Computer just beebs on start up and nothing on display.

Alttebest · Jan 22, 2017

So. Just to clear off my computer was working before. I went to CPU-Z program for no particular reason and noticed that under memory category It said that channel was single (I have 2x8).

I opened my computer's case and noted that rams were on slots 3 and 4. I watched from my motherboard's (asrock z87 pro3) manual that it should be on slots 1 and 3 for dual channel. So then i changed them. Turned on the pc and I got an error that only 1 ram were recognized. So I decided to change rams to 2 and 4 (since that works too for dual channel).

But then when I tried to start my computer it didn't start and instead got three beebs. Which indicates to memory error right? So then I changed my rams back to 1 and 3 and then I got four beebs. Which means system timer failure. I find this really weird. Then i tried with rams on 3 and 4 like they were but that didn't work anymore. I got 3 beebs.

After that I've tried disconnecting all unnecessary devices. Graphic card, all USB devices, screens, Lan wire, hdd etc. Only had psu, CPU, mobo, ssd and one ram. I got 4 beebs. I've tried rams from my old computer so I'm pretty certain they are not the problem.

Could it be possible that one of my motherboard's ram sockets are broken? It seems like since I get different beeb error when rams are in different socket. But maybe something else? CPU? Is there anything I can do? I would rather not buy new mobo but it seems like it's the only option.

Full system specs.

Gtx 980ti
I7-4790k
Asrock z87 pro3
Corsair CX 750 (pretty new probably not the problem)
Kingston 2x8gb 1600
Kingston Ssd and seagate regular hdd

Clear the CMOS first, using one stick RAM, boot into the BIOS and set up the XMP profile in the memory section, save and exit. Shutdown the PC, install other RAM and reboot the PC.

I've cleared the cmos by jumper and by removing battery with no success. I also tried only one ram to each one of the slots and slots 1 and 2 give 3 beebs and slots 3 and 4 give 4 beebs. Ram ain't the problem I just tried my ram to another computer and it worked. And the problem is that I can't access my bios since there is no display.

And try take all the RAM, SSD, gtx980ti out, clear the CMOS again. Boot the pc without RAM, hard driver, using onboard iGPU, usually if the PC will boot but you will get no RAM no boot device error. If the PC will not boot either, so either the MB or CPU has problem.

I didn't have any unneeded devices when i cleared it. With only mobo and CPU I get three beebs (which I think is right since I got no ram) and with one stick of ram 3 or 4 beebs depending on what slot it's in. I think (hope at least) that it's not CPU problem since i get different error depending on mobo's ram slots. Maybe my motherboard's ram slots are broken or it's broken inside somehow? I can't figure any scenario that I get different error if my CPU Is broken. I'm not sure though since elseway i wouldn't be here asking right?

3 beeps = no RAM error.
4 beeps= system timer. http://www.asrock.com/support/faq.asp?k=beep+code

If you can boot up the PC with one stick RAM, may try update the chipset driver, which comes with the memory controller driver, hope the memory slot does not have the right driver. Chipset driver https://downloadcenter.intel.com/download/20775
For the system timer, check and change it.

I can't access my computer's bios or Windows. I get nothing on display. So i can't update any drivers. Or is there any other way of updating drivers i'm not familiar with? Same with the system timer.

With only mobo and CPU I get three beebs (which I think is right since I got no ram) and with one stick of ram 3 or 4 beebs depending on what slot it's in.

You need try other RAM, whatever you get from your friend or buy other one. Don't know what happens during you reseat the RAM. The RAM may have problem.

As i said in my first post i tried different ram with same results and also tried my ram to other computer and it worked. I seat the ram just normally by pressing the ram straight down with decent amount of force so that it clicks on both sides. I've now ordered new mobo so i can test my CPU in it and see if it's mobo or CPU problem. I really hope it's not CPU problem and when I try my CPU to new mobo it just brakes it. Is that even possible in modern components?
