After having no problems for a year with this build, I now have no video or sound during post. Below is the observed behavior which has been consistent since the problem started last week. 1. When connected via DVI to Asus VW246 there is no video or sound during post. Video and sound display normally after Windows7 starts. 2. When connected via DVI-HDMI cable to Hanns-G HG281D monitor there is no video or sound during POST as well as no video when Windows7 starts. I have quiet by accident found that If you restart then video will display normally after Windows7 starts the second time. 3. I have attempted each GTX 260 Video Card seperately as well as SLI Windows7 Professional Two(2) GTX 260 Black Edition video cards Hanns-G HG281D monitor connected via DVI-HDMI cable Asus VW246 monitor connected via DVI Corsair HX 1000 power supply Please give me a direction or a reccommendation!!
