New build -- no graphics keyboard or mouse

[melissalynne7]

I just put everything together and when I start it up all fans are working but I don't get anything on the monitor and there are no lights on the mouse or keyboard. I have unplugged everything but the basics. I don't get any beeps but I don't think I have onboard sound. I have tried reseating everything and I don't know what the problem could be. Any ideas?

My system:
MOBO: Asus M2n-SLI Deluxe
GRAPHICS: EVGA eGe-Force 9600 GT
PROCESSOR: AMD Athlon 64 X2
MEMORY: 2 2 GB A-Data DDR2 800
HARD DRIVE: 120 GB Seagate SATA

triple check all your motherboard connections. did you plug in the CPU power? if your PSU has a 20+4 pin main motherboard power connector, did you remember to plug in the +4? refer to the motherboard manual for correct wiring.

I don't get any beeps but I don't think I have onboard sound.

if you put it together you should know if you have onboard sound or not. if you are referring to the POST beeps, that sound does not come out of a sound card, it comes out of a little onboard speaker which should have come with your motherboard.

I've always found the most problematic part of the build is plugging in the leads from the front of the case that control the power button, reset button, and LED's on the front of the case.  Even though most manufacturers have gotten better with pictures, diagrams, and syntax (All Your Base Are Belong To Us!) it is still easy to plug those leads onto the wrong pins on the system board.

I have the 4 pin plugged in as well.  I have reseated all my wires including the lead from the case as suggested by Aegis.  Right now I have unhooked everything and am trying to clear the CMOS. 
I am thinking that the problem is either the memory or the motherboard.  I 2 sticks of A-data 2 GB 800 Ram.  I have tried using bother sticks separtely in different slots.  No beeps though.  My only other thought is that its the motherboard.  Is there any way for me to be sure the mobo is a dud?

[Aegis]

Pull both sticks of RAM, and start the computer without any RAM, and see if the system board reports a memory error or no memory.

All MBoard standoffs were used ? ?
Thermal compound applied correctly ? ?
New or used PSU ? ?

[Aegis]

Hey, Patio, excuse my ignorance -- I'm sure you're used to it by now -- but what are standoffs? 

"I am so smart -- s, m, r, t."   

[patio]

Small ferrules to be placed between the MBoard and case mounting...usually made of brass.

[Aegis]

Oh, yeah -- those thingies!  They are standoffs -- I can't even think of what I was calling them...

Whap, should have had a V8.  Check that your CPU is in the Socket an that its secure

I pulled both sticks of RAM and still no beep. 
A friend tested my power supply and it wasn't working properly (no 5V).  So we hooked up a working PS and still nothing.  He thinks the processor is bad because he said it isn't heating up at all.  We tested everything we could (graphics card, power supply, ram) but we didn't have another processor to test.  So its between the motherboard and the processor.  But I don't know which I should bet on?

[melissalynne7]

And the standoffs are correct and the processor is secure.

I've looked up reviews on both the processor and the motherboard.  Seems like no one has really had any problems with the processor.  This makes me think its the mobo.  But I'm wondering if starting the computer with a faulty power supply would have caused either of these to go bad???

[squall_01]

yes it is possible that the PSU could have ruined the board.  A possible overload.
