Desktop Graphics System: heat-sensitive board component. Cooling, solder fatigue or internal degradation makes a board component unstable under load.

The distinguishing clue

Crashes appear at a repeatable temperature or workload.

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: Log temperature, clock and power while testing cooling first. If confirmed: Repair cooling or replace the confirmed damaged component.

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

Related cause to rule out

When the computer works at light load but becomes unstable as demand changes, also consider Desktop Graphics Problems: Check the Output, Power and Card Separately before choosing a repair.

Checks after the work

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