So my laptop had recently not turned(blue light lite, no sounds, no black backlit screen on) on so I figured it was the graphics card, so I ordered a new motherboard(graphics card was soldered to motherboard) and when I swapped out the motherboards, The laptop had worked. About 30 minutes later, It unexpectedly shut off. I tried powering it back on and I heard the hard drive and the fans start to run for half a second and shut off.

So I know its not the graphics card, cpu, or the motherboard that is at fault. Could it be the RAM preventing boot up? Im very stumped at this...
