Help! My computer randomly shuts down!

The past week and a half or so, my computer will randomly shut down. It says something about a failure of RPC (Remote Procedure C… something) and I think I once saw something about Win32, as well. It will just pop up with the RPC failure notice and then it will have a one minute countdown before it just re-starts the computer.

My computer is a relatively new (4 mos old) Sony Vaio PCV RS100.

Does anyone know what could be causing this? What can I do to stop it?

D’oh, there’s another post about this in GQ already. Nevermind.

Yep, see here:
