[CRASH] PC and laptop shutdown

Oh Deer =)

My PC shutdowned sometimes while playing LoL (like 1 in 20 games). Symptoms: like a power failure, from one to the other second the PC just shutdown. (lights in the room are still on)

I thought: OK this PC is 4 Years old - so RIP ... i buy a new one ... ... ... i need it anyway ... but i want to play LoL NOW ... soooo...................... OK i carn't play LoL anymore on this PC but what about my laptop ...

So I switched to my Laptop that fulfill at least more then the minimum conditions for LoL (like my PC) too. I started a game ... on this laptop ... some minuts later .. BAM!!! same problem. And no! ... it was no power failure ... my laptop got a intact battery pack.

some thoughts:

• Both devices use NVIDIA graphic cards (750 Ti, 635M)
• I set up my lol client in a borderless mode on both clients,
• I play without vsync
• I play with colorblind mode (yellow bars ftw)
• The client on my laptop was just clean installed
• i installed the Java SDK for Eclipse and C++ redists for visual studio
• Both times there was a video on youtube running in the background (firefox)
• stable internet connectivity (wire) PC and Laptop
• Windows 10 on both devices
• both times i played Janna (Jannas are the key!!!) ^^
• Running: Firefox, Steam, Skype, Teamspeak3, Windows Defender (only), OneDrive and the default Windows Apps on both devices while i play.

I am not really intrested in leaverbuster punishes so pliz tell me if i should play or not. If you need further information about my systems just write.

dont judge my english - pliiiiz
