I just installed HL2 on my laptop, it started and ran well (actually not too well, because the laptop is for office use, but ok) until I got to an autosave point. In that moment, when the loading was done, and the game made an autosave, HL2 exited, and dropped me back to the desktop, with no error message. What seems even more strange, is that if I don't move, while the save is being made, just wait and stand still for that few seconds - it doesn't exit. This is just pissing me off, and I never had an error like this on my desktop machine.
So, does anyone know, why this is happening?
