Its about an H5U20ET#. Although there is a green light on the mainboard, pressing the power button doesnt show any effect.

But if it were the power supply, there could not be a light on the mainboard? 

Ive already tried a hard reset, but without any success.

Does anyone have any other idea how to get the PC working again?z

Thanx in advance.
