New PC Build wont boot Windows

So I just built this PC yesterday and everything was going fine. Everything turned on fine when it was in the case before I even hooked it up to the monitor. I went ahead and plugged in my Windows 11 USB, but when I turned on my monitor, it said DP No signal found. I made sure it wasn't plugged into my motherboard, but it still showed no signal found. Then, after turning the pc on and off a few times, my monitor would go straight to the BIOS screen and even after I exited it would take me right back to the BIOS. I enabled CSM after it was disabled cuz I saw it could help I was kinda desperate but that didnt do anything. I checked the boot tab and it didnt seem to be detecting my Windows usb. I tried the usb on my laptop and it showed up fine. No debug lights on my motherboard either. I tried again today and its not saying DP No signal found today but its just a blank screen now. Not even bios is showing up. I kept pressing del but BIOS isnt showing up. I was thinking of putting windows on another usb since I have the product key but Im trying to figure out why the initial one isnt working. Has this happened to anyone?
