I just put this computer together yesterday, and I finally had to go to bed last night. The computer only boots when it the clear cmos jumper is set to clear. This is really strange. I have tried to isolate the problem:

I am running the motherboard on the box it came in. I have it plugged in to the power. I have the keyboard plugged in, and I have the monitor plugged in. That is ALL.

What I mean by 'it doesn't boot' is the cpu fan doesn't start, and it makes a wierd sound instead. Also, no lights are on, no beeps, which the manual says is a Abnormal: CPU / Chipset error.

Edit: now that I breadboarded it, all the debug lights are on, so it SHOULD be fine. but the cpu fan isn't spinning and it won't output graphics, so no go still...

P.S. In case you need my specs, here they are:

PSU ANTEC|EA750 750W RT

VGA MSI|R5450-MD1GH/D2 HD5450 RTL

MB BIOSTAR | TA890GXB HD R 1

DVD BRN ASUS | DRW-24B1ST/BLK/B/AS%

HD 500G|SEAGATE ST3500418AS

MEM 2Gx2|CORSAIR CMX4GX3M2A1600C9

CPU AMD|PH II X6 1075T 3.0G AM3 RT

The problem was the Motherboard Manual. I emailed biostar and they told me to look closely for numbers. There was a one and a three, turns out the CMOS jumper in the manual was flipped upside down compared to the jumper on the motherboard.

This screams corrupted BIOS to me...I would look at booting it with the bios set to clear and flashing or returning as DOA

edit: flashing up to current bios might do something for you...another option I hadn't thought of is making sure your power and clock settings are appropriate in the bios. not having appropriate values there can give you some really weird problems

ram sometimes fails when underclocked...not all the time, but sometimes. i would look in to properly matching components before i started getting overly concerned about DOA. there is voltage tuning that can happen also, but that's way outside of basic help...just so you know, reports indicate that the processor you are using overclocks okay up to 4.4GHz with the right voltage settings. biostar.com.tw/app/en/mb/introduction.php?S_ID=478 indicates that 1600 is only supported overclocked. get it working stock with supported components

If I boot it with the jumper set to clear bios, then it WILL boot, I even installed windows. BUT whenever it restarts, it trys to install windows. I had to fiddle with it and it restarted 3+ times while installing it. So is the only thing I can do is return it as DOA? –  Caleb Jares Dec 13 '10 at 10:16

+1, everyone forgets this little bit of knowledge. You should add it to your answer. –  Moab Dec 13 '10 at 16:29
    
@Moab I moved it up –  hbdgaf Dec 13 '10 at 20:33

Maybe you mis-interpreted the jumper diagram, and you got it backwards? Grabbing at straws here.... –  Moab Dec 14 '10 at 3:01
