Windows 7: Upgraded motherboard and cpu, no keystroke will load bios setup

I have no idea really. Have you double checked all connections? Sometime a dumb thing causes issues, I've had a few of my own.

check that the keyboard is actually powered, quite a few mobos had a jumper to power the USB ports when the PC is shut down.

PS/2 keyboards did save my backside quite a few times in situations like this. Check if there isn't a jumper for PS/2 power too.

Otherwise your only hope is forcing it to detect a big hardware change (i.e. remove processor from socket), and at that point most mobos will stop POST and give you a key to press to enter bios to re-config.

I would try reflashing BIOS from windows, before doing that though.

Note that depending on how the BIOS is made/screwed up, the last two lines of advice might lock it up permanently, so proceed at your own risk.

I agree. Contact your motherboard support and ask about flashing the bios pending an RMA. That way if it bricks, they will still give you an RMA.

Absolutely agree mate I have used one many many times to get a machine booted when all else fails. Same goes for the mouse too!

I am at a loss as to why but perhaps it has something to do with a legacy thing??

However it does get it going and from there it is usually ok with the ordinary KB.

Now if this doesn't work then it looks like some support from Gigabyte.

This makes for some good reading too if you can get to maneuvering with the PS2
Ps/2 keyboard works during boot up but will not work when windows is open! - Prebuilt - Systems

So it might be worth a quick scan with these

If you're getting the Windows Boot Manager then you've waited to long. The BIOS Setup key must be triggered before it passes off to Windows.

If it still won't trigger with the HD unplugged then you likely have hardware problems or are using the wrong key. Which is the key given on the first boot screen for BIOS setup?

Reset the BIOS to defaults, make sure Fast Boot is turned off.

Also wanted to mention, some bios have a fast boot option that will not allow you to get in the BIOS. Not sure about your board, but with mine I have the fast boot option and when enabled it does not allow the delete key bios entry. MSI has click bios, where you can enter the bios from windows. If your board has something similar, try that and check the bios settings.

XX Mate as Greg pointed out the BIOS has to be gone into before it even goes any further so try tapping the DEL and then while still tapping hit the power on button.

That motherboard gives the boot device menu with F12. In some motherboards you have the option to enter BIOS also in boot device menu.

In my case this laptop had the delay to press key to enter BIOS set to 0, so I had to first enter the boot device selection menu, and from there select BIOS to set a few seconds delay.

I have come across a simular situation to this before.
Keyboard manufactures can use different coding with the communication to the M/B.
Please try any Microsoft K/B (USB is fine).

Today F2 and "Delete" do the same thing and yes F8 for boot menu.

Well I agree and they all come with their software but I still reckon using the PS2 is a no brainer.
