What did I break

[josiahlalala]

So I stupidly plugged my chasis fans into bother the motherboard and a molex power supply. I thought that plugging the fans into the motherboard allowed the bios to control the speed and that in addition I needed to power the fans by plugging them into the power supply. Did I likely fry my motherboard or CPU. When I turn on the computer the CPU fan spins as well as the graphics card fan, however I am not getting any picture or boot. I have an ASUS motherboard and it is simply displaying the code 00.

I need to ask first. How did you plug a fan with a single plug into two power sources at the same time? That may give us a clue on whether you broke something or your boot issue is due to something else, which it may well be given what you just did.

The fans have two plugs one for the motherboard and a plug for a molex.

Oh ok. No in that case you didn't break anything by double-plugging the fans - at most you damaged the fans, but I doubt even that. It's something else that is preventing boot-up. Did you plug the CPU fan and the CPU auxiliary power connectors? That's a pretty basic oversight.

All the fans spin when I power it up, but I'm not getting any picture or boot up even to the BIOS. I also smelled a faint electrical burn smell before I realized the error.

Remove everything - RAM, case fans, graphics cards, hard drives and optical rives. Leave only the CPU (with it's heatsink/fan) on the mobo. and connected to the PSU.

Usually on newer boards there's a power-on button on the board. If you rpress that, do any ligts onthe baord come on? Do you have a diagnostic LED on the mobo? any numbers there? Any beeps? Did you get a little speaker in the mobo or CPU package? You may have to connect that for beeps.

Make sure the 24-pin connector is seated correctly and tight. Make sure the CPU power is connected and the CPU fan is plugged in to the motherboard.
