I am about to upgrade my gpu for the first time tomorrow and I decided to give my PC a bit of a cleaning beforehand. my friend and I basically just went over everything with a normal can of dust cleaner without removing much inside the rig. but we did take out the cpu cooler and cleaned it more thoroughly. When I put everything back together and booted up everything seemed fine but I discovered that my PC is no longer able to connect or properly recognize Bluetooth devices. It also seems to be having trouble detecting the drivers for my wireless keyboard but that still works just fine.
I have tried connecting several different devices with bluetooth, all with the same result - the search screen shows one or two "unknown device(s)" and doesn't do much else. I have updated my driver's, uninstalled and reinstalled Bluetooth, and restarted my PC several times. I am but a layman when it comes to this sort of thing and this was my first time really attempting to mess with the inside of my PC since I got it. Not really sure what the issue could be at this point but I wonder if it had anything to do with us removing/cleaning the cpu fan incorrectly, or just some stray dust that made its way to the motherboard..
Any help or input would be really appreciated. Thanks :)
