There is no special setting, jumper or connection to use when boot, just by using the power jumper correctly the system should work fine.
These are our recommendations for this issue:
- Test the system out of the chassis, minimal configuration please.
- Let us know the part number for memory and power supply tested.
- Swap components to narrow the issue (power supply, processor) if possible.
dan_intel i have a similar (same) problem:
- tried one cpu intel pentium g620 (compatible with bios version 0018)
- tried with different ram modules
- used the external power connector
the used components worked well for another dq77kb board!
if i power up the board with cpu but without ram modules, i also get 3 beeps. if i power up the board with cpu and ram modules i get nothing.
do you have any other suggestions?

My board finally booted after installing a Core I3 CPU. Just for a test, I put my G440 back in, and again the board wouldn't boot. So, I believe, the CPU compatibility list for this board on BIOS 0018 is not accurate. With the Core CPU back in the socket, I updated the BIOS to 0048 and now all my CPUs work. Hope this helps.
There's definitely an issue regarding the hdmi video output on the DQ77KB. The first DQ77KB board that I had was experiencing video problems. I ended up with a bad bios flash and had to use the Intel warranty to get a replacement. The replacement board I received was a refurbished board and I had to fork out $25.00 for the shipping.
Anyways, I'm using the refurbished board and have been experiencing the same video problems as the first one I had. I'm connected via the boards hdmi port to my monitors hdmi port. Sometimes I get video and sometimes I don't. When the video doesn't work my monitor says it has no video signal. I'm currently using the latest bios version 049 dated 01/31/13. I've tried most of the other bios versions as well with similar results.
I'm wondering if this could be some sort of power issue for this particular motherboard. I have an external power supply (similar to laptop power brick) that I'm using. I'm wondering whats others have been using and if this could be the issue.
Computer build specs
Motherboard: DQ77KB Bios 049
CPU: Intel I3-3220T
Monitor: Hanns-G HZ281HPB
If we could, can we start getting people who are having video issues post their computer system specs. I think might turn out to be very helpful to sort this issue out.
