Pc post issues

[calieburger]

Hey guys. 

I have the weirdest problem.

so what happens is I did some maintenance on my system by cleaning out the dust and so forth. When i was done i hade the strangest problem my pc sould just not POST. There is no post screen but the weird thing is is that when my pc is put on its side the pc would port and startup just fine. I disconnected and reconected all the cables, I went as far to take my whole pc apart and build it again with no luck. 

Any help will be much appreciated.

 

Thanks guys

Probability 1 : The on switch is half dead.

Probability 2 : Something is loose.

I can't kid you here but i managed to revive my 6 year old pc by kicking it.

Motherboard is most likely half dead. If not the motherboard, then the ram.

Check for a loose wire in the Power supply connector to the motherboard header and the motherboard 4/6 pine power connector. Test by having the pc upright and gently "push" or wiggle slowly the wires going into the motherboard headers. BE EXTREMELY CAREFUL AS THIS IS A SHOCK HAZARD!  I will not be responsible for damage to the pc or you as a result of shock. Be careful as this could produce a surge to the motherboard and kill it or you could be shocked.
