Well, this is a bummer. My computer is not wanting to turn on. This problem started happening after my taking out the video card and cleaning it, then putting it back in. I push in the button to turn it on, the green light comes on for a split second then goes off and the computer doesn't come on. It's so fast the fans don't even start up. Yes, I've made sure the video card is seated properly. SOMETIMES it will come on and stay, when it did that I went back to check the monitor cable being connected properly, as soon as I touched it, poof. Please help?
