i found out what was the problem.
the problem was a trojan/malware w/e
called regsrv.exe that was stored in my:
c:\windows\system
that created a process called:
stdrt.exe
and it's files were on:
c:\windows\Temp
that shit was 24/7 filling my bandwidth downloading things and started playing music by herself LOL
