So I got my new pre-built computer from AVADirect today and there's a problem. I'm currently using the on-board video but Windows and the CC install doesn't seem to detect my 4850. I've made sure the card is connected and all the power supply connectors are snugly plugged in. Can anyone help me? Today's my birthday and this was my big present. 
I'm using an HDTV/Monitor connected with DVI. Max res is 1280x720. Oh and the fan is spinning.
