My computer (etower|633ids) has an hibernation feature. To
bring it out of hibernation you must first press a green
oval button located on its tower. For the past couple of
months, a message has appeared shortly after returning
from hibernation;

Xupiterstartup has caused an error in <unknown>.
Xupiterstartup will now close.

If you continue to experience problems,
try restarting your computer.

I would close the window and restart my computer, but the
message would still appear (Although, it doesn't for at
least one or two hibernation cycles after).

What do I do to prevent receiving this message?

Any help you can provide will greatly appreciated.
