOS; check CPU and memory compatibility or damage; disconnect the graphics card, hard drive, USB devices, etc., and then try powering on.

• The fan is spinning, but pressing the Caps Lock key on the keyboard doesn't activate the indicator lights

  Try clearing the CMOS; checking that the motherboard and CPU power supplies are properly connected; checking for CPU and memory compatibility issues or damage; and checking that the memory is installed correctly.

• The fan is spinning. Pressing the Caps Lock key on the keyboard illuminates the indicator light, but there is no display

  Check if the monitor and display data cable are properly connected or damaged. If using integrated graphics, ensure your CPU supports it. If using an external graphics card, connect cable to GPU output; Verify the graphics card functions normally.

• Blue screen, system crash

  Check if the CPU cooling fan is spinning and if the cooling fan base is properly seated on the CPU; replace the CPU, memory, hard drive, operating system, and power supply.
