Graphics Driver Diagnostic Checklist:

Check If Driver Is Installed:
1. Open Device Manager (Win+R → devmgmt.msc)
2. Expand "Display adapters"
3. Look for your GPU (NVIDIA/AMD/Intel)
4. If you see a question mark (?) = Driver missing
5. If no question mark = Driver is installed

View Driver Details:
1. Device Manager → Display adapters
2. Right-click your GPU → Properties
3. Switch to "Driver" tab
4. Check:
   - Driver Version (for research online)
   - Driver Date (when it was released)
   - Device Status (should say "working properly")

1. Press Win+R and type: dxdiag
2. Click "Display" tab
3. You'll see:
   - GPU name and memory

4. Note these details for troubleshooting

Diagnose Graphics Performance Issues:
1. Open Task Manager (Ctrl+Shift+Esc)
2. Go to Performance tab
3. Click on GPU in the left sidebar

5. If GPU usage is stuck at high % during idle:
   - Driver might need update
   - Background app using GPU
