Hi everyone,
I'm looking for people who may have experienced a similar issue with their laptop, especially owners of the same model, and who might have identified the actual root cause.
Laptop: Acer Nitro V 15 ANV15-52-57BB
GPU: NVIDIA GeForce RTX 5050 Laptop GPU
Wi-Fi adapter: MediaTek Wi-Fi 6 MT7920
Ethernet adapter: Killer E2600 Gigabit Ethernet Controller
I bought this laptop in early June 2026, and I've been experiencing complete system freezes while gaming and occasionally when watching YouTube videos after gaming.
When the issue occurs, the entire laptop becomes completely unresponsive. The screen freezes, and I cannot recover the system normally. The only way to get it working again is to force a shutdown by holding down the power button.
What I've tried so far
We've spent quite a bit of time troubleshooting the issue and investigating possible causes:
- Tested the GPU and RAM for potential hardware issues.
- Updated the graphics drivers.
- Performed clean driver installations.
- Updated the BIOS.
- Updated the VBIOS.
- Investigated potential graphics-related and system stability issues.
Despite all these tests and updates, the problem persisted.
The breakthrough: disabling Wi-Fi stops the freezes
Eventually, we discovered something unexpected: the freezes seem to occur only when Wi-Fi is enabled.
After disabling Wi-Fi, the laptop stopped freezing. I'm currently using a wired Ethernet connection as a workaround, and the system has remained stable with Wi-Fi disabled.
This finding significantly changed the direction of the investigation. Since the issue disappears when Wi-Fi is disabled, I'm wondering whether it could be related to the MediaTek wireless adapter's driver, power management, a Windows or networking issue, or possibly a hardware fault.
However, we haven't identified the definitive cause, so I don't want to assume it's a software or hardware problem without further evidence.
Has anyone experienced this, particularly on an Acer Nitro V 15?
I'd especially appreciate hearing from owners of the Acer Nitro V 15 ANV15-52-57BB, but experiences with other laptops using the MediaTek MT7920 Wi-Fi adapter would also be helpful.
- Have you experienced complete system freezes while gaming that stopped when Wi-Fi was disabled?
- Did you eventually identify the actual root cause?
- Was it a driver or software issue, a compatibility problem, or a faulty Wi-Fi adapter?
- If you found a definitive solution, what exactly fixed it?
- Has anyone had this issue diagnosed or resolved through Acer warranty service?
I'm not looking to start another round of generic troubleshooting at the moment. I'm mainly interested in hearing from people who experienced the same symptoms and, ideally, discovered what was actually causing them.
The laptop is still under warranty, so I'll consider taking it in for service if the issue remains unresolved. For now, Ethernet is a workable temporary solution, but I'd like to understand what's happening before deciding on the next step.
Thanks in advance to anyone who can share their experience or point me toward a confirmed root cause.
