It sounds like somthing more to do with your computer rather than the game/client
Can't be sure exactly but either your soundcard is starting to brake or you could have some binary errors or possible some general software/OS issues. But i'm pritty sure it's not the client. As of the 2 errors Windows has a serious error and Generic host 32.
Edit -
Apparently this can fix the Generic host 32 error
1.Click ‘Run’ (or hold windows button and press R) Then type ‘Regedit’ and press enter.
2.Navigate to:
HKEY_LOCAL_MACHINE > SYSTEM > CurrentControlSet > Services > Browser > Parameters
3.Find the Key Name: IsDomainMaster,
and set Data: False
4.Restart Your PC
