Did Windows 11 just get super slow without any reason?
Did Windows 11 just get super slow without any reason?
Hello everyone, I have an Intel i9 9900ks plus an RTX 3090 and 32GB of RAM. My computer worked fine yesterday, but today it acts very slow. Even moving my mouse is sluggish and laggy. It takes about two seconds to open menus when right-clicking, opening a program takes two to five seconds. Everything feels stuck and I don't know if I did something wrong. Any idea why this happened? I tried updating Windows to the latest version (it's automatic and everything looks up-to-date) and removing some programs known to cause problems like antivirus and Razer Synapse. The Nvidia driver is current. When I checked my tasks, the CPU uses only about 10% and memory uses 25%, while Firefox seems to be using the most resources. I couldn't see any program eating too much power or resources. I booted my PC in safe mode and the problem disappeared (so it's likely a software issue, not hardware). I checked for viruses with Avast free antivirus and found nothing. I didn't change any settings. This computer was working fine before everything went wrong. One of my hard drives is full; maybe that caused it? (The drive is full of media files but not the operating system, which is on a separate SSD.) Also, last night while my PC was running, we lost power and wondered if that might be related to this problem.

Try the built-in Windows troubleshooting steps right away. They might find and fix something. If that doesn't work, open Task Manager, Resource Monitor, and Process Explorer (free from Microsoft) to see how your computer is doing. Use all three tools, but only one at a time. Watch for a few minutes then move your mouse around to notice what happens when things get slow or laggy. The goal is to figure out which system resources are being used, how much (%), and who is using them. Check the little arrows in the column headers because clicking them will let you sort things and spot problems easier. If Process Explorer shows up, use it to find processes that don't look right; search online if needed. https://learn.microsoft.com/en-us/sysint...s-explorer This tool can take some trial and error, so be patient and careful. Power loss might have messed up some files. Try reinstalling drivers if your mouse acts weird. Run "sfc /scannow" and the DISM command to fix system files. https://www.lifewire.com/how-to-use-sfc-...es-2626161 Then use the DISM tool to repair your Windows 10 image after seeing what you find.
The CPU usage never goes higher than 18%. Most of the time it sits idle at less than 10%. The Windows troubleshooter didn't help much. The sfc scan found broken files and fixed them, but that did not fix the problem. A few programs like "windows shell experience host" are stopped in Resource Monitor, but I don't think that is a big deal. One thing that made me suspicious was the I/O seen in Process Explorer; it jumps around at regular intervals. It can be as low as just a few kilobytes and jump up to 300 megabytes range. Is that something to worry about? Also, another small detail I noticed is when I restart my PC, for the first few seconds it's fast then it gets slow. That makes me think maybe the issue is software related.
I'm not sure what's wrong with the I/O settings in Process Explorer. Maybe I need more info right now. Or you could take a picture of the screen and send it over here on imgur.com. If your PC gets fast for a split second but then slows down, check Task Scheduler instead. Something might be starting up all by itself. Look at Task Manager > Startup tab too. It could be an app or program trying to run, update something, make a backup file, or just "phone home" on its own.
