A 3:2 error code is a memory problem
Search online for "HP Pavilion 15 CC (insert model number) service manual" to find the manual,
This will show how to correctly remove the modules from the motherboard.
Remove the modules and then reinsert them again and see if this restores the laptop.
Follow the instructions especially about disconnecting the battery before starting further inside the laptop
If there are 2 modules and it still doesn't work try installing only one and try. If still no good try the other. If still no good try the different slots in case one is faulty. Try each module in each slot etc.
