Faulty motherboard?

I'm building a new computer for a relative for Christmas. Everything is connected properly, but when I power it on, everything turns on, but it doesn't post or boot. I've swapped the PSU, RAM, unhooked optical drives, unhooked HDD and put in Linux disk. I assume the only thing left is the motherboard, right? I could really use the help ASAP since I need this done this weekend. Thanks!

did you put the memory in the right slot as mark in the board user manual all the power cable are plug on the board and you put the standoff post between the case and the board ?

I think it's the motherboard but I am new to this stuff. When you say everything turns on do you mean the optical drives? Your PSU sounds functional if the optical drives turn on. There should be a beeping if you ram isn't installed correctly. You should hear beeping if it's something other than your PSU or Motherboard. I think your PSU is good so that leaves the motherboard. Before I say it's you motherboard I need to know if you Motherboard has a buzzer on it because apparently they don't all come with them. If you do have a buzzer I think it's your motherboard.

yes, the optical drives lit up, along with all fans. from what i've read, the motherboard (biostar G41D3) is supposed to beep.

i'm 99% sure the power button is hooked up correctly.

Hi, Can you detail the components (CPU, power supply. graphics card, memory)?

Yes, it has HD Audio and AC 97 coming from the case. I've tried them both.

I think you would hear beeping if it was the CPU. I'm not sure what BIOS you have but you can look up the beep messages and everything that it beeps for you can eliminate.

Can you post a picture with the board so that the speaker, 24 and 4 pin power connections can be seen?
If starting the board with only CPU and CPU fan installed are you getting any beep? Is the CPU fan spinning?
I suggest testing the board outside the case, on the board's box.

Still no beep with only the CPU and CPU fan installed. Yes, the fan is spinning. What is the purpose of testing outside the case? I haven't done that, but I did read it somewhere else, as well.

For ruling out a shorting issue (an extra standoff for example can short the board).
The connections seem OK. If still no go outside the case, I suggest reinstalling the CPU. Are the board and the CPU new or used?

OKay, so I tried it outside the case. Still no post. Unfortunately, I don't have any thermal paste so I'm guessing reinstalling the CPU wouldn't be the best idea until I get some, right?

The board and CPU are both used. The mobo was "like-new" from Amazon Warehouse and the CPU was supposedly tested as working on a eBay from a power seller.

The best way in my opinion would be to have them tested at a local shop. Or, if you have a spare board that supports the CPU... This way you'll know if it's a board or a CPU issue.
And yes, you'll need thermal paste for reinstalling the CPU (you have to clean the old one and reapply).

Going to a local shop would defeat the purpose of this super budget build.... Amazon is paying for my return shipping. I ordered a new mobo. I explained the the seller my situation and he said I could return the CPU if it turns out to be the problem... so it should all work out.. with the exception of having it done on time =/
