I'm just going to post some stuff, and you see what you may think may help.
1.I hope you observed the anti-static guidelines, or you have silently toasted your delicate computer components. Static will silently fry them out. You won't see it or feel it.
(Reseated CPU? Static will fry that thing out F-A-S-T! Didn't clean the top of the CPU, and the bottom of the heatsink, and apply new thermal paste? CPU is fried. Takes about 10 minutes or so for an Intel. Takes about 20 to 30 seconds for an AMD!)
2.Floppy drive has no power? It attaches straight to the PSU. Either it is bad, or the PSU. Even if you swapped PSU's, it doesn't mean the one you installed is good.
If the PSU has a weak voltage rail, it won't give enough wattage to the processor.
A.ALL the lights use less than 1 watt.
B.EACH fan uses 2 to 3 Watts.
C.A harddrive sitting there spinning, because there is no processor to tell it what to do, uses about 2 to 3 Watts. (Read on)
D.When BIOS tries to turn the processor on, it can't. Why? Because processors use anywhere from 55 watts to 125 watts. Depends on the processor. If the PSU has a weak voltage rail, the processor won't turn on.
