help RX6750xt constantly black screens then gets disabled

[BeastHotDogGUY]

first time this happened was maybe a month and a half ago, playing minecraft and had lossless scaling enabled then black screen. i noticed that whenever using lossless this happened bnut was told it was my error and not the program's so i stopped using it for awhile. now it just happens randomly it seems, everytime my gpu unistalls drivers, gets disabled by device manager, and gets marked as having a problem in device manager. 

today ive:

1. resat cpu, gpu, and ram
2. tested both pcie slots with similar results
3. tested with and without cabled extensions
4. unplugged and replugged my gpu cables
5. (ive also factory reset my gpu and reset cmos with no avail)

after doing all this i got rid of the error message in device manager untill just now. i was playing siege and while this may be unrelated i was unabled to shoot, melee, or uncrouch right before my game crashed after trying to close it.
my setup is:
5 5600G
XFX RX6750xt
32GB 3200MHZ TeamGroup ram
WD Blue SN570 as boot drive, 990 pro as other drive
ThermalTake Toughpower 750W
NZXT N7 B550
please help me
