Guys really need your help. My desktop computer wont boot. When I switch on the power and press the power button on the cabin it powers up. CPU fan starts working and the power indicator led on the motherboard glows. The monitor led blinks green. It just wont boot. Its not the hardisk problem because I cant even see the motherboard screen, plus I did the same by disconnecting the hardrive and its still the same. And yes one funny thing. It boots when I place the cabin flat on the table, ie motherboard parallel to the ground. Any light into this matter would be greatly appreciated.
