PC Crashes In Specific Areas Randomly

Alright, so I have a generally very powerful custom built gaming rig, yet out of nowhere, my PC will suddenly crash without a BSOD and only going black and instantly restarting. My issue though, is that this only happens when playing League of Legends, and I've noticed a pattern of it MOSTLY happening while I'm in or around the bottom side river in Summoner's Rift, and I believe I've only crashed in ARAM a select few times. As well, the event viewer lists the crash issue as a Kernel Power 41 error, and I've looked for various and many fixes for this or as to what the issue may be, but I have not succeeded. (As well, of course, nothing seems to overheat during gameplay in LoL, especially when I can fluidly play games like WD2/GTAV/RS:S at ultra 60FPS or higher without any issues.) I'd also like to add that this does not happen every game, only on occasion.
