Hey guys, I'm not sure if this is the correct category, but I missed any category of troubleshooting, if any. Anyway, some time ago my computer started getting errors 0xc000007b in the beginning, at first by the Realtek HD Audio Manager and On-Screen Keyboard (RAU64 [or so]. Exe and osk.exe). I soon realized that I could open the Windows calculator and Sony Vegas Pro Since I can not use the Realtek audio manager, I can not change my audio options via the control panel (I think that is why , at least). So I went to reinstall Windows as I was looking for some kind of problem in this regard.
