Ike,

Please post your DXDIAG file (Not the MSInfo) so we can get more information about your computer.

Here's a support article that will show you how to get the DXDIAG:

Obtaining System Files

Once you have the DXDIAG file, open it and copy/paste the entire file into your next reply.

Ike,

Let's try uninstalling the current video driver and reinstalling an older video driver to see if that helps. To uninstall the current driver, you are going to want to use a program called Display Driver Uninstaller. This program will ensure that all previous driver files are completely removed.

Here's a link where the Display Driver Uninstaller program can be downloaded.

Once you have that downloaded and installed, try the following steps:

1. Run Display Driver Uninstaller.
2. You will be asked if you want to reboot into safe mode, click on "No".
3. Select "Nvidia" from the "Select Graphic Driver" drop down menu.
4. Click on the "Clean and restart" button.

After the system restarts, the video driver should be completely uninstalled so the graphics should look larger than usual. That's normal and it'll fix itself when the video driver is reinstalled.

Now that the driver is gone, we can go ahead with reinstalling it.

Here's a link for the driver download: Nvidia Driver

When you are going to install the driver I would like for you to select "Custom Install" > Uncheck everything except for the graphics driver > Check the "Perform a clean install" box > Continue with the install.

Ike,

The resolution could possibly be an issue. Are you running the game in windowed, full screen, or full screen windowed mode? What is your in-game resolution currently set to? Do you have the in-game Vsync option enabled or disabled?

If you are running in full screen mode, you might want to temporarily try running in windowed mode to see if that makes a difference.

Ike,

The black screens could be due to TDR errors. Here's an article from Nvidia with more information about those types of errors.

NVIDIA Statement on TDR Errors

If you look at the article you'll see that there is a lot of possible causes for this type of error. From what I've seen, the most effective solution is to underclock the video card a bit.

Let's get a little more detailed information about your video card.

Here's how:

1. Download and install the GPU-z program.
2. Launch GPU-Z and let it run for about 5 minutes before starting up the game.
3. Leave GPU-Z running and run the game for about 10 minutes.
4. Close the game.
5. Click on GPU-Z's "Graphics Card" tab.
6. Click on the Camera icon located on the top right corner.
7. Click on the "Upload to a free image hosting" button.
8. Copy and paste the first link into your next forum reply.
