When I turn on my pc it sound like it's starting but it doesn't, Only caps lock and f12 light on,but not flashing. I believe it might be because of temperature abuse, I left it on hibernate for 2 nights and then I turned it off, and when I wanted to turn it back on the next day screen stays black. Motherboard doesn't seem damage or burned. What could be the problem? How could I fix it?

It can't be hibernation. Hibernating saves everything in memory and does not use power, from my knowledge. It may be a non-responsive connector or the power chip(a small chip placed under the power button). Same thing happened to my sister'sold toshiba laptop.
