Solved Problems after Log On - unknown dispositives connected - Soft or Hard?

[greatfinale]

Hey people, Im not sure that if it is the right place to open this thread, if not please move to certain spot.

After formatted PC one week ago and installed some programs, windows began to produce two sounds of "dispositives/drives right connected" right after the log in. I already tried everything and cant discover the sources of theses sounds and who is the culprit (software or some hardware).

-Tried to unplugg ALL USBs before turning on and the problem persists;
-tried to unplug some sata and usb from mobo itself;
-Tried to turn on and turn off all the aplications the are turning on with windows, including unmount (daemon tools) any virtual drives (except the one created by seagate for my 3TB HDD)
-**Discovered one Unknown device in the device manager, but no lucky desativating or deleting him (always back on system start up)
-tried to solve all log event problems, only stuck in the VdiskBus error that occurs in windows startup (and Im already tring to solve that in the specific area - crashes and debugging);
-and maybe other things that I dont remember now.
... with NO sucess.

I turn on windows, there is logon and, ~bululum~ the two consecutives sounds are there.

Maybe some of you guys can help with some other ideias, or places where I can discover the last recognized/plugged devices or things like that.

after a lot of time trying, I tried to disable my bluetooth devices (mobo integrated), and now the two sounds are gone.
Problem solved after more than 10 hours trying everything.
