TOPIC: Power outage, now my cpu turns on ?

Hi,

We had a power outage about a week ago and I had turned my cpu off since it was a planned power outage. I had it plugged into a surge protector and all that. The next morning when I went to turn it on, all of my LED lightes came on, fans turn on (to include the cpu fan) and then it just dies like there is no more power running through the system. No bios screen, no chance to load anything. It had been working fine the night before and for the previous 6 months without a hitch.
I'm wondering if the power outage could have fried my whole system or is it just likely my power supply and how can I (a non techy with limited resources) test to see what the problem is?

Please help.

I didn't find the right solution from the Internet.
