It won't boot. I'm fairly certain power is somehow getting to the MoBo, but it's not being used correctly. Here's my evidence:
If my PSU isn't plugged into my mobo or any of my peripherals, it does nothing when I plug it in. However, if I plug it into my mobo, it repeatedly makes a periodic faint clicking noise, and is clearly using power, as my lights flicker when I do so. Which probably isn't a wonderful sign.
When I hit the power switch on the front panel, nothing happens. The power LED does not go on at all. The PSU fan, CPU fan, and system fan all stay dormant and do not turn on at all. Nothing happens if I "jump" the mobo by closing the circuit between the two leads to the power switch on the front panel with a screwdriver, either.
This is with the PSU I bought. I also tried to put in an older atx psu that i know functions, and got a faint high-pitched ringing noise (which "sirened" downwards after I turned power off) when I plugged into the AC outlet.
This IS my first system, so there's probably some blatant compatibility issue I'm missing here. Does anyone know where the problem could lie? I'd be eternally thankful. Here's what I'm using:
PSU: ATX12V, 400W, Output +3.3V@25A, +5V@32A, +12V@19A, -12V@0.8A, +5VSB@2.0A :
CPU:Athlon XP 2600+, FSB 333MHz, Voltage 1.65V
MoBo: GIGABYTE GA-7VT600P-RZ, CPU Type Athlon XP, FSB 400/333MHz, Form Factor ATX
I'm guessing the problem is with the interface between two of these three things. Any guesses?
