My acer aspire AX series

I have an acer aspire AX1470-UR31-P series desktop computer that is only a little over a year old. Last night we had a storm pass through that knocked out the power for a good 4 hours but the computer was on generator power within the time frame. I went to work leaving the computer off when I came home in the morning to turn the computer back on the power button didn't work. Nothing turned on it was silent. I know the monitor works and I took the power cord out of the computer and switched it with the monitor on so I know it's not the cord. Its not the power strip cause everything else would be off as well. Please help thank you
