burn two max 10 in 2 hours, someone please tell me the power on/off secquence

You should be able to power your board on or off with a USB-Blaster connected.

Why do you think your devices are "burn"? Do they now get hot? How much power do they take? Or is it that they just don't program?

Look through chapter 2 - "max 10 power management features and architecture" in the "max 10 power management user guide (https://documentation.altera.com/#/link/myt1393986555723/myt1393987293874)". Look at the "power-on reset circuitry" section - page 2-4 and figure 2-3. MAX 10 devices monitor certain rails before allowing you to program the device. VCC, VCCIO & VCCA must power up within the ramp time (Tramp). If they don't the device will not allow you to program it. Is this why you think it's not working?

Cheers,
