Question Cant exit BIOS on newly built PC

[Juicymarmalade]

Just finished my build but when I power it on it goes into BIOS. When I try exiting, it reboots PC but goes to the same BIOS screen. I have an SSD with Windows 10 installed in the first SATA slot and a normal hard drive in the second(I've already tried switching them around and removing HDD). The BIOS screen shows all my parts connected including the SSD, HDD, RAM, CPU etc so I dont know why it wont boot.

Also when I boot my motherboard has a white light that cycles past where it says CPU, RAM, VGA, and then stays on "BOOT". Is it normal for light to stay on or is it telling me something is wrong with booting?

Only other issue I can think of is maybe my GPU. I was having trouble getting my display port connecting earlier and even now, when it boots to BIOS it shows "No DP" on monitor a couple times before going to bios. Also, my GPU fans stop spinning shortly after bios. Not sure if thats normal for 4070.

Anyone have any other ideas why I cant boot to windows? thanks

My Specs: (checked PCPartPicker for compatibility)

GPU: Gigabyte Windforce RTX 4070 12gb

CPU: AMD Ryzen 7 3700X 3.6ghz 8 core

Motherboard: MSI B550-A PRO ATX AM4

PSU: Corsair RM850x

SSD: Samsung 860 EVO 1TB

RAM: Teamgroup T-Force Vulcan Z 16gb

you need a clean install of windows. only have the storage device connected that you will clean install windows on.

any way to use the windows already on my drive or do I reallly need fresh install? Will this wipe any data?

Yes fresh install with only the target OS storage deviCe conected. NEW BUILD NEEDS A CLEAN INSTALL.

SOLVED. Just switched from UEFI boot to CSM and got into windows just fine. No fresh install needed.

I'm guessing you'll experience more problems if the Windows 10 install was configured for different hardware.
