What is using my CPU???
So I got this laptop around a month ago, brand new, the Dell Vostro 3405 with the AMD Ryzen 3450u and when I'm gaming or doing whatever I see like 80% usage spikes but then I look at the actual processes or tasks or whatever that are active and there is like a couple things only that are using say, 20% CPU and, nothing else, like 2 or 3 things besides that that are using like 3% CPU each. Its so annoying because when I'm doing whatever, playing 1080p youtube, gaming, etc, it slows down when I try to like close a program, load a new page (its not a bigg slow down but its just not smooth) so I don't know why there are CPU usage spikes like that but it doesn't really show what is pushing the CPU to 100% usage each time on task manager. Also, some times it just runs fine, 60FPS stable while gaming (I know this machine is capable of more even, we're talking League of Legends, that the game I play most of the time) but then some times I just get low, unstable FPS, like around 30 and going even below that in moments of high action on screen (graphics set to low, vsync etc disabled). I don't know what's happening, maybe something's causing the CPU/GPU to throttle, something is causing the CPU to get to 100% usage when it shouldn't do that, but something is causing the PC to slow down. The laptop came with Windows 10 LTSC (installed by the local store that sold it to me) and I recently installed Windows 11 Pro (which Dell says this machine is compatible with). Something else to mention, I don't think this PC thermal throttles (maybe, I don't know what the threshold is for this specific machine) but it stabilizes at around 70 degrees under heavy load and it maintains that) Hope you guys can help me figure out what is causing my PC to have CPU usage spikes when stuff are loading (when chrome pages loading, game client pages loading, booting up game client(LoL cliente), etc, and why some times I get low frame rates when this machine should be capable of running League of Legends at least at a steady 60FPS no problem. If you need any extra info to try to help me I'll gladly provide, thank you in advance
Click the right button and select "Open file location" to see the exact path it's accessing.
This behavior seems typical under normal conditions. Expect some CPU activity when loading, particularly in games where disk operations and asset compression consume significant resources. Laptops often have power settings that reduce performance after a certain time, which can cause throttling. I noticed my 2500U worked well for about ten minutes before dropping to 30fps due to frame rate limits. There was no option to prevent this, and it likely stemmed from the laptop’s design to conserve power rather than delivering sustained high performance.
It's strange how it reacts even with constant power. This device uses an NVMe SSD for main storage, and I'm not entirely sure if people refer to NVMe drives as SSDs too.
I haven't seen anything unusual, just some occasional high CPU activity. When you check the process list, there aren't any processes consuming excessive resources. I don’t think malware is involved, but I’m not entirely sure. The only applications that use the most CPU are the game and the browser.
