Windows 7 Blue Dots on Monitor

[Mach10]

I am having a problem with 10's to 100's of blue dots on my screen. I can place a video feed or another computer on the monitor with no blue pixels. Additionally, the screen gets "fuzzy" in places. It is in spots, not a line completely accross the screen. It get worse at time and better at others. I can't seem to track why. Any thoughts would be appreciated. I assume it is due drivers not being mature, but I don't know.

I can reduce the issue by removing SLI, but it still exists. The reason I have two video cards is to run them in SLI. I love gaming and video editing for fun. I really want to be able to use the 64-bit version to allow it to recognize more ram.

The issue you are experiencing with blue dots on your screen accompanied by occasional fuzziness can be concerning, especially when it affects your gaming and video editing experiences. Let's break down some possible reasons for these display abnormalities:

Possible Causes and Solutions:​

1. Driver Issues:
   • Graphics Driver: The symptoms you described might be related to graphics driver issues. The graphics driver version 185.81 you mentioned is quite old, and updating to the latest driver might help resolve these display problems. You can check NVIDIA's official website for the most recent drivers for your 8800 GT GPUs.
   []SLI Configuration:
   • SLI Compatibility: SLI configurations can sometimes introduce display anomalies. Try running your system with only one 8800 GT card to see if the blue dots and fuzziness persist. If the issue resolves with a single card, it could be related to the SLI setup or a specific card causing the problem.
   []Hardware Troubleshooting:
   • Monitor Connection: Ensure that the connections between your monitor and graphics card are secure. Try using different cables or ports to rule out any issues with the physical connection.
   • Monitor Test: As you mentioned, when you input a video feed or another computer to the monitor, there are no blue dots. This suggests that the monitor itself is likely not the problem.
2. System Environment:
   • System Cooling: Ensure that your system is adequately cooled. Overheating can sometimes cause graphical issues, particularly in demanding applications like gaming and video editing.

System Information Review:​

• Operating System: Microsoft Windows 7 Ultimate (Build 7100)
• Processor: Intel Core 2 Duo E6850 @ 3.00GHz
• Graphics Cards: 2x NVIDIA 8800 GT running in SLI
• Motherboard Driver: nForce 680i SLI - Version 15.35
• Graphics Driver: Version 185.81
• RAM: 4.00 GB (Total Physical Memory)
• Monitor: Gateway LP2407 (1920x1200 resolution)

Recommendations:​

1. Driver Update: Install the latest graphics drivers compatible with your system.
2. SLI Configuration Check: Test the system with a single GPU to isolate potential SLI-related issues.
3. Monitoring: Keep an eye on the system's temperature to ensure it's within safe limits.

By addressing these points, you can troubleshoot the blue dots and screen fuzziness on your system. If the issue persists after these steps, further investigation into the hardware components or advanced troubleshooting may be required.
