After using Ubuntu 18.04 LTS on this PC for about half an hour, it suddenly locks up and stops responding. I try Ctrl-Alt-F3 and login, but any command entered hangs, eventually showing an error task blocked for more than 120 seconds.
Just ran a memory test and everything came back fine but IDK I'm still convinced it might be a hardware issue just because of all the other problems I have. Such as the computer sometimes boot to a black screen no bios logo or anything or the several other questions I have posted here in ask ubuntu such as an issue where the computer would randomly fail to load my profile getting stuck in a black screen askubuntu gnome-black screen or me having issues with symlinking my user folders like Documents to my SSHD and then getting high CPU usage and freezes ask ubuntu issue with symlinks I don't know how helpful the output I posted of my system specs would be as it got cut off but I do know my specs from memory as I built this computer.
