First, please post the REQUIRED information from the PINNED Troubleshooting topic, as You left out A LOT of information that is helpful in determining a solution to your problem, and they are:
What is your Processor?
What is the Processor Speed?
What is the Video card?
What is the Total Vram?
What is the Dedicated vram?
Do you have the latest SP for the OS?
Is this the Retail(DVD) version OR a Downloaded version?
If Downloaded, from where?
If Retail, Is this the Original DVD being used OR a No-DVD crack OR A Copy of said DVD being used?
Is this V1, V2, OR V3 game?
Any Daemon tools or the like installed on PC?-These can cause problems with games..
**To find above info, go to Start, Run(if XP)/Search(If Vista, 7, or 8) and type in DXDIAG and press Enter, the first page is the OS, Ram, Processor information and the Display tab is the Video card information
How can we help you, IF you do not post your system specs and stuff?..Please be more specific in your topics in the future. Thanks
