    Ok so here's the situation :

    my friend's PC suddenly stopped working something like a month ago. He took it to some local computer repair shop who diagnosed a dead mobo and PSU. :eek:

    They told him his mobo was now impossible to find and since I could get my hands on one fairly easily he asked me to repair it for him. :cool:

    So basicly I changed his PSU and ordered a new INTEL D865GLC Socket 478 (his mobo)... I just received the damn thing and even with the brand new mobo the PC does the exact same **** :mad: :

    I press the power button and absolutely nothing happens, nothing! Even the fans stay idle :eek:. What could be the cause? I even tried shorting the POWER SW pins with a screwdriver to make sure it wasn't the case Power Button but in vain.

    I tried swapping mem sticks, changing PSU, tried removing HDD, DVD drive and GPU... no help there either.

    Could it be a dead CPU? :confused:

    stay simple have you checked the cable and the outlet to mae sure power is going to PSU
    even with a dead CPU it should try to boot and either go nowhere or turn back off

    Yeah all the cables are properly connected to the mobo.

    When I press power it's really like I'm not pressing anything. Absolutely nothing happens. No sound or led blinking whatsoever.

    There's that little green led on the mobo however that's always lighted up when the PSU is on.

    have you tried with and without the 4 pin power
    I have had systems that would not boot with it hooked up
    and some wouldnt work without it

    Here's the answer I got on another forum :

    *******************************************************
    Yes, nothing will start without the CPU.

    The one thing you should have on the intel MB is the standby power LED, when the power supply is pugged in and turned on, if not there are other issues.

    If both the MB and PSU where faulty, it would be good to try and find out how/why as it may have damaged other items (CPU, RAM, GPU, etc).
    *******************************************************

    Does that make sens? That means his CPU is dead, right? I just don't feel like buying another piece of harware that's not even faulty...

    Personally I have never seen a dead CPU cause that.
    I have always seen at least the fans come on for about 3 seconds before a shutdown or hang-up

    did you read what i put about the 4-pin power

    4 things.

    #1-Have you tested the power supply you purchased?
    #2-As wizkid59 asked is the processor auxiliary +12v power connected?
    #3-What is the processor sSpec number?
    #4-What is the board AA number?

    Has anyone solved this yet?
    I have had 2 of these eMachine/Gateway 310S models present the same symptoms to me.
    To save all the trouble of posting suggestions that have been tried - For the PC I am currently working on, I have:
    replaced the PS
    • ,
    tested the on/off switch
    • ,
    removed /replaced the CPU with a known good CPU
    • ,
    stripped the board of all memory, pci and drives
    • ,
    removed/replaced the CMOS battery after 4 hours
    • ,
    checked the mobo for swollen/leaking caps
    • ,
    checked connections for snug/snapped in and tight.

    At each of the above items, I tried to put power to the board and pushed the start button. The board shows no sign of damage or burned components at 5x magnification.

    One other note that may be useful for troubleshooting... The OEM PS was bad when this machine came in for repair. Two known good PSU's were tried, each with same result - Power to the board results in green led (on board near the memory slots), but no other signs of life. (and no green or orange LED on front panel power buttons.

    It's just a cheap PC, so nothing risked either way, but I would like to know what's happening here. I can't stand to be beaten by a machine....

    OK You may think I am nuts but I have seen this twice both on Dells. One situation was Dell is retarded and says is normal. Everytime this particular PC is turned of I get a flashing orange power light with no response to pressing it. Fix: unplug power then remove CMOS battery wait until motherboard power light goes off then put battery back in and plug back in wait abut 10 seconds then turn it on. Second situation is same thing flashing orange light but no response to power. Fix: one of the USB connectoers was shoprting out had to keep wiggling them until I found which one then no longer used that one. Let me know if this helps any.
