I have a 650w power supply. Asus p5q pro turbo motherboard. 2g ram. intel core 2 quad 2.66gh processor. i bought the motherboard and processor recently and had trouble with the processor before and sent it back to get a new one. i have everything plugged in but i cannot get any video to display. i have power to the motherboard and i took off the heat sink on the processor to see if it would get warm and it did so i am pretty sure it is not that again. please help, idk what to do.
