The manual for that motherboard says to use DEL to enter bios, so forget about the other keys for now. (it should say during post what key to press)

Don't hold the button down the whole time during post. Press it, and release. And keep repeating that until bios opens.
If you see windows start to load then you missed it, so press CTRL+ALT+DELETE immediately to reboot. You don't have to wait until windows has loaded.
Just keep trying several times.

If that still doesn't work then try f8 and f2 too, just in case the manual has it wrong.

If you have an old keyboard with ps2 connector then try that instead of using a USB keyboard.
