What have you tried so far?

Make sure the PSU is turned off and that the power is unplugged first.

Can you open open the case and clear the CMOS? Also see if there is any component or piece of hardware that looks fried or strange. Please also check to make sure that the case is as dust free as possible and that all components are completely secure (Not loose).

Check the memory and make sure properly seated.
With this being an all-in-one PC you will need to remove the back cover to get access to the components.
