Motherboard

Hello,
My Gigabyte M/B will Power up for 20 - 30 seconds and cut out...it immediately powers up again and cuts out ETC ETC the sequence just continues..The monitor receives no signal ..The PSU is OK..(I have tried 3) its the Gigabyte GA-H55M-S2H Motherboard ..it apparantly does not complete the POST and one cannot acess the bios..Remove the single stick of RAM and the M/B recognises by a continuas beep it has no memory.. I wonder what next I can try??
