PC Crash as soon as nexus explodes on Howling Abyss [Crash]

This has been happening to me fairly frequently lately. The game will load up perfectly normally, but when the game ends, my computer crashes and my BIOS says that an electrical spike caused the unit to shut down unexpectedly. It has only happened to me on Howling Abyss so far, so I'm not sure if it also can happen on Summoner's Rift.

Interestingly, it seems to happen more frequently on losses. I guess I just have to stop losing.

I linked the log file for the game. I can't tell if it is of any use, but it's there just in case. Please fix this. Note- For some reason, the log file is only 1kb.. weird

I most likely will not reply to this post unless I notice it, so If you have any questions, message me in game please.
