There is no need to type in larger bold font. I won't get you help faster and it is a tad rude.
That said, have you tried letting Windows search for the driver itself? or is it just not showing at all (the Bluetooth) in device drivers? If it isn't showing at all, then it may actually be not working. But before going as far as to have the parts replaced I would start with first just rebooting (power fully off and then back on) the laptop and see if this resolves the problem. If not, Then let Windows search for the driver and see if it can find and install what you need. It doesn't have to be the latest one, just one that works.
Should that fail to resolve it, then try taking it to a tech.
