Hi, from your description it appears your power supply is ok.
Remove your RAM chips, clean everything with a soft brush or a can of compressede air [from computer store] Reinstall the RAM making sure it is seated firmly.
If this does not solve the problem, Are you using 1 or 2 RAM sticks? if 2 then remove them again and swap them around.
stick one in dimm2 and stick 2 in dimm 1.
If you only have one stick then beg or borrow another stick and try it. If all fails you may have developed a mobo problem.
