My XPS720 works fairly well apart from a little disturbing thing. It does not always start.. It goes past post but stops dead just before the point I expect the DVI symbol to appear top left and the Vista orb to appear. Just stops black. I get nothing in any logs and no error message. I have updated all my drivers, GPU several times. No difference. My RAM is fine. Anyone able to suggest how troubleshoot a problem like this one?
Are their any "Diagnostic Lights" on when it does not boot? See link below.
Have you checked "Event Log" in System Setup (Bios). To enter Setup press F2 at the dell screen.
