Hello Jesus_
You can start with checking the RAM sticks and RAM slots one at a time. That is, install one RAM stick and check if the laptop turns on properly. If it doesn't, pull the RAM out and install the second one and then check again. You should try this with both the RAM slots.
If this doesn't help, try powering on the laptop without the CMOS battery.
If the problem persists, you can try hard resetting your laptop. The instructions to do so are given below:
> Unplug the laptop from its power adapter.
> Pull out its battery. (Not the CMOS battery but the one that powers on the laptop when it is unplugged from the power supply.)
> Press and hold down the Power button for 45-60 seconds.
> Release the Power button.
> Put the battery back in.
> Try to start the laptop now.
Feel free to reply if more assistance is needed.
Cheers!!
