No Posting- Bad Mother board?

[notantisocial]

I am having a problem where there is no post, but I don't have a green light on my MB to show it has power. The power supply came with my barebones system and I was using it in another computer for a short while before putting it back in the barebones. The MB doesnt beep and the monitor never recieves a signal. Neither usb mice or serial( analog?) seem to receive power.

Can the MB post with bad ram and/ or bad cpu?
I have all brand new components: corsair 240pin ddr2 ram and the processor is an AMD X2, when we pulled out the processer there was plenty of heatsink paste and no bent pins (I installed it orginally).

I am sending the barebones back to new egg and they say they will send it back to me if it is found to be not defective. I am pretty sure that the motherboard has a bad component specifically the VGA/ video output. Does this sound reasonable?

It sounds more reasonable that the power supply that came with the case is not up to spec for that motherboard, if it's an AM2 motherboard it requires a 24 pin main connector ATX 2.0 spec unit. You also must connect the 4 pin aux to the motherboard.

Can you please post the brands and models of the components?

Sure, I can do better as newegg still has the product for sale.

Here is the processor I bought. http://www.newegg.com/Product/Produc...82E16819103759

I did connect the auxilary 4 pin power supply and all the case fans started up as well.

No good - that PSU is only 250 watts and is not ATX 2.0. It is barely enough to drive the onboard video and it definitely cannot handle a video card.

I have a 650 watt aftermarket power supply but it wouldnt fit in the case very well -- there was no clear place to mount the harddrivee. Newegg says they'll refund me for the case, should I take the refund and pick up something else?

I don't current have a different videocard... mine wouldn't fit-- its older.

Also if there was not enough wattage to run the motherboard would it run at all or just shut down?

Any particular reason you are using such a small case?
