|I have an HIS Radeon 6870 graphics card, a Corsair TX650 PSU, and an Acer 21.5" monitor. Long story short, I plug everything in and get a "no signal" message on the monitor. It recognizes that i plugged in a cable from the monitor to the card. Both 6pins are in the card, and the card is securely mounted on the motherboard.|
I'm building this PC, so there's no OS on it yet. The AMD motherboard has no video of its own.
- The fan on the 6870 spins, so it's definitely getting some power.
