Update on computer crash · 4:22am Mar 28th, 2017
I did some snooping in the Windows Event Viewer under system logs. It seems like it was indeed partially the fault of the multiple Youtube videos, as there were long strings of critical errors related to the network. Though, it might've been due to my internet connection.
Aside from that, it seems like the cause of the crash was a device driver that got corrupted in memory, causing the system to hang.
