Computer won't post

[bobdaman18]

Hello,

My computer was on while I was in another room. I came back in to see a blue screen up. I didn't check what it said. I turned it off. When i tried to turn it back on it started up for 5 to 10 seconds and then restarted. It then stays on but doesn't post.

I have tried:
checking the connections of all the wires
unplugging all non essentials
replacing the motherboard
replacing the power supply
using only 1 stick of ram

What should I try next? I was thinking maybe a new video card? Any thoughts on the problem would be helpful.

Try resetting the CMOS. Some of the newer motherboards have a button for this; Some will still have jumpers.

Thanks for the reply. I'm going to come clean, I tried resetting the CMOS and it still didn't work. Then i went through the troubleshoot checklist here:

With one stick of ram in the system now starts up. I tried it before but I must have not seated the ram properly or something when I was testing each stick. I guess it's just a lesson to really put the effort into the troubleshoot guide. I could have saved myself a lot of headaches.

Alright, I guess I celebrated too early. Both sticks of ram work but only in the DIMM_B side (the one closer to the front of the case.) It'll start up with 1 stick of either ram in either slot or both sticks in the b side, but if I stick either stick in the DIMM_A side it won't boot. Any ideas?

Not sure, do you know what your motherboard make and model is?
Are both sticks of ram exactly the same?

 

[bobdaman18]

Yeah, its a p8p67 motherboard. The ram sticks are both the same ripjaw x:

What kind of performance hit are we talking about if i don't do the dual channel thing and just leave it as is?

is that the Asus mb? http://www.newegg.com/Product/Product.aspx?Item=N82E16813131918

Mmm, close. I think it's this one: http://www.amazon.com/P8P67-REV-3-0-Supported-Motherboard/dp/B004QF0VEA/ref=sr_1_2?ie=UTF8&qid=1359870468&sr=8-2&keywords=p8p67

I think the pro might be a nicer version of it. But yeah, its one of the asus launch motherboards for sandy bridge.
