Solved Need Help with Windows Installation!

[BlazeFury27]

I’m pretty new to all this and not super tech-savvy, but I decided to dive into building my own PC. Things were going great until I hit a problem while trying to install Windows 11. The installation starts, but just as it begins copying files, my PC completely shuts down. I tried Windows 10 as well, and it gets a bit further (reboots to start setting up), but then it shuts down too. Could really use some help. Any ideas on what might be wrong?

It sounds like you might have a power issue. Double-check that all your power supply connections are secure, especially the 24-pin and 8-pin connectors to the motherboard.

Sudden shutdowns during installation can often be due to overheating or power supply issues. Make sure your CPU cooler is seated correctly and that all fans are working.
