Well, it sounds like you have incompatible memory, but we need to look further to be sure. I suggest you try to borrow some memory that *is* on the verified compatible list and see whether you can get the board working then...
Hi N.Scott.Pearson, thanks for contacting back.
I have indeed tried RAM from the compatible list to no avail too.
However after giving up and deciding to rebuild my old rig back up I found that I have the same problem, and this is a set up that was running no longer than a week ago.
It cuts off when its in the bios also when loading windows. I am pretty sure it is my Modular Corsair 500w PSU. which shouldn't be playing up only being a year old, therefore I am going to get a new one today and see if I can claim on the warranty for the current PSU. I will keep you posted if PSU resolves the issue.
Makes sense that that could be the reason because: On DX79SI board I have tried every combination, different RAM, different GPU, not GPU, no RAM, no CPU. all of which still allow the board to switch on. However when everything is in, I am thinking that maybe when it switches on and then tries to take the surge from the PSU for the boot process that's when the PSU cuts out which makes it appear as a dead board.....
Thank you for joining the Intel communities.
I’m sorry for the issue you have and if you’re sure that this issue is caused by the power supply it will be very much appreciated if you could let us know how it goes after the replacement.
Thanks for your response. I
have now tested everything including a new more powerful corsair PSU of 750w.
I have now discovered that there is a light that flashes red at switch on/start up. This light means that there is a problem with the CPU, having tried a new CPU we have found it still does the same thing. Upon inspecting the pins and finding NONE of them are bent, in the wrong place etc.. The only thing It can be is a corrupt bios or a faulty board/socket.
So I will now most likely have to contact an Intel Service centre to find out if I can send it to them for analysis. I know that both CPU's work as I have run them in other pc's. The bios version that came with my board is the right version to recognise the i7 3820 CPU.
So after literally trying everything, from new RAM, to a new PSU, to a new CPU to a new heatsink and even GPU. It still fails to work, another key to knowing that it is a bios/board fault is that it will run up better when there is NO CPU in the socket. A pc will switch on but obviously you won't get to a bios etc without a CPU but it's a way of finding issues.
any suggestions Ivan?
Try removing the battery from your motherboard and every component you have installed for at least half to 45 minutes and then just put the minimum configuration back one.
After that is done, try to do a BIOS recovery you can download the latest bios version here:
Thanks again for replying. but how can I do a bios recovery when the board wont POST? I don't get any display on my screen, or will I now get a display because I have removed the battery for a while like you advised?
I have looked through the instructions you gave me thanks, very helpful however it shows an imagine showing what the bios update is doing, that surely wont show if I have never had an image shown by this board before will it?
you will need to see when the BIOS is updating and when the update is completed but if you don’t see anything on the screen you can still do it and wait for over 5 minutes to see if the BIOS recovery occurs, you will see the thumb drive flashing.
If that does not help at all to me this is a defective motherboard and you can submit a web ticket to get a warranty replacement for the unit at the following link:
I have now tried doing the BIOS restart. it appears that the USB Flash Drive doesn't even get used because it did not flash.
The computer just kept running until I switched it off, 6 minutes after initialisation. Since then I have replaced the jumper, removed the USB and tried starting it up, still does not post to BIOS and continues to do what it has always done right from the very beginning. At a loss for anything else to try.
Should I contact support and open a ticket then for warranty now?
Thanks for all your help thus far.
Me again, just wanting to check. This board was made in 2012 and never opened until I received it, Will there still be warranty covering this product?
Intel provides three years warranty from the moment you make the purchase, if you think the motherboard is out of warranty right now then I recommend providing the proof of purchase for them to approve the warranty.
I have been in contact with the Intel warranty support service.
Someone called Andre B is dealing with it, he has advised me that I can only claim after having the board for over 30 days from purchase.
Also he advised me that they no longer provide support via email, chat or by phone.
I have provided all information as requested but I get the impression that he doesn't want to help me.
I am confused about the part how I can only claim after 30days of purchase, who in their right minds would keep a faulty product for 30days if they knew there is a problem and need it replaced urgently?
Thanks for all YOUR assistance Ivan, I have found all your advice most helpful.
Could you please provide me with the service ticket number you got when contacted warranty support?
