No Beep, No Post, No Display

Jedisponge · Oct 10, 2013

I realize that there are about a million posts on this forum on this topic, and I've gone through the majority of them, but nothing seems to help. Here's my situation:

This is my first PC build, and of course things have gone pretty badly. I installed all my components, triple checked the connections, and yet, when I turn on the system, I get no post beep, and no display on the monitor.

After a week or so of research, I've tried everything I could find. The first thing to yield results was to take out the RAM and put it in one stick at a time. With one of my sticks of RAM, I got 3 beeps after turning on the system, but still no display. After taking out that stick and putting in my other one, I got NO beeps and still no display. After that, I placed the other stick that DID get the beeps back in by itself, but it didn't get any beeps that time.

On another attempt to fix the computer, I found this video and followed what it said. It basically tells you to take out the CMOS battery and one by one take out each component on the motherboard, boot, and see if you get any beeps. When I would flip the power switch on the back of the power supply, the system would automatically turn on without me pushing the power button, and the system fan would not run. I assume that this was because there was no CMOS battery, because when I put in back in, it functioned as it was before. Anyway, with the battery out, the only time I got a beep was when I had the graphics card and both RAM sticks out. I got 3 beeps again. After placing all the components back into the computer and putting the CMOS battery back in, I still didn't get any beeps, and still didn't get any display. I talked to the maker of the video, and he says that it could possibly be my RAM.

I've gone through the checklist, I've tried everything I can, and now I'm desperate. I need your help and advice, what should I do? Is my motherboard fried? Is my RAM garbage? What's wrong?

use the force young one!!!! use the force!!!! hahahaha
look on the edge of the motherboard there should be a four or eight pin power plug. make sure you have your powr supply plugged into the pci power plug. the motherboard itself should not be screwed down to the case mb tray there should be some brass standoffs under it. look to see if the io shield that covers the back of the case if any of the fingers fell into the usb or ethernet ports or shorting the back of the mb. same goes for the cpu cooler if it has a back plate check that it not grounding out or shorting the mb.

The motherboard manual will have the beep codes listed and will tell you what the issue is. I would verify that you properly seated your cpu into the socket and clamp locks are down. make sure that you align the triangle with the triangle on the processor socket. and if possible get another power supply to test your system with .. also make sure you have the 8 pin connector if required plugged into the motherboard. and not just the main 20 + 4 .

sounds like dead ram to me. corsair has great customer service. return it and get new.

Jedisponge · Oct 10, 2013

I have already verified all of this. CPU installed properly, triangle lined up, standoffs installed. Everything should be good to go. Something is faulty and I don't know what. Also, my motherboard manual doesn't have any beep codes in it...

Jedisponge :

A positive attitude might have helped

Really, expecting disaster, even with your first build, is not a good plan.

You haven't stated specifically that you have followed THIS checklist:
http://www.tomshardware.com/forum/261145-31-perform-steps-posting-boot-video-problems
But that's probably what you meant.
That is there because it really does help with 90% of new build issues. Sometimes people skimp on the steps.
It would be good if you could be a bit more clear on what is actually happening. "No display" and "No beep" are descriptive, but what else is happening?

Does the CPU fan spin up and stay spinning until you turn off the system? By system fan do you mean CPU fan?
The system fan is mounted in the chassis and is there to cool the entire system.

You say the system would power on ...

"When I would flip the power switch on the back of the power supply, the system would automatically turn on without me pushing the power button, and the system fan would not run."

How do you know that the system is turning on when you have no CPU fan spinning? What exactly are you seeing?

Jedisponge · Oct 11, 2013

By turning on I meant that all the fans in the system are spinning. The system fan (the one mounted in the chassis) is spinning, the fan on the graphics card is spinning, and the heatsink fan is spinning, as well as the LED on the power button. The only time the system fan didn't spin was when I had the CMOS battery out. All the fans continue to spin until I push the power button. I do not have to hold it in, I just have to tap it.

And I wasn't expecting disaster, it just happened...

smorizio · Oct 11, 2013

look at the cmos chip on the motherboard. look at the rev sticker to see what rev the cmos bios is at. if it to low the motherboard wont post.

Proximon · Oct 12, 2013

smorizio :

I considered that as well, except on the CPU compatibility list for that board I saw that the original BIOS was tested and worked with that CPU... but of course this could be a slightly different CPU with different stepping. I didn't check it that closely.

Jedisponge · Oct 12, 2013

So do you think I should just send back the RAM and get it replaced? Or should I return it and get a different brand? Because most of the people I've talked to have said it sounds like a problem with the RAM.

Proximon · Oct 13, 2013

I think it could be RAM, CPU, or MB. There is no way of knowing without swapping parts out for known good ones.

Jedisponge · Oct 13, 2013

Proximon :

I packed up the RAM and I'm gonna get that replaced.

Jedisponge · Oct 22, 2013

After getting replacement RAM, CPU, and motherboard, the computer will still not post. I'm desperate here. Do you have any other ideas??

Proximon · Oct 22, 2013

If the PSU was never sending a power_ready signal you would fail to POST.... but I would expect the PSU fan to spin.

You have done the full checklist?
http://www.tomshardware.com/forum/261145-31-perform-steps-posting-boot-video-problems

Your symptoms do point towards the most obvious answer, given by the first two responders.

Again though, there is nothing to indicate the system is not POSTING.... only that there is no display.

Is the display cable attached to the 7770? It would not work if attached to the motherboard.

Proximon · Oct 22, 2013

Two guys with the same issue:

http://www.tomshardware.com/answers/id-1842389/post-beep-display-unsolvable-issue.html

I wonder.... could your MB be defaulting to onboard display? Do this particular BIOS require manual setting to use a discrete GPU?

Jedisponge · Nov 10, 2013

Sorry for kind of forgetting this thread guys. I got it fixed. My CPU is very sensitive and was just not quite seated correctly. Thanks for all the help!

Proximon · Nov 12, 2013

OK Thanks for coming back.

jethro8035 · Jan 20, 2014

No post, fans run, no monitor. Solved!!
I can't believe just how many people have had this problem looking through posts:
My desktop symptoms were exactly as most others with the problem of no post, fans running and no monitor;

Background: I decided to flash my BIOS from version 7 to version 10 and to replace the Sempron CPU with an Athlon dual core by way of a basic upgrade. Then install a graphics card.

Flashed and replacement CPU fitted. Now we have the symptoms!

I tried pretty much everything by replacing the original CPU, checking fittings on motherboard, checking monitor, checking RAM by removing etc.. etc...

I was in the process of looking to replace the MOBO then discovered that an upgraded PSU would cost only £12.

Fitted new PSU, job done! Fixed!!!!
