I have a Toshiba Satellite m305d-s4829 that I purchased about 5 months ago. On 4 separate occasions, now, I have blue screened and gotten an error message that says drive_power_state_failure. In looking around forums and such, it is suggested that this is possibly a problem between Vista and my graphics card. Does anyone have any suggestions on whether or not this is actually the cause? Regardless, does anyone know how to resolve this problem? It keeps happening at the most inopportune moments, such as when I was taking an online final for a history class... Thanks!
