I'm using a HP Pavillion notebook and the laptop turns on I hear the fan, the caps lock flashes three times and the Wi-Fi light is on but the screen won't turn on.

You did not provide the exact model of your notebook.
Three blinks usually indicate a problem with the memory. First, try performing a power reset. Here in the link below, you can see how this is done:
Next, you should try reseating the RAM modules.
If you have more than one module, you should try each module in each slot and see if there is any problem with the RAM modules or slots.
If still not working you should try a different RAM module.
Hope it helps,

By reseating I mean the RAM modules. Depending on the model, there will either be a service door, or you will need to remove the bottom or top cover to get to the RAM modules:
So, you should remove and place back in again. If there are two modules, you can try one at a time in each slot to see if maybe one is defective and/or try with a known good module.
