My daughter recently started getting a BSOD on her Dell Inspiron laptop with Windows Vista Home Basic installed. The error message is pointing to rdbss.sys but I can’t find anything that is relevant to a fix for this. I eventually reinstalled her machine from a factory backup. Subsequently, I have an Inspiron 530 with Windows Ultimate installed. Recently it started rebooting on its own with no errors. I discovered after much frustration that it had something to do with having dual monitors installed on my nVidia card. I disconnected one of the monitors and it seemed to work fine for awhile and now I am getting the BSOD with the reference to rdbss.sys. Is anyone else having this problem and does anyone know of a fix for it? Dell support has been totally useless.
