Well I will know next time so could you stop telling wHat not to do and please help me.
Look I asked why it didn't make sense so I can see if I could help you understand then gave some advice on what not to do as well as what to do next time so if you would answer me rather then snap at me I can try to help.
Also is it making any beeping noises when you turn it on? Or is it just powering up but no noise and no post screen? Did you happen to smell anything weird inside the case like burning plastic?
It could be possible that you fried the CPU or maybe even the motherboard. If it isn't beeping and no post screen at all sounds like the motherboard.
