Why is my laptop glitching
A laptop that is "glitching" — the image tears, blocks of the screen repeat, colours flash, windows smear — is the graphics chip or its driver far more often than the screen.

Screenshot and external monitor: glitch on both = graphics. Lid tilt: changes = cable. Check the temperature — a cool machine that glitches when hot is the GPU.
What it is
A laptop that is "glitching" — the image tears, blocks of the screen repeat, colours flash, windows smear — is the graphics chip or its driver far more often than the screen. Artefacts that also show in a screenshot or on an external monitor are graphics. Flicker or flashing that changes with the lid angle is the display cable. A screen that corrupts only when the laptop is hot is a failing graphics chip.
Can it be fixed?
Driver: yes — clean reinstall. Cable: small repair. Failing GPU: a motherboard, and that decides whether the laptop is worth it.
What to do
- Clean graphics driver reinstall.
- Screenshot + external monitor.
- Clean the fans; check temperatures.
- Lid-angle changes: cable repair.

Warranty
Most makers replace a panel under warranty for physical panel faults that are not accidental damage; pressure marks, cracks and liquid damage are treated as accidental and are not covered. For dead pixels, each brand has a threshold (typically 3–5 bright or 5–8 dark pixels on a laptop; Dell's premium-panel guarantee replaces at one bright pixel).
