Laptop display issue is from the Taskbar like Flickering screen














Your issue with the HP ProBook 650 G8 — where the taskbar blinks and lines appear on the screen, but goes away after a reboot and returns again after 5–10 minutes — is likely display-related, and could be caused by:

🔍 Possible Causes

1. Faulty or Incompatible Display Driver

  • Outdated or buggy Intel/AMD graphics drivers

  • Windows may auto-install older versions after reboot

2. Windows Explorer Crash/Loop

  • Taskbar blinking may be due to explorer.exe crashing or restarting

3. Hardware Fault (Display Cable or Screen)

  • If the issue appears even in BIOS or Safe Mode, it might be a loose display cable or LCD panel issue

4. Malware or Background Conflict

  • Sometimes, background apps or malware cause explorer or display loops

✅ Step-by-Step Fixes

✅ 1. Update Display Drivers

  1. Press Win + X > Device Manager

  2. Expand Display adapters

  3. Right-click Intel/AMD graphics > Update driver

  4. Select Search automatically

👉 Or download directly from HP:
🔗 HP Drivers for ProBook 650 G8

✅ 2. Disable Hardware Acceleration (Temporary Fix)

  1. Open Settings > System > Display

  2. Click Graphics Settings (bottom)

  3. Enable "Hardware-accelerated GPU scheduling" OFF (if ON)

  4. Restart

✅ 3. Run SFC & DISM (System Repair)

Open Command Prompt as Administrator and run:

bash
sfc /scannow
DISM /Online /Cleanup-Image /RestoreHealth

This checks and repairs any system file corruption.

✅ 4. Check in Safe Mode

  1. Restart and press F8 or hold Shift + Restart

  2. Choose Startup Settings > Safe Mode

👉 If the issue doesn't happen in Safe Mode = likely driver or software issue
👉 If it still happens = possible hardware issue

✅ 5. Check for Malware

Run a full scan using:

  • Windows Defender

  • Or Malwarebytes (free version)

✅ 6. BIOS Update (if all else fails)

  1. Visit HP's official support page

  2. Download latest BIOS for your model

  3. Follow instructions carefully

🛠 Hardware Check (Optional)

If all software fixes fail:

  • Connect the laptop to external monitor

    • If no blinking or lines = issue with laptop screen/cable

    • If same issue = likely GPU or software
