The computer stops working properly during gaming sessions.
Greetings,
I purchased my computer three years ago, and it performed well until approximately one to two weeks ago when it began unexpectedly shutting down during video game play (typically after 10-30 minutes). Initially, I suspected that the intense heat wave in my region might be a factor; however, monitoring my GPU and CPU temperatures before these crashes revealed normal readings – the CPU reached 50-60°C, and the GPU stayed between 65-72°C using monitoring tools like HWMonitor and CoreTemp. Despite these normal temperatures, the shutdowns persisted. Removing all case fans temporarily improved performance for 3-4 hours, but the problem swiftly returned, even when I left one side of the case open completely. Notably, the GPU consistently runs hot along its circuit board while remaining relatively cool on the side with the fans. Consequently, I am thoroughly perplexed and uncertain about the root cause, having considered a potential problem with my power supply unit (PSU), though it has functioned without issues for the past two to three years.
Here are my system details:
Windows 10 Home
Motherboard: Gigabyte AORUS GA-Z270X-Gaming K5
GPU: NVIDIA Geforce GTX 1070
CPU: Intel Core i7 7700k (4.2GHz)
Cooler: Cooler Master MasterLiquid 120 Pro
PSU: EVGA SUPERNOVA 650P2 (80 PLUS PLATINUM, 650W)
RAM: DDR4 16GB 1200MHz
HDD: WDC WD20EZRZ 2TB
SSD: Crucial CT275 MX300 275GB
Monitor system voltages with HWMonitor, then execute the Heaven benchmark. If your voltage readings exhibit excessive fluctuation (exceeding a 5% margin), the problem likely lies with your power supply unit.

Using Heaven benchmark, I observed that the most fluctuating voltages were on the CPU Voltage Input Delivery (VID) – specifically VID#0 through VID#4, shifting between approximately 1.120V and 1.180V, occasionally dipping to 0.900V. Interestingly, these variations continued even when the computer was inactive, ranging from 0.760V to 0.900V. Other voltage readings appeared relatively consistent, with minor shifts on the motherboard side but not substantial changes overall.
To definitively determine the issue, repeat testing with your original power supply and conduct several tests utilizing a reliable power source. If the problem persists when using your current PSU, but consistently resolves with a known-good supply, then you’ve identified the source of the problem: your power supply.
