I"m relatively new to self-hosting and I have an instance on Oracle cloud with a few apps that I run. More recently this instance is becoming unresponsive every 30 minutes or so. It becomes impossible to SSH to it and any connection to it is dropped. Oracle Cloud says that it is unresponsive, forcibly rebooting it fixes the issue until it becomes unresponsive again in 30 minutes. I believe the most major thing I did since this started was installing Java and doing an "apt update" followed by "apt upgrade" after many months of not doing it. I have tried to turn off every service that I have running using pm2 and systemctl. No luck. Are there any tools that I can use to better understand why it is freezing like that?

Edit: I ran the following command systemctl --type=service --state=running And noticed there was a Gnome Display Manager that was running and I wasn't using it. After disabling this service with systemctl disable [servicename] The server stopped crashing. Thanks for all the replies!

As you can see on the screenshot. Task Manager is saying that the Active Time of my NVM.e system drive has a lot of peaks that start to happen after a few minutes of using the PC and they won't go away unless I restart. I have tried so many things that I gave up and formatted the whole drive and reinstalled Windows from scratch. I have also tried the chkdsk command and this problem won't go away. This started to happen just a few days ago, out of the blue. The whole system freezes at every peak you see on the screenshot and the main tab of Task Manager reports the Disk Usage as being ~1%, so there is no process using the disk. Resource Monitor is also reporting the same thing.

Edit: I have narrowed down the problem to a insanely high Response Time on Resource Monitor (up to 2000ms). It is usually the “System” process that is having this high Response Time. Any way of fixing or at least knowing the root cause of this?

I have a JBL Quantum 300 that has a boom flip up microphone that is extremely quiet so I have to preamp it by 20db to make my voice be heard. The problem is, when I do this the sound of the headphone can be clearly heard on the microphone. I have tried several different drivers, tried both the front panel and the back panel, multiple Windows installations, both 10 and 11 and multiple BIOS updates as well. The sound can also be heard if the microphone is flipped up (muted). The result is every time I'm in a call with someone, they can clearly hear everything on the computer even their own voices being played on my headphone. How can I mitigate this? I have EqAPO installed, is there any plugin/feature that can do Echo Cancellation?

My motherboard is an MSI Z370A-PRO

I selfhosted my Nextcloud and really enjoyed it for personal use. One of my friends took a look into it and thought that it could be a good thing for his company that employees +200 people and growing... They are currently using Google Workspace but want to ditch it completely in favor of something that they can control themselves. So here's my question, is it worth to use NextCloud on a company of this size, is there a better alternative? Or should they just keep using Megacorporation's cloud solutions? If it is worth it, how much should I charge them for hosting it and doing the implementation and support?

I've bought an used RX 5600 XT that is arriving this week, this is my first AMD GPU so I'm wondering if there is any setting or app that every AMD user should use. I've heard of "resizeable bar" before but I have no ideia what it is and if I should even mess with it. Are there any AMD users out there that can provide me a "Welcome Tour" to AMD? Thanks in advance.
