I have a mercury motherboard with NVIDIA chipset(GeForce 7050),with a 1 GB RAM.My internal video memory is 512 MB.In fact I only bought the whole thing just a couple of days ago.My problem is that,I installed NFS Carbon in my computer.It all went well and when I finished playing for the day and shut my computer I cannot start it again the next day.The windows logo loads and after that I can only see a black screen and it freezes like that.I must again restore the system in the safe mode to the point before the installation of the game to get things to normal.Why is this happening?I think 512MB graphic memory is more than enough for the game(It requires only 64 MB).What is the problem?Please help me.
