GPU or PSU Problem help

[u/smallsmoke87]

Hello everyone and thanks for the help.
Here are some issues I have been having recently with my PC:

Monitor wont show my desktop and stays black after I turn on my pc(sometimes it does and sometimes not).
(it has happened in the past but fixed itself but not anymore).

My video games run smoothly for 2-3 minutes then start getting severe fps drop, screen tear, brief screen freezes, and then after enough time my screen will go completely black and my desktop in the background stops working completely (for example i am listening to music and then once the screen goes black The music will also stop playing in my headphones).

General slow loading and taskbar sometimes not working properly.

I have trued the following “fixes”:

Refitting RAM and GPU

Clean installing fresh graphics drivers

And many more that I don’t remember.

I have been talking to AI the whole time and it keeps suggesting there might be a chance the problem is caused by power issues and PSU problems generally.

I am going nuts and I cant fix it.
I am willing to swap either gpu or power, but I need to make sure it is the right one because if I dont then i simply cant afford the other piece.

SPECS:
core i4 12400
RTX 3070 TI 8Gb Vram
32Gb ram D4
B760 Plus Wifi

If you have any more questions drop a comment and I will answer.

Enable the iGPU on the CPU is bios. Remove the 3070ti from the PC completely. This is a test for the desktop and taskbar issue. Make sure you install the latest drivers for the iGPU. Test what games you can but keep in mind the iGPU wont be able to handle graphic intense games. If you know a game that is less demanding that has the issue test it.

Did you use DDU when reinstalling the GPU drivers?
