Can we get more information? What have you tried so far?
Try testing each part out individually:
1 stick of ram at a time
don't use gpu
take mobo out of case and start by shorting it with a screw driver
try a new psu if you have one

This indeed sounds like a PSU issue.
You havent listed one, which leads me to think you might have neglected something as important as enough power.
Also go over all the power cables from PSU to your motherboard, and make sure you have all power cables plugged (some motherboards has an extra power cable for CPU power).

It could be so simple that your PSU is unable to deliver sufficient power.
But atleast it sounds like a power issue.
