I got it to work with jumping it with the screwdriver, thank you so much 
 

If you have a drive with windows installed already it should boot. To update BIOS you need flash drive to Flash your BIOS. Go to you Motherboard manufacturer web page and look up the model motherboard. Find the support page for it and there should be downloads and instructions on how to flash BIOS to most recent version.
 
So far as Windows it is locked to the Motherboard of the system is was originally installed to. You would need to try and transfer the license using the steps outlined above. You can try it without reinstalling windows. If that does not work you can try to contact Microsoft Customer Support and if necessary you can create a windows install bootable flash drive on any computer with Windows 10 (just google Windows Media Creation Tool). Then you can fresh install Windows. If you choose this option make sure to pull any important files off the drive first as it will need to be formatted to fresh install Windows.

You should just reinstall your OS
 
You might have the key linked to your microsoft account, otherwise just call to activate or something when you reuse the key.

Assuming you are not changing your SSD/HDD, just plug it in, and you are read to go. Windows 10 will detect the new hardware as it loads (you'll notice a much slower startup time), install drivers, and adapt itself. Once done, do Windows Update to get the latest drivers, and anything missing, and you should be ready to go.
 
That said, Windows 10 will now be deactivated, because the motherboard was changed.
If you have a retail copy of Windows 10, you should be able to re-activate it once again by going to Start > Settings > Update & Security > Activation. Maybe a phone activation might be needed, but it will work.
 
If you have a OEM (Dell, HP, Acer, etc) or system builder OEM (the ones you can buy at computer stores, like Newegg) license then you cannot transfer them. It is part of the lower price. You'll need to purchase a new license of Windows, which you can enter its product key in Start > Settings > Update & Security > Activation, and you'll be up and running.
 
For best experience, and ensure the highest reliability, it is best to clean install Windows 10.
 
Note:
- If you pass from BIOS to UEFI, or your old system was installed on a UEFI based system but set to Legacy mode (emulates BIOS), then you won't be able to start Windows 10, You'll need to do a clean install. This is because BIOS only works with MBR partition layout, while UEFI only works with GPT which is the new stuff for drives.
 
- If you set your old BIOS or UEFI SATA controller to emulate IDE/Legacy (to emulate the old fat ribbon cable), and now you have it set to AHCI/Native mode, then Windows 10 will also not boot, as it was configure for these age old systems using IDE cable. A clean install install is required.

I'm going to preface this by saying I assume, since you used USD, that you're in the US. If not, let us know so we can adjust for your local currency

Right now GPU prices are like 2x to 3x in most cases their normal price and the CPU will have more impact.
