Question Black screen and game crash

[jibob]

Hello everyone ! ive had some issue with my pc for a little moment .

When im starting a game (im mainly playing COD and Arena breakout ) everything runs fine , but after 1-2 game , the game just crash and i get a black screen for a few second and everything go back like nothing happen .

I tried many thing :

• Going back to windows 10 , going back again on windows 11
• going back to the old version of the gpu driver and after trying that i installed the new one
• did a memory diagnostic
• checked the hardware to see if something was not tight
• i brought the pc to canada computer to get it checked , he said that everything was running fine but the only thing he could see might be the power supply wich could maybe not give enough power to the gpu

the only place i get an error is on COD : its a directX error with numbers but when i look it up the answer to solve the issue is always different and i tried most of the things , heres the numbers : Error code : 0x887A0005 (0x887A0006) (6068) D

Like i said up there , the guy said it could be the psu but i want to make sure before buying a new one for nothing .

Heres my specs :

CPU : AMD Ryzen 7 7800X3D

GPU: AMD RX 7900 XTX Red Devil

Power supply : corsair SF750

Ram : G.Skill trident Z5 RGB 2x16 DDR5 6400 ( set to 5900)

the problem does not come from heating , i did many stress test and everything was fine on that side

If someone could help me i would be forever thankfull , thanks !

(p.s : english is not my main language , please dont be to harsh on me )

UPDATE : just changed the PSU for a 850W and still happening
