Question Random Freezing and Crashing Please HELP

[ItzTwaaa]

Hello gamers,
Currently trying to figure out this bottomless issue and I can’t seem to figure it out for the life of me
So on every single game I play it seems to work for 30 mins to a hour but anytime I get into any kind of fight or where lots of things are going on my game freezes up and crashes I have also gotten bsods all related to drivers and or memory
And it all only started happening after I replaced my psu and gpu
I have tried many things like changing the drive where the game is located I have tried lowering the settings and lowering the temperatures on the gpu I ran memory tests and all came back okay I went as far as putting another gpu in my pc and the issue goes away so any idea what the issue could be? I even tested both drives for faults and nothing at all
I am stumped
Update:
The specs are
I5 9400
32 GB DDR4 ram
TC-885 motherboard
GTX 1080 aero oc
750 watt Corsair 80 plus silver psu
I have tried reinstalling windows and also have tried installing newer updates from nvidia

Welcome to the forums, newcomer!

750 watt Corsair 80 plus silver psu
Corsair is the brand of the unit, while 750W is the advertised wattage of the unit and 80 plus silver is the advertised 80+ efficiency of the unit. What is the model of the unit and it's age?

TC-885 motherboard
Are you working with an Acer prebuilt?
