Serious bluetooth issues

I have some problems with my bluetooth equipment. I have had some of these problems for years. I have tried this, this and this usb adapter. I have tried these, these and these pair of headphones. I have tried this, this and this keyboard. It seems to be the same problems, more or less, with most of this equipment.

• Connecting my bluetooth headphones while playing a game causes the game to crash randomly sometimes, so i have to restart my computer to bring my desktop back again.

• Windows refuses to connect my headphones sometimes.
(Solved by enabling background intelligent transfer in services.msc.) ✔

• Windows sometimes asks me for a pairing code for my keyboard, without giving me a pairing code, basically preventing me from using my keyboard.

• Sometimes my bluetooth headphones refuses to connect automatically. I have to go to control panel, click sound and right click on the headphones, to connect them manually instead.

• Sometimes there's no sound in my headpones if i power them on while playing a game. I have to restart the game to bring the sound back again.

• Connecting my headphones while watching a video on youtube causes the video to crash, so i have to reload it again.

• Sometimes i get this message, if i try to send a file from my computer to my phone.
(Solved by right clicking the bluetooth icon in system tray and clicking send file.) ✔

• If i send a file from my phone to my computer, it says that the file transfer failed, without giving a reason.

You say this has been happening for YEAR'S? If its been going on for that long I would have to think its related to your motherboard. Might be time to get a new machine. Does it do this right after a O.S. install or re-install? Have you tried uncoupling all your Bluetooth devices and recoupling them? Have you updated your BIO'S and/or chipset? You could try a system file check, but if its been going on for that long I really think it's probably organic in nature.

Some system spec.'s might help us to determine any other causes ...........

Yes, it also happens after reinstalling windows. I have tried unpairing and pairing my bluetooth devices many times. I have the latest chipset drivers. I have tested this with several computers and the problem is the same. I have also tried doing a system file check, but it didn't solve any of the problems.

I think i may have solved some of the problems by disabling the realtek high definition audio drivers and nvidia high definition audio drivers from device manager, as well as disabling my headphones from recording devices. It seems to be crashing a lot less than previously, but it still crashes occasionally.

You should be able to disable the sound adapter built onto the motherboard via a setting in the BIOS. I know the computers I've had to deal with and their onboard Ethernet/NIC adapters had that setting, useful when using an add-in card instead, kept Windows from finding the onboard.

I checked my bios, but i don't see any options like that.

Is it possible to simply disable the passcode, so i can connect my keyboards without it?

Yes, but that doesn't really help if i can't see what the passcode is, thus making me unable to connect and use my keyboards.
