How to do factory reset on my tablet?

[Karthik013]

I recently bought milagrow tabtop 7.04. Its a 7 inch tab with 4GB internal memory. A few days back it stopped booting. Whenever I tried to power on it only android logo is displayed. I want to know how to reset it as it has no volume rocker keys. It has back, power and option physical button. I have tried all combination of buttons to no success. Please help.

Hold Power button for about 30-45 seconds, it should do forced reboot.
