I already had the tabs open which a simple search brought up, so I'll share 
that. There are no guarantees in life, so I suggest to just try things out. 
Which is rather common/normal in troubleshooting issues.
No guarantees, but there's little chance the device blows up or catches fire...

and my own educated guess: Disable the ASPEED device and see what happens ...
