Recently, I bought 2 8GB Kingston RAM sticks and a Sandisk Extreme Pro SSD and replaced them with the existing parts in my laptop. After this upgrade I'm able to turn on the laptop, but I get no screen input. The laptop fan runs for a couple seconds and I'm able to open the dvd drive, but nothing is happening on the screen. After 10 or 15 seconds, the laptop reboots and repeats the process. When putting the old ram back in nothing happens either. Do I need to reflash my BIOS or something?
