Your gaming PC is experiencing frequent crashes (Kernel Power 41 63).
Hi there, when i play games on my custom built computer sometimes the screen freezes, than it goes all black, i stop hearing sound and it needs to be rebooted. It's been happening for at least 1 year now and i don't really know what else to do. I've linked a screenshot from an app called BlueScreenView that analyzes minidumps and the fault seems to be dxgkrnl.sys called "DirectX Graphics Kernel" and nvlddmkm.sys. I tried a lot of stuff from the software side: i did a clean reinstall of my drivers with DDU multiple times, i tried to update my gpu's firmware, i tried testing my ram with both the integrated Windows tool and with MemTest86, i stressed both my CPU and GPU for a couple of hours without any crashing or thermal issues (both CPU and GPU were at the 70 degrees celsius range), i ran from the cmd the sfc /scannow command, the DISM, even the chdsk /f. I ran some anti-malware scans from both Microsoft Defender and Malwarebytes. I even fully reinstalled Windows 11, i'm with the Windows 11 Home 23H2 version. Neither my CPU nor GPU are overclocked, but my ram does have XMP on, but that can't be the cause because i tested the ram with MemTest and it didn't give me a single error. In the windows event viewer it says the error is Kernel-Power 41 (63) and it says that my system lost power unexpectedly. What should i do next? Here is the list of all my components: - GPU : GIGABYTE AORUS NVIDIA GeForce RTX 3060 Ti 8G Elite (REV 2.0) - CPU : Intel Core i7-10700KF - RAM : Corsair Vengeance Pro RGB 2x8 GB @ 3600 MHz (XMP ON) - CPU Cooling : Cooler Master MasterLiquid RGB V2 240mm AIO Liquid Cooler - Motherboard : MSI MPG Z490 GAMING PLUS - PSU : Corsair 750W 80+ white efficiency - OS Disk : i don't know the exact model, 256GB M.2 SATA. If it is an hardware issue, what component should i change?
I’d consider a stronger power supply unit. That’s essentially what the failure indicates.
Well, some websites suggest a 600-watt unit should suffice and 750 is excessive... but keep in mind, power supply units can degrade over time, which might affect your setup. Generally, you get what you pay for—cheap PSUs often don’t match the performance of higher-end models unless they’re discounted. I’d prefer an 850-watt PSU with a hassle-free return policy. Make sure to disconnect all old cables and only use the ones that came with the new unit when testing.
You might explore additional software options or troubleshooting steps to address the issue further.
You can use windbg to load your bluescreen dump file, or if you're unsure about the contents, simply upload it and a specialist will likely examine it for you.
