  1. Hello hardware gurus!
    I have some weird problem. I took off the case from my machine. Then I replaced the floppy drive. The I connected back the power cable back. Once I did that the fan went "booo" and then goes silent (please note that i didnt even touch the power button yet). Then I connect the rest: keyboard and monitor. However, once I press the power button, nothing happens: no fans, nothing....
    I'm so upset now. I need some really good suggestion/advice on the next step. Please assume that motherboard replacement will be the last in my list, because it's so pricey.

    Reset your CMOS. Try again.

    Why were you replacing a floppy drive?

    Nobody worth listening to would suggest a motherboard replacement without many more details and troubleshooting on your part. So you don't need to tell us what we can and can't do.

    Sounds like BIOS was set to turn power on after a power failure, at least it would explain why you didn't need to press the power button.

    Check the PSUs (weren't they redundant?) if they work - connect the green wire to any black and it should power on.
