I just finished putting together a new computer, and after trying for several hours, I can not get a display. I've confirmed it's not the graphic card (had it tested it another PC). All the LEDs on the case light up and all the fans spin when I turn it on, but no display. Interestingly enough, a red light comes on instead of a green light on the front of the case. Computer Specs: NZXT Apollo Case i7-860 Quad Core @ 2.8Ghz ATI Radeon HD 5870 (1 GB) Video Card OCZ StealthXStream 700W Power Supply G.Skillz Ripjaws Memory (Dual 2GB x 2) Asus P7P55-M Motherboard 1.5 TB Seagate Barracuda Hard Drive (7200RPM) Any help would be appreciated.
