One of your CPU cores wasn't using any resources at all!
Hey! This definitely doesn’t seem normal. I didn’t alter any BIOS settings or tweak my PC configuration. Suddenly, one of my CPU cores stopped working. Is it time for the processor to give up? At first, I thought it was because a game wasn’t using that core well, but when I tried to use it for rendering in Resolve, it still didn’t show any activity. It’s the same with Cinebench. I’ve updated the BIOS to the latest supported version, used Unpark software, and set Windows power management to High Performance, but nothing helped. Now, this core only works for a few seconds before the system goes into sleep mode. Anyone have any ideas on how to fix this? It feels like my CPU is giving up completely. My specs are: Ryzen 5 1500X, 16GB DDR4 @2667MT/s, Sapphire RX570 4GB, Colorful A320M-K PRO V14, Adata SU650 512GB for boot, Cooler Master MWE450 (version unknown), and Windows 10 22H2 Build 19045.5247. After restarting, I run Cinebench and it still doesn’t respond.
The CPU isn't necessarily failing despite the utilization graph. A dead core appears as 0% usage, and since it's a quad-core processor, only one thread shows low activity while the others run at full capacity. It's unclear what to fix, but a possible cause could be the Windows scheduler or a corrupted file from an update. Testing with a Linux live USB to run a CPU benchmark might clarify whether the issue lies in BIOS/hardware or software.
You're correct... my windows is putting a strain on the processor. I've checked CPU benchmarking on Linux Mint and all cores are being used. I'm hoping I don't have to reinstall windows. empowered
Make sure your CPU is functioning properly before updating Windows. Look for the most recent updates and see if any CPU, scheduling, or related issues are addressed. If problems persist, consider reverting those updates to see if it restores performance. Otherwise, a fresh installation might be the best option. Windows tends to lose efficiency over time, so starting over could be the solution.
I've attempted to update Windows using the scan and DISM tools, but one core remains inactive. It seems reinstalling might be necessary since I can't revert changes. Thanks for your help!
I face the same issue. If the program was limited to run in thread 2 (cpu core 1 in Task Manager), that thread could use full capacity. I believe it's a Windows 10 thread scheduler problem.
