So I just bought a new computer, this is it: https://msi.com/Laptop/GL63-8RD.html
I installed Xubuntu 18.04 LTS on it using a bootable USB, and I selected all the options to download updates and third party software because I know Nvidia graphics can be finicky. Everything seemed fine when I was trying the OS with the USB, but after installing the problems started.
I boot into the OS just fine, insert the password to unlock the disk and then my user password normally. Then after logging in if I try to open something like the terminal or the web browser the OS crashes without warning, and then I can move the mouse but nothing else, if I click on an icon with the mouse nothing happens, I can't open the terminal with Ctrl+Alt+T and can't shutdown with Alt+F4, only thing I can do is move the mouse and shutdown the computer by manually pressing the power button for a few seconds. I then tried to boot into the OS and not open anything, just to see if it crashes, and it did but this time it gave me a nice error message. These are the details:
watchdog: BUG: soft lockup - CPU #6 stuck for 23s! [gvfs-mtp-volume:1639]
Your system might become unstable now and might need to be restarted.

Ubuntu 4.15.0-22.24-generic 4.15.17
Linux 4.15.0-22-generic x86_64
No upgrade log present (probably fresh install)
After I sent the report, I couldn't do anything with the computer. By the way, while I was typing this there were like 4 or 5 other errors saying "System program problem detected", but I didn't open them and now there is a new error message but when I press Report Problem with the mouse it doesn't respond.
What can I do? Right now I can't do anything with the OS, it crashes every single time I boot after just a few seconds.
