IRQL_NOT_LESS_OR_EQUAL BSOD crash

I bought a new laptop a week ago for some minor gaming such as DotA 2 and online teaching using Skype. Recently, I have been experiencing blue screens of death and it says "IRQL_NOT_LESS_OR_EQUAL" when I'm having a video call on Skype. It doesn't happen all the time but it's starting to become more often. I was just wondering what the solution for this is.

System specs:
CPU - Intel i5 4510u
RAM - 8gb
Graphics card - Nvidia Geforce 820M 2gb and Intel HD graphics
Storage - 500 gb HDD

Update: I tried downloading WhoCrashed and this is what it says:
