The program requires a shutdown to complete properly.
Hey everyone! I'm facing some challenges with my new setup. I've assembled everything from scratch using the most dependable parts available locally, and even without tweaking the BIOS, Cinebench isn't working properly. I'm not particularly experienced in PC building, so I'm running out of ideas. Could you please share as much detail as possible? I'll do my best to clarify the situation right away.
My system includes:
- Case: Cooler Master MCM-SL600M-KGNN-S00
- Motherboard: ROG STRIX X670E-E Gaming WiFi BIOS 1602 (default profile, no changes)
- CPU: Ryzen 9 7950X3D
- Cooler: NZXT Kraken Elite 280
- Display: 280mm LCD, black, RL-KN28E-B1 RAM Trident Z5 Neo RGB DDR5-6000 CL30-40-96 (1.40V)
- GPU: AMD Radeon RTX 3080 Ti with 12GB GDDR6X VRAM
- Storage: PCIe NVMe SSD PNY CS3140, 8TB M.2 2280
- Power: ROG THOR 1000W Platinum II, RGB, full modular, 80 Plus Platinum
- OS: Latest Windows 11, running the newest version
- Performance: 12G-P5-3967-RX, stable under load
I've tried various fixes—even adjusting the CPU speed—but nothing seems to help. The issue mainly shows up during multi-threaded tasks, long runs (like 10 or 30 minutes), or stability tests. It just shuts down automatically, except for single-threaded sessions. I haven't found much useful info online, so I'll focus on what's happening now.
Also, the problem seems to appear when playing games, especially Battlefield 2042. I'm based in Brazil, so local support might be limited. If I need to contact a warranty service, it could take months.
Thanks for your help!
Review the Windows Event Log for any recent entries. It could hold a hint in the system logs.
I faced a comparable problem with my test bench a couple of months ago; it became clear that my PSU was nearing failure (RIP AX1200i). This situation is also mentioned for the B650E Master from Gigabyte, where under intense multithreaded AVX tasks the system unexpectedly shuts down. While I haven’t seen similar reports on your board, this issue seems unlikely to stem from software—more likely you’ll need to pursue a warranty repair for a component. The main concern now is identifying which part requires replacement. Do you have any spare parts available for testing, such as an old PSU? That would be the most probable option, though I can’t confirm it without being directly involved.
Yes, I have another power supply unit. I'll follow up soon. All components are brand new. I'm wondering if bent pins on the motherboard might be the issue—I didn't notice them during setup but saw some when installing the CPU... Not sure. I'm running a memory test with Windows and hoping it's the PSU. If that's the case, I can return it without too many problems.
I've linked a second power supply to the motherboard with 2x8-pin CPU and 12-pin MB cables. The damaged PSU remains connected to the AIO and a few SSDs, while the GPU stays unplugged. I used a jumper to power the PSU connected to the AIO. The computer starts up normally. Cinebench still triggers shutdowns. Memory tests completed without issues. The riser cable is still attached to the GPU, but I'm unsure. I'm curious if these memory tests could reveal CPU problems. Before troubleshooting, I was using a Carbonaut thermal pad and assumed overheating was the cause. After removing it, applying standard thermal paste and reattaching the AIO, I found it highly unlikely I applied pressure incorrectly during the second CPU install.
Alright, I just took out the riser and it seems like it helped. The system can now run Cinebench for a longer time. It hasn’t hit the 30-minute target yet, but I’ve reached 25 minutes so far.
It seems strange since the issue might be linked to the riser. If it were the cause, it would have resolved it; otherwise, nothing would have changed. I’d start suspecting the motherboard is faulty, though we can’t confirm without a replacement to test.
Great update, I believe I fixed the problem. The PCIe behavior was odd, so my last attempt was to reset the CPU. I removed the AIO and the thermal guard, cleaned the CPU thoroughly, and applied a fresh thermal paste from Thermal Grizzly. After reassembling everything, the Cinebench test ran smoothly with stable temperatures and no issues. It seems the CPU guard might have been the main culprit, possibly affecting pressure between components. I’m confident the fix worked. The main challenge was dealing with the mounting pressure during installation, which I overcame thanks to your guidance. Appreciate all the help!
