I am running an ASUS M2N32SLI Premium. I have already tried the checklist to no avail. Both video cards are working, I tried them seperately as well. The PC6400 OCZ Gold Edition RAM sticks were all tried seperate and paired. On power up CPU Fans spin, green light on mobo lights, but no post. Cleared CMOS twice. Checked all power cables and mobo cables, all are plugged in correctly.
