New PSU (Corsair RM1000x) paired with GPU (5070ti) - System powers down instantly upon opening Windows 11 screen.
Just set up new hardware. I verified the connectors and tested both monitors—1080p and 1440p. The BIOS functions properly, everything lights up and operates. The fans are working correctly. When I see the Windows 11 screen and log in, the display disappears and my mouse and keyboard stop responding. The last time I powered it on, it reached the login screen before the screen went dark. Hardware appears to be functioning fine. For the GPU, I’m not using the included adapter but instead the PCIe power cable from the PSU. It has a dedicated slot labeled something like a 12+4-pin PCIe connector. It seems like a software problem—possibly a driver issue. If anyone can assist, I’d really appreciate it. Thanks!
