I just bought a new game, but unfortunately it causes my PC to hang while starting. Examining /var/log/kern.log after forcibly rebooting (ie. hitting the reset button) shows a few of the following errors:

I'm not quite sure what this could mean. I'm reading this as the system running out of RAM; however, looking at the game's minimum system requirements (required 6GB, PC has 8GB), the PC should have enough. On the other hand, my graphics card (Intel HD 4000) is not officially supported, but this doesn't seem to be related the error.
Am I really running out of memory here? Is some hardware likely defective? Or is it the integrated graphics?
The system is a fairly up-to-date Ubuntu Artful:
~ lsb_release -a
LSB Version: core-9.20160110ubuntu5-amd64:core-9.20160110ubuntu5-noarch:security-9.20160110ubuntu5-amd64:security-9.20160110ubuntu5-noarch
Distributor ID: Ubuntu
Description: Ubuntu 17.10
Release: 17.10
Codename: artful
Typical memory situation before starting the game:
~ free -m
total used free shared buff/cache available
Mem: 7678 1321 3992 343 2364 5758
Swap: 7883 0 7883
Edit: I've been continuously running free -m until the freeze; this is the last entry:
total used free shared buff/cache available
Mem: 7678 3986 129 3348 3562 104
Swap: 7883 42 7840
So, while it does seem that the system is really running low on memory, there's still plenty of swap left...
