Lack of power to the graphics card, display flower screen

As long as the video card connected to the external power, the computer turned on the display screen flower. If the graphics card does not connect the external power supply, the computer can be used normally, but the system is running, the video card is not enough power. Plug in the graphics card in other computers, connect the external power supply and normal use.

This may be caused by instability of the motherboard voltage output. Users can enter the BIOS in the Advanced BIOS features Setup interface after power-on, which has an AGP VDDQ voltage option, which controls the motherboard AGP port voltage output and should be set to 1.50V. If the default value is 1.50V, you can try to increase the voltage to 1.60V.
