I also had reset the bios to default and it almost worked but now it's just wanting to restart before windows finished to open

You want to wipe your HDD altogether and then reinstall Windows?

If so, follow this guide: https://www.techwalla.com/articles/how-to-wipe-a-hard-drive-from-bios

or this one:

http://www.liutilities.com/how-to/format-a-computer-hard-drive/

Both show the same thing, the second one is outdated, uses Floppy Drives, bleh. But anyway, the first one should be easy enough to follow. Let me know how it goes.

If you run the win 10 installer and do a clean install (see http://www.tenforums.com/tutorials/1950-windows-10-clean-install.html ) then as part of the process it deletes the entire drive meaning formatting drive before hand is a waste of time

win 10 installer: download the Windows 10 media creation tool and use it to make a win 10 installer on USB

MERGED QUESTION
Question from Wainruss : "Desktop but can't get passed windows loading screen"

Need to wipe an os I can't get passed the windows 10 logo nor can I restore or reset it just wants to reboot right after windows shows

Hello.

If you need to wipe the whole hard drive and clean the OS, I suggest going into Safe Mode. There is an easy way to do this: simply unplug the desktop, or flick the switch, when Windows starts loading. (when the small wheel turns) After 3 tries, windows will automatically go into troubleshooting.

You will see this screen, or similar.

Spoiler

You can then wipe the OS by selecting Reset this PC in the options.

Have you tried SFC /scannow?

is PC restarting before you get to windows? Its unlikely to be the hard drives since they are new. And resetting bios didn't help
You might want to run http://www.memtest86.com/ on your ram
