I just got all my new computer parts for christmas, I built the whole thing, when I try to hook it up I realize I have no DVI slot. I used my dad's old graphics card before I could by the MSI AMD Radeon R9 270x. I plugged in a DVI cable into the graphics card, and my screen is all screwed up, and I can't change my resolution, all that comes up is "No AMD drivers or bad AMD drivers". Can anybody help me? The graphics card is Nivida GeForce 8400 GS (I know it's like 5 years old). But, my specs now are AMD FX Vishira 8-core CPU, 750 watt power supply, MSI mother board, and 8g's of Crucial RAM.
