Hi Leif McGuire,
Thanks for reaching out here in the Microsoft Q&A. I can understand the inconvenience this issue has caused you. To help resolve this issue, please follow the steps outlined below:
Step 1: Check if the Issue is Hardware or Software
1 - Boot into BIOS/UEFI (Restart > Spam Del/F2/F12):
- If dots appear in BIOS > Hardware issue (GPU, display, or cable).
- If dots only appear in Windows > Software/driver conflict persists.
2 - Test with a Live Linux USB:
- If dots don’t appear in Linux > Windows/driver problem.
- If dots persist in Linux > GPU or monitor is failing.
Step 2: Rule Out GPU Failure
1 - Stress Test the GPU:
- Use a GPU stress-testing tool to load the graphics card.
- If dots increase or screen crashes > GPU is defective.
2 - Monitor GPU Temperatures:
- Use a system monitoring tool to check GPU temperatures and performance.
- If temps exceed 85–90°C > clean fans/reapply thermal paste.
3 - Try Another GPU: Swap in a different GPU—if dots vanish, your original GPU is faulty.
Step 3: Test the Display Panel/Monitor
- Try a different monitor and replace HDMI/DP cable.
- Test another port (e.g., switch from HDMI to DisplayPort).
Step 4: Disable Hardware Acceleration in Apps
Reduces GPU load in apps like Discord, where the dots are noticeable, addressing potential app-specific conflicts This is quick and targets software issues.
- In Discord: Open Discord > User Settings (gear icon) > Appearance > Toggle off Hardware Acceleration > Restart.
- In Browsers (if used): Go to Settings > System > Turn off Use hardware acceleration when available > Restart browser.
- Test on a dark background.
Step 5: Reinstall Graphics Drivers
Addresses driver mismatches or corruption, especially since your prior driver attempt failed due to a model mismatch. A clean install ensures no residual driver issues.
1 - Identify GPU: Right-click Start > Device Manager > Expand Display adapters to note your GPU.
2 - Download Driver:
- Visit and download the drivers from their official sites.
- Select your GPU model and Windows 10 (64-bit or 32-bit).
3 - Boot into Safe Mode: Press Windows + R > Type msconfig > Boot tab > Check Safe boot (Minimal) > Restart.
4 - Use DDU:
- Download DDU.
- Run DDU in Safe Mode, select your GPU > Clean and restart.
5 - Install Driver: After reboot, install the downloaded driver > Restart again.

Step 6: Test in Safe Mode
Determines if the issue is software-related (e.g., drivers, apps) or hardware-related (e.g., monitor, pixels) by loading minimal drivers and services. This guides next steps.
- Press Windows + R > Type msconfig > Boot tab > Check Safe boot (Minimal) > Restart.
- In Safe Mode, open a dark image or Discord to check for blue dots.
- Exit Safe Mode: Run msconfig again > uncheck Safe boot > restart.
