First of all, check the memory modules. It’s likely that when you dropped the laptop, the memory module got dislocated and now it’s not making a good contact with the motherboard.
Reseating the memory module might fix the problem.

My acer laptop
cooling fan making noise and can you fix. how can i make the noise stop.

If the fan started making noise, I guess it’s time to replace the fan.
On some Acer laptops the cooling fan could be accessed from the bottom.
Take a look at the Acer Aspire 5100 disassembly guide for example. The cooling fan is removed in the step 5.
