I use Windows 10 on my default ssd drive. I first installed Ubuntu to my secondary hard disk in summer 2019 and there were no problems. Then I installed it again several months later (because the partitions ubuntu ran on were formatted) and the computer started to frequently restart. I checked the temps, looked through the logs, checked if ”secure boot“ and “fast boot” were disabled and there were nothing suspicious. Few days ago I installed Elementary OS to that same hard drive and the problem still persists. This also happens on live usb and one time it restarted right in the middle of the installation of the OS. I’m not sure if this is a hardware problem because Windows runs absolutely fine. The restarts usually seem to happen like 10 minutes after I first boot up linux. Any suggestions? Thanks.
