    When I upgraded the power supply the computer booted up fine.
    Few hrs later, came back... shut down computer and reinstall new rams and now computer will not turn on. I took out reinstalled the old power supply and still will not turn on. I reinstalled old ram without new rams, still will not turn on.

    I checked for loss connector and still not working, no beeps, nothing...

    Motherboard and the power supply has steady green light (No blinking just still green)

    I own gt5014 and no fans turn on.

    Maybe the back fan is bad and loading the system down if it is plugged into the board.

    The motherboard appears to have an electrical short

    How to troubleshoot a dead motherboard

    First, check to be sure the power supply is switched to 120 V.

    If it is, then do a minimum system configuration test. Turn off the ON/OFF switch on the PS back panel, and disconnect the cord. You don't want to work on the motherboard (MB) with standby power applied.

    Disconnect all components from the motherboard (including floppy, CD, hard drive). Leave the power connector attached to the hard drive, as the power supply has a minimum load requirement (never run a switching supply without a load, unless it is designed to do so -- and few are). Remove the power connector from the MB, then reinsert it (potential for bad contact in control circuit). Remove the RAM, reinsert one stick (going for a minimal configuration). Remove all PCI boards and AGP. The motherboard should be able to turn on and beep an error code even without RAM and video. Plug the PS back in, turn on the back panel switch, and use your screwdriver to short the power button pins (ATX type of supply). Double check which pins are the power switch pins in the documentation, as front panel attachment point functions are usually not obvious, and are easily miswired since the connectors come off so easily during maintenance.

    When you touch the pins, the CPU fan should instantly start turning, and shortly thereafter, the MB should beep an error code.

    If not, check the mounting for the MB. Some cases use a U shaped rectangular snap in receptacle for MB mounting screws. These commonly become bent or twisted, and can short out nearby traces sometimes resulting in dead board symptoms. If the fan didn't start turning when expected, you probably want to repeat this minimum configuration test with the MB out of the box. Put it on an insulated surface (e.g. pink packing foam or cardboard), being careful about electrostatic discharge (ESD) (however, my bet is ESD damage that disables a motherboard is rare).

    Although I haven't seen it, your MB may require the video card to be plugged in to turn on. I doubt this, though, as there is enough housekeeping to do before checking for the video card that the fan should have time to start to spin.

    If it still isn't working, try the other memory stick, or remove all memory.

    I had a "friend" with this symptom who had plugged in an IDE drive connector upside down, causing a direct short that made the PS shut down instantly (without harm to any components). Double check all connections before applying power!

    I think I got ESD because don't supposed to plug the white part where the fan goes and which I saw smoke then next day computer still works then few hrs later it stopped turning on. Not sure why it stopped now since in 2006 after 3 months of owning it, my desktop was burning up with smoke and the only thing that died was my speakers but the motherboard is fine.

    So my guess no way to fix ESD?

    I just want to get the files out of the hard drive and transfer it to my laptop hard drive.

    Sorry, there's no cure for damage caused by ESD. Google it, if your not sure what it is. Sounds like you may of burned out a part of your motherboard. Did you try testing it, as instructed?

    Here's a video to explain how to transfer files from a dead computer.

    But, don't tell anyone, it's a guarded tech secret.
