Can you elaborate and explain don't find where in download support center is it?
What do you mean by "i don't know which driver i need to download"
Check your windows update and check system update via My Asus
You will see if any new update is available depending if your system have old version and not updated to latest or recent.
If you are facing issue with software or hardware kind of errors Just go to device manager and check if it shows any driver errors. From ther you may find what you need to fix or update.
