Desktop Graphics System: shorted board rail. A capacitor or semiconductor pulls a supply toward ground.

The distinguishing clue

Current draw is abnormal and protection may stop startup.

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: Isolate loads and locate the affected rail using controlled measurements. If confirmed: Replace the shorted component and verify resistance before power.

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

Related cause to rule out

When fans or lights start but the board never completes initialisation, also consider Desktop Graphics System: incorrect power sequence before choosing a repair.

Checks after the work

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