Windows wont install properly

[DomC]

I have a 3070 dell XPS 8940 prebuilt pc and have since a couple of days ago been having trouble booting it up, it would be stuck in a boot loop and whenever it went into automatic repair mode, after a few seconds the screen would turn black, I didn't know what the problem was as dell diagnostics didn't detect any issues.

So I decided that I would just do a fresh install of windows, so I made a bootable usb but when I plugged it in, it would be loading for a few seconds but then would show a blank blue screen. Interestingly enough when I disconnected my hard drive, while it still won't boot, it comes up differently, whenever I try to boot off my usb it doesnt even get past the windows loading screen and keeps loading and when I try to "automatic repair" it doesn't go into a black screen like it usually does but keeps looping as well.

Lastly, might be irrelevant but when i changed the sata operations in bios from raid to disabled it would allow the windows setup to popup but make it unable to detect a drive.

And its definitely not the fault of the usb, it boots perfectly fine on my laptop.

 

Thanks, any help will be much appreciated.
