Issues with PC stability during games and occasional disconnections under load.
Issues with PC stability during games and occasional disconnections under load.
I've experienced these issues from the start of assembling my custom PC.
Components:
Motherboard: Asus Rog Strix Z490-F Gaming
CPU: i9-11900kf
GPU: GeForce RTX 3070 Ti
RAM: 16GB Trident Z DDR4
Power Supply: Thermaltake 850w TP 80+ Platinum
Storage: Samsung 980 Pro or similar, 512gb with 4tb average drive.
The problem is that occasionally I don't encounter crashes, but on other days I face several failures while gaming hardcore or experiencing crashes intermittently.
I brought it to a friend's PC shop recently and we tested the GPU; they replaced it with another powerful card. I assumed that was the cause then I changed the GPU slot position, which reduced crashes significantly... But I didn't test the other GPU for long, only checked the CPU and RAM.
Crash reports have been minimal—just random failures and brief Ethernet disconnections lasting seconds to a few minutes. The rest of the internet remained stable.
I've run extensive tests on the GPU, CPU, and RAM for hours without any crashes or errors. Recently, I suspected the BIOS might be the culprit. I searched for updates but found two years worth—still no improvement.
The issue persists: when it crashes, all three monitors flicker briefly before the PC shuts down and restarts. I strongly suspect the motherboard is responsible for these random Ethernet drops.
I've updated drivers regularly, checked for viruses and malware, even disabled anti-cheat and Windows security features. Still, I keep encountering error messages under Windows.
One thing is certain: my gut points to the motherboard as the likely source of these intermittent disconnections.
Could it be your PSU? Do you have access, even though it requires some effort to verify, to a PSU for troubleshooting?
