Hello, I have been building a new computer for school and I finished it today. First of all I have done all my research well and researched how to install everything properly.

I am using an Antec 1200 Case with a 650 Corsair Power Supply. The Motherboard is an Asus M4A79T Deluxe and an AMD Phenom ii x4 955 Processor and an Ati Radeon HD 5570 Graphics Card

I have installed everything and I have plugged everything up to start it up for the first time. It powers on and all the fans run, but when I plug it into the monitor it will say no signal and turn off.

I have tried different methods of plugging in the monitor....DVI and HDMI, but i do not have a VGA port. I have made sure all the connections are secure with no bios.

Can someone please help me I need this computer up and running for school I am a 3D drafter.

Thank you for your help

I have performed a bench test and it still does not boot with only one stick of ram and the power hooked up and the video card. I believe I have a bad motherboard, or bad ram, or processor but do not know which

Hi adanniels :) sorry to hear you are having this issue.
Does the MB have a built in speaker or have you got a case speaker?
If you have try connecting it and removing the Ram to see if you
get any error beeps, also double check the 8 pin 12v atx plug is
pushed firmly in the connector, have you checked the monitor lead
is in good condition and that it has no bent pins.
Is your MB the model that has a re-set and power on/off button on
it and if so have you checked them out.

I have checked all the connections and all the cables are in good working order and no bent pins. The motherboard does have power and reset switches but I do not think it has a built in speaker and I don't have a case speaker. I have been doing research online and found out asus is bad about flashing their motherboards with up to date bios. I am thinking about buying a new motherboard....not asus. I was thinking msi equivalent. Any suggestions phillpower2?

Your MB has all the bells and whistles but no speaker, not helpful.
You have done a lot of testing yourself so what I can suggest is
pretty limited but here goes, try removing the silver CR2032 MB
battery for a few moments and then replace it, this will restore the
MBs default settings, have you tried the video card in all slots and
is the card known to be working, and finally remove all the Ram and
see if that makes any difference, it will not POST I know but it may
produce an error of some sort, if you have no luck with the above I
would consider a bad MB 1st and a bad CPU 2nd, in any event if you
can return them both.
Below is an option for you to look at, you will notice that I picked
an option with onboard video so you have back up video should you ever
require/need it such as situations such as this;

Good luck and let us know how it goes.

EDIT: Link replaced.

Actually the motherboard you recommended does not have onboard graphics. Before you recommended this one I was thinking msi nf980-g65. I have already pulled the battery a few days ago and replaced and tried every possible posistion for the video card and ram. I am pretty sure it's the motherboard. What's bad is I no longer have the box for it. Stupid me. But if I get the new mb and it still doesn't work that means it's the processor

Sorry about that it was the wrong link so I have replaced it via an edit.
The fact the other one does not have onboard vga was why I chose the one
above and as luck would have it you have looked at the same one, the only
other one that I thought was worth a mention was this one http://www.newegg.co...N82E16813130269

But if I get the new mb and it still doesn't work that means it's the processor

Can you not contact the store and explain your predicament, you have no way of knowing
if it is the MB or the CPU and it should be up to the store to do the testing have you
kept your invoice and did you purchase both items from the same store?

Well I am the online shopper they were all bought from amazon.com and with no box there is no way to send it back. Stupid me...when I wired the case up (before I gained all this new knowledge) I thought okay the lights come on and the fans run I'm good and when I cleaned my room out I threw the boxes away :) that was hard lesson learned. So the best way I found to fix this mess was to order a new motherboard...and keep the boxes. And if it didn't work then it would be the processor. Cuz I made sure that it would definilty indeed have the bios for phenom ii x4 on it. Oh I also looked at the other motherboard you mentioned and only problem I had with it was it was a micro atx

Ok thanks for letting us know what you have decided and I hope you have better
luck this time around and please let us know how you get on.
Will Amazon not let you return the MB in other packaging if it turns out that
it is bad! after all you purchased the MB to install in your computer not keep
it in the box!!

Well to my understanding I have to have all the original packaging, and everything that came in the box. the Motherboard got here today and I will test it tonight to see if it works

UPDATE: well phillpower2 it is doing the same exact thing as the asus motherboard. lights come on, fans run, no video and no beeps. i was 100% to do everything perfect. Some would think of it as a waste of time but with the onboard graphics i knocked out the graphics card. so it is either the ram or the processor. but with no beeps that makes me believe its the processor. could a falty processor make the bios not beep?

Congratulations on resolving the issue and thanks for sharing the solution :)
It just leaves you with the problem of the surplus MB now, dare you take out
the CPU again and try it in the original MB?

I would leave well alone. If you could borrow another cpu, and the board works, you might try selling it.
