Help with BTX Motherboard

[illmatic1]

I currently bought a new case for my brother's computer. I tore the parts from the old case and stuck it in the new. Unfortuately it was a sony and had a BTX motherboard. I plugged everything up (i think) and when I power it up, it beeps (1 long followed by 2 short).

Then, something shows up on the screen. Its that thing that thing that shows whats working when booting up the pc. And it stays at that. Everything seems to be working fine but it says the power and the chasis fan is "abnormal".

I am given two options.
- Press [F1] to continue
*when I do that, a cursor comes on the screen and flashes for a few seconds, and then the message "Reboot and select proper boot device".

- Press [F2] to enter Setup
*when I do that, I get into the BIOS setup. I look at the fans and it shows how fast the cpu fan is spinning but it says "n/a" for the chasis and power fan. But those two fans ARE spinning.

I also have an AMI BIOS.

Also, I currently have the chasis fan connected to the psu using the molar connecters. Before I had the chasis fan connected to the motherboard with this. There was also something like this coming out of the old psu that I had in the case. The new PSU doesn't have this.

just get a case fan with that connector, and turn off the sensor in the bios for the ps fan. also, its molex, not molar. o, when u get a fan, make sure it has 3 wires, or otherwize that ull still get error

How exactly do I disable the sensors?

Do I change the "n/a" to "disabled" ?

 

[bmxfreakrider]

if u can, then yes

Okay, I've disabled the sensors. Now when I boot, I see the cursor blink for a few seconds and thn I get the message.

"Reboot and select proper boot device, or insert boot media in selected boot device and press any key"

Do I need to have my CD and DVD drives plugged in? I only need the hard drive plugged in, in order to boot, right?

 

[illmatic1]

The hard drive is set as the Primary Master. I also pressed [F10] during start up to enter the boot menu. I selected the hard drive but still got the same message.

 

[bmxfreakrider]

do u have an operating system installed?

 

[illmatic1]

Yes I do.

hmm....remove the cd drives, and anything ide, except for the hdd, and try a different cable for that hdd. also try reseating the ram, and the cpu.

hold on, wait, before that, do u got ur xp disk or whatever? if so boot with that and see if it finds the os on the hdd. if not, then u just gotta reindstall
