I'm fixing a pc for a friend, the problem being that it won't turn on (95% of the time) when pressing the power button. Earlier today I was able to turn it on with the power button just fine, then later it exhibited the problem my friend had described; no response from the power button.
The psu is fine, a light on the motherboard consistently comes on when I connect the power cord. If the pc had a reset switch (which it doesn't) I could just switch the front-panel wires around (which I can't anyway, since they are arranged into a mini-ide cable-esque connector). I'm having a hell of a time actually getting to the switch, so I can't physically fiddle with the switch itself. I'm at a loss...and it seems like such a terrible waste of time and money to buy a new case. She says the pc is 5 years old, and I don't know the warranty status right now. What are my options?
