Hard drive buzzing and shutdown

[Luxa]

so i messed around with my hard drive and added some more ram but now everytime i turn it on it makes a small buzz and then turns off.
The screen is black
Nothing to do with battery
Laptop is a Acer Extensa 5235
I have swaped the hard drive many times the only diffrence is there is no buz when i turn it on.
Please help

Step 1 would be to undo your changes and see if the laptop works normally again. If it does I suspect your new ram is incompatible.
