Fixing Screen Glitches & Freezes During PC Gaming: Troubleshooting Guide

Screen artifacts (tearing, flickering, "going crazy") followed by system freezes are rarely caused by spyware. The culprit is almost always hardware or driver-related. Follow this diagnostic order.

1. Graphics Drivers (Most Likely)

• Clean-install latest GPU drivers (NVIDIA GeForce Experience / AMD Adrenalin). Use DDU (Display Driver Uninstaller) in Safe Mode first if updating over old versions.
• Roll back one version if the issue started after a recent update.

2. Overheating

• Monitor CPU/GPU temps with HWMonitor or MSI Afterburner while gaming. >90°C on GPU or >95°C on CPU indicates throttling/shutdown risk.
• Clean dust from heatsinks/fans; replace dried thermal paste (especially on laptops/older GPUs).
• Ensure case airflow: intake front/bottom, exhaust rear/top.

3. Insufficient Resources

• RAM: 8 GB is minimum for modern titles; 16 GB recommended. Check Task Manager → Performance → Memory for 95%+ usage.
• VRAM: Texture settings exceeding VRAM cause stuttering/texture pop-in. Lower "Texture Quality" in-game.
• Storage: Keep >15% free on OS drive (SSD preferred). Defragment HDDs.

4. Software Conflicts

• Disable overlays: Discord, Steam, GeForce Experience, Xbox Game Bar.
• Temporarily pause real-time antivirus (add game folder to exclusions instead).
• Close browsers, launchers, RGB software (iCUE, Armoury Crate) before playing.

5. Game-Specific Fixes

• Verify game files (Steam/Epic/GOG).
• Check PCGamingWiki for engine-specific fixes (e.g., ini edits for Unreal/Unity titles).
• Disable fullscreen optimizations (Right-click .exe → Properties → Compatibility).

6. Malware Check (Low Probability)

Run a full scan with Malwarebytes Free + Windows Defender Offline Scan. But prioritize steps 1–5 first.

If problems persist after all above, test the GPU in another system or borrow a known-good GPU to isolate hardware failure.
