Why won't my laptop turn on or charge after a RAM upgrade?

Hello,

I own a E5-571G-750T. Recently, I purchased 2 8GB DDR3 1600 MHz from Crucial, opened up my laptop and replaced the existing 4GB RAM with them.

My laptop was turning on fine until moments ago when I tried if I could play DotA2 on high settings. Suddenly, there was a small pop sound and my laptop died. I tried re-booting but to no avail. Even when plugged in, there’s no light indicating it’s charging.

Desperate, I opened it up, removed the RAM sticks, then put them back. I also tried tightening some components. Didn’t work.

Also tried a Youtube tutorial where I had to press the power button for a full minute, but it didn’t work either.

The only thing I haven’t tried is switching back to the 4GB RAM or interchanging the 8GB RAM in the slots. Is there even a point in trying? Or, could the problem be unrelated to the RAM upgrade?
