Sonic,
You likely have either a dual core CPU or a Hyperthreaded CPU. Either one
will show up as two logical processors in Windows. So, there is no processor
to uninstall from the device manager.
Is there a particular application or program that you are using when your
system crashes? Sometimes games do not go well with dual core or
hyperthreading. I can't recall for sure, but there is a way do disable
hyperthreading or the second core in a dual core CPU from the task manager.
Maybe, poke around there and see what you can find.
