Windows 7 Random Blue Screen

[Canto 34]

Started 2 days ago and it has happened twice. When it happens, my screen freezes and there is usally a very obnoxious beeping before the blue screen appears. Not sure what may be causing it, it lasts around 30 seconds, it shuts down my computer and then when I turn it back on, everything is completely normal. Cleaned my computer, scanned for viruses+malware, nothing came up.
