Videogames keep crashing

[Elderpycake]

Hey guys, so i've always had this problem with my pc. Whenever i'm playing a videogame it crashes after a few hours of gaming, overwatch, fortnite, etc..

The game freezes and then it closes with a crash-notification. when i'm playing fortnite it freezes and then the unreal engine 4 crash message pops out, same thing with overwatch but with another message saying "rendering device has been lost", i've also encountered some BSOD crashes, specifically the MEMORY_MANAGEMENT crash, this has been annoying me for over a year and I don't know a single way to fix it. 

Also this crashes are happening constantly after I upgraded my GPU (which is a nvidia gtx 1050ti), and know it's starting to annoy me even more.

 

I don't have an excelent rig but here it goes:

CPU : Intel core I7-7700

GPU: Nvidia GTX 1050ti 4GB

Motherboard: BIOSTAR H110MGC

PSU: you probably don't know this brand, it's from the country where I reside    SPEEDMIND 800W GAMING PSU

RAM: 16 GB DDR4

 

Any help would be really appreciated!

so yeah thread solved? lol

you can check your temps if you want but sounds like the psu just hiccups and the gpu crashes as a result but not enough to crash the whole machine

 

doesn't even look like its 80+ anything at all
