Desktop Graphics System: open circuit or connection. A pin, trace, socket or component no longer carries its required signal.

The distinguishing clue

One rail or channel is absent while neighbouring stages work.

Checks before an assessment

Record which output is connected and whether the CPU has supported integrated graphics. A motherboard display socket alone does not prove that it can drive the monitor.

Stop point: Stop load testing if artefacts combine with excessive heat or electrical smell.

Workshop confirmation and repair

Device-level check: Compare outputs, cables, card power, temperature and a known graphics path.

Targeted check: Trace continuity and signal progression with power isolated where required. If confirmed: Repair the open path and its mechanical or thermal cause.

Repair boundary: Repair the connector, cooling, power or confirmed graphics hardware.

Related cause to rule out

When the fault changes with temperature or chassis flex, also consider Desktop Graphics System: intermittent solder joint before choosing a repair.

Checks after the work

After repair or replacement, check all outputs, video, graphics load, temperature and cold starts.
