I7 12700k
Corsair 3200 C18 Ram DDR 4
MB B760 Tomahawk DDR4
Superflower Leadtek 1200w PSU
GPU Asus Pro Art 4080 Super.

Everything was running along fine until playing a few minutes of BO6 the screen went blank and the fans went on full blast, I was using a Z690 plus MB and I7 12700k, and a HX1000 PSU and a 3080TI, After this my pc would not boot, so i put in my old 2080 and the PC booted up ok, When i tried to play BO6 the screens went blank and fans on full again, So i tried another HX1000 PSU and it did the same, I have replaced the MB for the Asus B760 and this made no difference either, So i ordered a 4080 Super and it will not even boot up, So to summarize , I have tried two MB's and two PSU's and 3 GPU's, The pc will not boot up with the 3080ti or the 4080 Super but will boot up with a 2080 in but wont run games without screen going blank and the fans on full,

Thanks in advance

How are you cooling the processer?

I have replaced the MB for the Asus B760 and this made no difference either
Did you reinstall the OS after the motherboard swap? Also, what BIOS versions were/are you on for your motherboard?

i ordered a 4080 Super and it will not even boot up
You might want to see if the system powers up without the discrete GPU in the system. If it does, then your PSU is unable to deliver power the entire system needs when taxed. It could also be a thermal shutdown as your cooling is inadequate for your build.
 
Thanks for your prompt replies,
The system will not boot up at all with the 3080TI or the 4080 Super, but will run ok with the 2080, until underload a few minutes into a Game.
I never reinstalled the OS , I used the same OS
I am cooling the CPU with a 360 AIO Artic freezer ii
I have not updated any MB Bios as yet
