I bought a dq77kb mainboard and I cannot get to show information on a display.
Also the keyboard numlock led does not light up.
The processor is in the http://processormatch.intel.com/Processors/CompatibleProcessors?componentName=dq77kb compatible procs list
its a i3-3220T processor. The cpu fan start to run. I have a headset plugged in and I do not hear any beeps
When I remove the memory I hear the 3 beeps.
I can't go to the bios as I can see anything. It appears the usb ports don't get power.
I would try a bios upgrade if I could, but it doesn't get to that stage. So no POST either. Tried clear CMOS with power cable dettached, doesn't help
All of this has also been performed out of the chassis with only one memory card in place, no connections but the power switch. It starts running it gives no unusual led activity and no beeps.
The processor is compatible and I don't have any other processors.
The power is connected externally and it has 90 Watts. It boots up an hp laptop nicely with no issues.
I followed all the troubleshooting steps but don't know what else there is I can do.
I have seen multiple posts regarding similar issues. They have not been answered by Intel here:

Hello Mutepower, I am sorry to hear you are having problems with your motherboard; however I will be more than happy to assist you on this issue.
First of all, since you already test the system using minimum configuration and out of the chassis, I really think this is a problem related with the power supply or AC adapter you are using.
It is necessary to use a 19V DC power input connector, however it needs to have an output that at least 120W.
If the issue persisted, even trying a different power source, please get in touch with our Warranty Department so they can help you to replace the unit. Remember that the motherboard needs to be under warranty in order to be replaced. http://www.intel.com/p/en_US/support/contactsupport http://www.intel.com/p/en_US/support/contactsupport
These are some examples of compatible adapters that will work with this board.
Hi I went with your recomendations and bought this compatible adapter from the list
FSP180-ABAN1 180W 19VHowever it has a Plug 5.5mm/2.5mm plug whilst the dq77kb requires a 7.4x5.1mm one
Are there connector tips available to convert to required plug size?
I found the correct connector tip and had it delivered by the US Postal Service since I could not find then in the EU.
So I got 180 Watts to boot up this device and I still have the exact same issue. No beeps no post no video. The green led is on when connecting the power supply, I hear no beeps when I connect the headset and the cpu fan is spinning.
I don't hear a beep or something indicating that POST might be doing its checks. Als the Num Lock and mouse connected by cable are not lighting up.
Please give further instructions.
I got my motherboard back today with a label functional. The issue remains.
When I am getting no beeps and I'm using a recommended power adapter and a compatible CPU and the mainboard isn't going into a POST nor providing my keyboard with power, what could be the issue?
Could it be that my CPU despite being compatible causes this?
Since you already replaced the board, it has to be something else causing this behavior. can you test the system out of the chassis, or ALL in One?
Finally, if any of these steps resolve the problem, I'm afraid that it would be necessary to replace the processor.
I allready bought another adapter you recommended.
I tried using one memory stick
I tried clearing the CMOS.
I just got the board back and no feedback. I think the CPU might be the problem but I don't have other CPU's or mainboards lying around.
Now I had some time to try again I bought a new i3-3220T processor. The issue remains.
I even bought a displayport cable to give that a try but that doesn't help as the mainboard doesn't go into a POST or something.
I would very much like to know why the board was sent back to me without any details as to how they tested it as they said there was nothing wrong with it.
So far I contacted intel support Costa Rica and tried all the steps to recover a mainboard but nothing helped. I tried buying a recommended psu and that didn't help. I then sent it to Intel and they sent it back claiming it works fine. I need to know what they tested because it ain't working here at all.
I bought a new identical cpu and that didn't help either. So tell me what to do please. This seems like a good mainboard if it would work so I'm not going to throw it in the bin.
I understand your point Mutepower, and it is hard to say the reason why you are experiencing this behavior.
Are you using a regular chassis or is this an ALL in One system?
Could you send me some pictures from the system?
Would you please also send me a PM (private message) with the service ticket that was given to you? I would like to check some information.
Hi I sent you a pm with a picture, the link is
I no longer have the ticket number. I can't find an e-mail with the ticket number. A ticket was made with my address and serial number as can be seen on picture. If you need additional info let me know.
The screen is black and no POST performs however a signal is received by the display by the mainboard which I determined by coupling it to an HDMI switch however nothing is displayed the post just wont happen. No beeps greend led, see info above.
I sent you a reply PM 2nd of march pls reply
AA G81483 501
BIOS: -> impossible to provide, there is no post and consequently no access to bios
cpu is a compatible i3-3220T (bought a second one to be sure there was no issue with cpu)
It looks like the board comes with BIOS version 0051, could you please try to perform a BIOS update to version 0052 but following this procedure.
http://www.intel.com/support/motherboards/desktop/sb/CS-023360.htm Desktop Boards — Instructions for Recovery BIOS Update
Let me know the results.
I downloaded the BIOS Update [KBQ7710H.86]
file name: KB0056P.BIO
and copied it onto an empty usb msdos(fat16) stick
I removed the bios jumper to configure it for bios recovery.
I plugged in the USB stick and then turned power on
waited 20 minutes, powered it off, removed usb, set bios jumper back to normal.
I tried this procedure before with chat support but tried it again just to be helpful.
The mainboard led is green cpu spinning.
But again I get no display and the mainboard doesn't go into a POST or leds up a keyboard or mouse.
It doesn't boot to USB so it appears impossible to update the BIOS.
If I can send the mainboard back to Intel, please make sure they actually connect it to a display and go to the BIOS rather than just looking if the green led is burning and shipping back it is working.
Even though you are being helpful It has been a waste of time and resources so far for everyone involved.
Let me know how to proceed, thank you.
PS: trying with the 52 version (as per your request) produced the same negative result (the usb led doesn't indicate any activity either)
Requested assistance via intel customer support. I would appreciate if you adjusted some parameters where necessary to link it to previous rma if needed.
