Hello there, my name is Dilan. I’m from Italy and came here because Reddit didn’t help much. I often watch Linus’ videos and found this forum he made. I’m trying to figure out what’s happening with my computer. Here’s a quick rundown of my setup:
Processor: Ryzen 9 5900X
Graphics Card: RX 6750 XT
Motherboard: Mag B550 Tomahawk
RAM: Corsair Vengeance LPX DDR4 32GB (two 16GB sticks)
Storage: W.D. Black NVMe SSD 1TB
Power Supply: Corsair CX650 650W
I’ll record a short video of what’s going on.
Two weeks ago, I assembled this PC and just installed Windows 11 with lots of games—War Thunder, Fortnite, LoL, Battlefield 5, Valorant. The next day, it crashed three times: first two without any error, the third with a blue screen. Checking Event Viewer showed a Kernel Power 41 warning often. I tried everything—reinstalling OS, drivers, disabling XMP, updating chipset and BIOS. I didn’t overclock anything.
I ran stress tests: Memtest86 on RAM passed, AIDA64 on CPU, RAM, board, storage all good with normal temps. Prime95 for CPU and CPU/RAM also showed no issues. Adrenalin software for the GPU gave perfect temps and no problems.
Someone suggested it might be a faulty part, but since this was my first build, I couldn’t swap components to test. The main clues were:
- PSU had overcurrent protection on the GPU during a voltage spike.
- CPU memory controller might be damaged.
- The motherboard could have a fuse blown.
I only got RAM that’s Crucial Pro DDR4 32GB CP2K16G4DFRA32A, which still crashed after a few games.
Last week, I handed it over to a technician because I didn’t have replacement parts. He said wait a week. Two days later, I got it back. The guy checked everything and said all parts were fine—possibly a driver issue. He did a GPU driver DDU test and told me if it crashed again, I’d have to go back to Windows 23H2 because the 24H2 had problems. That day nothing happened, and I played without issues. The next day, again—Fortnite and War Thunder crashed.
Today, I had another crash in Fortnite, so I reverted to 23H2 and reinstalled everything. Still, it crashed in both games.
I’m confused: if it’s a hardware problem, why didn’t it fail every time I tested? I noticed crashes only in War Thunder, Fortnite, and once in Valorant (due to Vanguard). I thought maybe each game has its own anti-cheat or something. I tried Chivarly 2 tonight, which is CPU-heavy, and it worked.
Questions that keep coming up:
- If it’s a hardware issue, why didn’t it fail in every test I ran?
- Did the PSU overcurrent protect the GPU during voltage spikes?
- Was the CPU memory controller damaged?
- Could the motherboard be faulty?
- Why did RAM pass all tests without errors?
I’m not sure what to do next. Please explain things simply, like you’re five years old. I’m new here and really need help.
Feel free to ask if you have more questions!
Currently I struggle with anything under 750, but I believe a 650 isn't too much of an issue here—it's likely the hardware is faulty. You should reach out to Corsair's support for assistance. If the problem is resolved within 30 days, they may advise returning it to the retailer for a replacement. For future purchases, aim for at least B tier on this list: https://cultists.network/140/psu-tier-list/
Focus on the key features: Atx 3.0 offers advanced control options. Multi/single-rail switchable lets you toggle between multiple or just one rail. Multi-rail only restricts operation to specific rails, while single-rail only limits it to a single rail. These settings help optimize performance and compatibility in your setup.
The dump indicates a CPU hardware issue. It doesn't specify the exact location, so you must analyze the RawData in the Advanced tab. If you receive data after shutdowns, it's likely BERT rather than a Machine Check Exception—Windows may group BERT into the same event. There’s no official guide for BERT. Since it occurred during a shutdown and lacks documentation, we can only confirm "CPU or a PCIe device." Based on the file context, CPU is the probable cause. If you need assistance, right-click → save on the event and share it in the same format as the dump.
