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.
