Hi there.. i have acer aspire one model. Its not turning on. I tried every method. Problem is when i press the power button, motherboard makes noise like beep beep beep, fan also not working. Beep comes only when i press the power button. Charging port, RAM, Hard drive, Battery everything is ok. This beep beep sound is different from the memory beep sound.

Thanks
