My pc started off having problems booting up. I would push the power button and it would come on for a sec then shut off. After doing this 3 or 4 times it would come on saying windows did not shut down properly...blah blah, so I tell it to start normally and everything works fine. I turn it off last night and come back to it this morning and nothing. Try to turn it on, the fans come on and sounds like something else is running but black monitor and no light on the power button. Changed out ps and still same prob. Disconnected everything to connect one at a time starting with mobo same prob, no light fans running. Disconnected power switch and pluged ps into mobo and does same thing, fans run but nothing else. I don't know what else to try short of buying a new pc and I really don't want to do that unless I have to.
