Hardware PC Crashes Due To "Heavy" Gaming

[Berthenk]

Ah, yes, you might say it's overdue but I was planning on upgrading anyway so not much is lost.
Also, it seems I forgot to say that that's not my computer. My PSU does have a fan but it's mounted incorrectly so it blows upwards instead of downwards. Still, that does not do anything about the horrible airflow.

Its probably becaus of overheating.
