Zorluk: OrtaMotherboard, RAM, CPU, and Power Issues

A field technician is troubleshooting a desktop workstation used for heavy video rendering. The system boots normally into the operating system and performs routine tasks fine. However, several minutes into a full GPU and CPU stress test, the workstation immediately powers off without displaying a crash screen or error code. Pressing the power button immediately after the shutdown yields no response, but waiting approximately 60 seconds allows the machine to power on and boot successfully again. Which of the following is the most likely root cause of this failure?

  1. The power supply unit is exceeding its rated wattage capacity under peak load, triggering internal overload protection circuit thermal reset.Cevap
  2. B
    The motherboard firmware is misinterpreting a runtime POST beep code and initiating an automated system power cut.
  3. C
    The system RAM was incorrectly populated using laptop SO-DIMM modules that desynchronize bus speeds under processing load.
  4. D
    The memory modules are installed across non-matching motherboard slots, disabling dual-channel mode and triggering hard thermal shutdowns.

Cevap

The power supply unit is exceeding its rated wattage capacity under peak load, triggering internal overload protection circuit thermal reset.
The correct answer identifies that when a power supply unit experiences demand exceeding its wattage rating under intensive processing loads, built-in protective features (such as Over-Power Protection or Over-Current Protection) trip to prevent physical component damage. This causes an instantaneous total loss of power and prevents immediate rebooting until the PSU protection circuits reset.

Adım Adım Çözüm

1
Analyze symptom pattern during system load
System instantly cuts power without OS error screens or blue screen crash dumps during high CPU/GPU stress.
Sudden hard power loss under heavy load points directly to power delivery failures or thermal safety triggers.
2
Evaluate behavior when trying to power back on immediately
The power button fails to respond right away but works after a 30 to 60-second delay.
This behavior indicates that PSU protective latches (such as Over-Power Protection) or thermal reset switches have tripped and require time to bleed residual energy before allowing restart.
3
Differentiate power supply tripping from motherboard/RAM memory failures
Confirm PSU wattage overload as the primary cause.
RAM errors cause operating system crashes (BSOD) or POST boot failures, whereas immediate power removal with a delayed button response is characteristic of PSU protection features.
