Laptop not booting up after Ram upgrade

[miskas3]

So I have seen various online videos about taking battery out and everything but nothing has worked so far. I dont even get the ASUS logo. My laptop keyboard just lights up and the fans go superfast. That's it. Absolute no activity in the screen. My model is FX505DY. Original Ram is 8GB. New one is 16GB. p.s. Both slots are fine (checked with the original one) I have also tested with the new Ram alone just in case it's a mismatch with the original one

Hi @miskas3 ,

If you replace memory modules with different capacities or from different brands, your computer will need to perform a complete memory training during the next startup.

During the memory training process, your computer will not display any visuals, and the training typically takes about 1 to 3 minutes, depending on the size of your computer's memory.

During this time, please ensure your computer is connected to a power source and refrain from forcibly shutting it down. Let your computer complete the memory training on its own, and wait for the display to appear. Please give this a try, and if you have any further concerns, feel free to let us know. Thank you.
