I bought a RX 480, I installed it right on the power cable ... But 10 seconds after the windows start the computer "freezes" in the image that was, it simply "hangs" everything. My attempts to repair: Reinstall windows, try other versions of windows (7,8,10), reinstall the card, test versions of older drivers, decrease the rpm of the card, and nothing helps, I hope someone can help me, Plate is new, I bought new from the store, and still could not use.
