Hi, I have a tsunami speeder 259 and recently i install windows vista ultimate x86(32 bit). The problem is when i install the geforce go 6600 driver for win vista after the instalation gives m a blue error! This labtop has a particularity:the vga extension, that can run ,if on, the ge force and if it is off, the intern graphic board. I think that the problem is based on the vga extension. Anyone can help me? Sorry the English speach.
