I recently bought a XFX Radeon R7 260x graphics card and due to circumstances, a Dynex 520 watt ATX power supply to accompany it. After putting the power supply into my computer, I am able to boot up and start everything normally with the integrated graphics. However, when attempting to boot up with the new graphics card, my computer produces six short consecutive beeps and my monitor is black with the "no signal input" message. The computer does not shut off by itself, and there is a red light on the motherboard. Please help.

Motherboard: MSI MS-7778
Power supply: Dynex 520-watt ATX
Graphics Card: AMD Radeon R7 260x
