\015 I just replaced the power supply in the emachine T3604. all is well and its getting power to everything now but nothing happen when I press the power button. I'm not exactly sure what going on with that.\015

Answers :

Do any of the fans spin at all, as though it's attempting to boot up? If not, then double check your power supply to see if it has a switch on it and if it does then make sure it's switched into the ON position. If so, then I would recheck the power connector(s) to the motherboard. If those are well seated then I would start looking at the power switch itself. Those go out from time-to-time. Unfortunately, several eMachine desktops of this model type that I've personally worked on had faulty components on the motherboard; which resulted in having to replace the motherboard. The typical symptoms are that the fans spin and it tries to boot-up, but then nothing else happens: no POST beeps, no video - NOTHING. I have had some of them that just wouldn't show any signs of power\\life. I've also had a few of this model type that just stopped working when the power supply went out. The likely cause of that is that the power supply will usually surge when it's dying out; which often results in burning out one or several motherboard components. Once you've reverified that all your cables are connected properly, but you still don't get power, find the 2 wires that connect to your power switch on the case (in your model it's usually the black & white twisted wires. Disconnect the connector, use a small flat-head screwdriver to touch the 2 pins that the connector was attached to. Be careful, there is electricity passing thru these 2 pins when touched together (jumpered), as well as the other pins if you accidentally touch the flat-head to another jumper pin. It should only take a second of jumping the 2 pins for it to start. If it still doesn't start this way, then I suggest replacing the motherboard. You can find good Micro-ATX motherboards on ebay for pretty cheap. If you still want to use your current processor, then make sure you get a motherboard with a CPU socket that's compatible with your CPU. I believe that your CPU is compatible with Socket 775.
