Help! Motherboard problems... ASUS P5K PRO

Dear readers,

I am in desperate need of assitance/advice. First I will attempt to explain my situation:

I ordered the following computer components from a local vendor:

Intel Core 2 Quad Q6600
Zalman CNPS9700 NT

Cooler Master Mystique 631
Corsair CMPSU-620HXEU 620W
Asus P5K Pro
Kingston HyperX 1GB 1033MHz PC2-8500 (4 of them)
Samsung SpinPoint T166 HD501LJ 16MB 500GB x2
Samsung SH-S203 SATA

Gainward GeForce 8800GT 512MB GS
Samsung SyncMaster 245B

Anyway, the vendor wrongly sent me a ASUS P5K instead of the ASUS P5K PRO motherboard. I did not notice this AFTER I had

installed all the components. The computer ran just fine and I had no trouble with this set of components.

However, I discovered that the ASUS P5K does not have two internal RAID controllers so therefore I wanted to get the

correct board from the Vendor. The vendor then sent me the correct ASUS P5K PRO motherboard.

I then installed it with the same components that I had been using with the ASUS P5K (without problems) but when I powered on my computer nothing really happened. The GREED LED light on the motherboard came online and the instant I pressed the POWER ON button the fans (CPU and CHASSI) appeard to begin running for about a split second and then just died off. Everything just appeard to be dead. I removed all components from the motherboard except the CPU/FAN and one stick of memory but there was no difference. (Tried everything I could think of with all kinds of hardware combinations).

So... I then started to wonder if I had somehow damanged some of my components and reinstalled the ASUS P5K (without the PRO) and now everything worked fine! So I assumed the ASUS P5K PRO motherboard was defect and sent it back to the vendor.

I now today recieved a new ASUS P5K PRO motherboard and after spending over one hour installing it I'm now experiencing the EXACT same problems!

I'm baffled as to what could be the source of the problem. What are the chances I've received TWO defect ASUS P5K PRO motherboards in a row?

I started to wonder if the ASUS P5K PRO motherboard did not support my memory stick. However, after consulting the manual it describes EXACTLY the same as the ASUS P5K motherboard manual, so I don't understand how this can be related.

Does anyone have any tips or suggestions I can try out to troubleshoot my problem?

Thanks a lot for reading! Please help me!

Regards,

Someone on another forum found the answer for me:

Hi,

I can't see any obvious reasons as to why it shouldn't work (you probably would have spotted it if it were obvious).

The thing that pops into my head is some kind of unintentionally short circuit. So I would check the screws (holding the MB to the backboard), making sure they don't accidentally touch something that they are not supposed to touch.

Taking the whole setup out of the chassis/tower and rebuild it stripped on a non-conducting surface is a normal (my way atleast) way to check a system if all else fails. That way if it boots I know it has something to do with the chassis/connection/short-circuit there. If it doesn't and since all the components works with the other MB that seems to indicate that you might have received a faulty MB (again).

Short summary:
Strip it down and retry outside the cabinet with only 'mandatory' components. Add on untill it fails or succeeds. If success try it in the chassis again. If it then fails: Locate the short circuit.

It was a short-circuit problem. I had forgottent to remove one of the supporting bolts when using the P5K motherboard (the PRO model is significantly smaller).... 🙁
