Have you restarted the computer since the issue happened?

Did you change anything, such as install drivers or programs or do a Windows Update, right before this happened?

Do you have a DVI to HDMI adapter on hand? You could try putting that adapter on your 6870 and hook it up to your TV to verify it isn't the HDMI port on the TV. Or have you tried using a different HDMI port?

Try doing a system restore to some time before the Windows Update.
