Thank you sooooo much, it works now. I have never heard of something so simple. Does this reset everything?

it resets your bios settings, anything on your hdd will work just fine but anything that you change from normal settings in the bios will be taken back to defaults. this only affects things if you need to have your bios setup a certain way but as it would seem some of the settings or one of the settings was improperly set.

Didn't read all the suggestions sorry if someone already told it.Try pressing the button on the back of the box or replug a few times the power cable.If nothing happens it's probably from the power supply I'd suggest to go visit a specialist 'cause you are clearly inexperianced and might screw something up
