arc A770 has become unusable after a couple of months , help me please

[Deagle_]

i always had little problems with my a770 , but now it has become unusable , after i installed new drivers , currently ver 31.0.101.5084 , when under load , in 75% of the games i played it just crashes the whole pc ,

i get a black screen on both of my monitor , i can keep hearing sound , like discord channel for example , but they can't hear me , and the only thing that i can do at this point is keep pressing the on/off button to shut down the pc and turn it on again ,

the time it happens vary , even 2-3 times in a row just after rebooting, or just once and then no more for hours , yesterday i was playing war thunder , and i just kept crashing , like 4 times in a row in the span of 10 minutes , i'll leave here what kind of components i have :

CPU : intel i7 12700kf

MOBO : nzxt z690

RAM : 2x16 DDr4 Viper rgb 3200

storage : 1 nvme 250 (kingston) , 1 nvme 1tb(samsung 980pro(recently added 15 days max)), HDD wdblue 1tb , HDD seagate barracuda 2TB

water cooled with corsair H100i v2

PSU : corsair VS650

it has windows 10

GPU : arc a770 8gb (Asrock phantom gaming) ,

i initiated a RMA with the seller (i had the card for like 5months) , but i have to wait till the first couple of days of jenuary , but i'm kinda scared they won't find any problems since they are very probably softwere driver problems and i wasted 50 bucks more or less between sending it and such , what could i do? , i used to have similar problems but they were a lot more scarce , and they resolved itself in a couple of weeks ,

now i even completely formatted my pc , even tho it wasn't long since the last complete one , more or less 4 months , and after an entire day of playing tarkov , the pc didn't crash even once , but as soon as i run a game called medieval dynasty , it asked me to download directX , and after literaly 30 seconds it crashed again , this situation is very stressful and i'm regretting my gpu choice .... 

what do you think what could i do? 

i add that i used whocrashed to read windows dumps , but there were no dumps , i think it is technically because the system is still running when it blackscreens , i have to shutdown the pc manually , but otherwise the screen stays black even waiting several minutes ...

After starting the game, the computer resets.

so I initiated the return process and it was approved. tomorrow they will pick up my a770 and refund my 350$. anyway, I'll take the 5070 ti...
