Hello. I have a Asus tuf 4080 RTX 16 gb in the specific machine
Asus Creator Z790 pro wifi, 64 GB Ram, Intel Core I9-13900K powered by psu corsair RM 1000x.
Suddenly my PC, with no reason, started for a lot of times to restart. I thought it was windows update. But it was not. I tried to play some games, sometimes was perfect, sometimes machine was restarting. Everything including bios was updated and windows 11 pro 64 bit etc.
I tried with another ssd(new one), clean install, then the same problems.
I have to mention that my room temparture is only 22Celcius, motherboard about 28, cpu never more than 90. Nothing is overclocked. Then i tried some 3dmark tests, sometimes was perfect, sometimes, restart again and again. I borrowed another psu, but the issues were the same. Then i checked gpu-z and noticed that sometimes the speed was pci x8 1.1 and not 16. I changed the vga slot and i had no more crashed but also the speed was x8 1.1.
Card is NOT Rised.

Please help me !!!!
 
Now, the PC, does NOT boot, when i have the GPU in the up pci slot. Only in the down one
But when it is at the down slot, it can run games, even 3dmark, but with low scores and lower graphics......
