I have a laptop whit a pentium dual core and a Nvidia gpu. I think a 550M. This is my secondary laptop, and I am trying to install steam. But it says that steam needs to be online, and that I am not connected to wifi. Well I was connected. I am trying to install CS2 on this laptop. I have a Toshiba satellite 750-1nm. Is this laptop capable for CS2? and how do I fix this error?
