I get no display when I turn on the PC, no beep codes, the power supply light is a solid green and never turns off.. used a different power supply even but still nothing worked. For the first time of turning it on it turns it self off from within 10-30 seconds. but after turning it on again after that happens, it stays on but with a solid orange power light and no display, any suggestions on what it could be? Also I tried both DVI for the gfx card and VGA for the integrated, neither work.
