Understanding and Troubleshooting Post-Upgrade PC Power Issues: A Case Study
Transitioning between different hardware configurations can often introduce unforeseen technical challenges. Recently, a user shared their experience with persistent system startup issues following a significant hardware upgrade, highlighting the complexities involved in diagnosing such problems. This article aims to analyze that scenario, offering insights into potential causes and solutions for similar situations.
Background and System Specifications
The user’s original setup involved an Intel-based system, which was later upgraded to an AMD configuration. Here are the detailed specifications for both builds:
Intel-Based System:
- CPU: Intel Core i7-10700KF
- GPU: NVIDIA RTX 3060 Ti
- Motherboard: MSI MEG Z490i Unify
- Power Supply: PowerSpec 850W 80 Plus Gold
- RAM: 2 x 16GB T-Force Vulcan DDR4 at 3200MHz
AMD-Based System:
- CPU: AMD Ryzen 5 7600X3D
- GPU: NVIDIA RTX 3060 Ti
- Motherboard: ASUS B650-E TUF Gaming (AM5)
- Power Supply: PowerSpec 850W 80 Plus Gold
- RAM: 2 x 16GB G.Skill Flare X5 DDR5 at 6000MHz
Additional Context
The user notes a cautious approach to hardware modifications due to previous negative experiences and a reluctance to handle internal components themselves. Consequently, the local Microcenter has been the primary technician for hardware assembly and upgrades. Originally housed in a prebuilt NZXT H1 Mini case, the system was later transferred to a Fractal Torrent case to accommodate new components.
The upgrade process was initiated after noticing failing RAM modules, specifically used as an impetus to transition from DDR4 to DDR5 memory, alongside a motherboard and CPU upgrade.
The Core Issue
Shortly after completing the build with the AMD components, the system exhibited a peculiar startup behavior: pressing the power button initiates a brief power-up sequence, followed by an immediate shutdown — seemingly a failsafe response. Holding the power button results in the system repeatedly attempting to power on until the button is released.
Troubleshooting Attempts
The user brought the system back to Microcenter twice for professional diagnosis. During these visits, technicians tested the system on their bench, attempting to replicate the issue. Remarkably, during these test periods, the system operated flawlessly. Upon returning home, the system also ran without issues for
