PC won't turn on

  1. First of all, Hello and thank you for being kind helping souls.

    I just upgraded a machine of mine, (motherboard, processor, power supply and RAM) and I'm a little scared I might have burned something.

    I accidentally left the 4 pin 12v plug out before trying to start it (with the old power supply). The computer turned on (fans, lights, monitor feed) but did not respond. Since I couldn't turn it on on the button, I pulled the power plug. A few times.

    After a while the computer wouldn't even light up. I got a new power supply, and connected the 4-pin 12v plug, but I'm affraid it might be too late. Nothing smells funny, though.

    Can this be a self-preserving shut-down reactivated by jumper switching or is my brand new motherboard gone for good?

    I gotta work tomorrow, so I'd really appreciate any answer soon.


    My PC:
    motherboard: PC Chips A33G
    processor: AMD Athlon 64 3000
    RAM: DDR2 512 533
    2 HDDs
    1 DVD
    1 floppy

    thanks again

    Ok, so I tried fiddling around with the jumpers.

    The CLR CMOS jumper settings are the following:
    ooo 1

    I suppose jumper 1 is the one on the right.

    1-2 short: Normal - oHH 1
    2-3 short: Clear CMOS memory - HHo 1

    I tried starting with the normal mode, with originally started, but it's non-responsive.
    The 2-3 setting mode, however, starts the computer, just as no shorting at all starts. But even though it turns on, with all lights on, and fans and everything, I still have no image in the monitor, and all the lights (except the DVD-RAM) are on all the time.

    I don't know what to do, something is very eerie about this. And I have to wake up in 4 hours to go to work.

    Thanks again in advance
