1 long + 2 short and no POST = dead video? Happening with my new Gigabyte GA-MA78GM-S2H 780G mobo. Had been working just fine for a month or so using the onboard video.
Tried putting in a PCIe video card but the only spare I have uses an aux power connector from the 4-pin molex and when I plug it in the system won't boot. Think the PSU (300W) is not beefy enough. Without the aux power the system boots but still gives the 1 long + 2 short beep and no POST. ---- Brian
