thanks for that, but i did all of this yesterday. 3 checks in total. I have the motherboard out of the case and have tried the power as well. only getting the same response. only 1 second start then shutdown with the ram in.
When you say you "have tried the power as well" do you mean you have tried a different, known-working PSU? Please explain.
Also - a very long shot - please check your cable from whatever graphics adapter you are using (please let us know) to your monitor, and the monitor itself. Two weeks ago we actually had a PC that failed to boot like this until we replaced the DVI cable with a DVI-to-VGA adapter and connected the PC to the VGA port on the same monitor. Apparently a short somewhere (DVI cable or DVI port on the monitor) caused the PC to shut down immediately.
I have tried 2 different PSU's. Both brand new, both different brands. Both gave the same problem. motherboard starts for a second then shuts down. I have read about people with voltage and ram but changing it in bios. Would be nice to even see bios...
As for Video card, i have not even had it in as yet, but it is an old geforce card from about 4 years ago.
