BSOD every few hours, multiple errors, happens faster when gaming

This has been happening ever since I got this laptop, which was a very long time ago though it never bothered me as much as it has lately. Normally it happens after about 3-4 hours, or 5 if I'm lucky. Though whenever I play a game, it blue screens in about 1.5-2 hours. Though recently it has begun to crash in just an hour of playing a game and it's really beginning to get on my nerves.

I'll attach a few pictures of two of the blue screen's I tend to get, and will post more if I get anymore.
The most common error it gives me is "DRIVER_IRQL_NOT_LESS_OR_EQUAL" and "MEMORY_MANAGEMENT"

Thank you.
