DZ68DB - Continous reboot, no Welcome screen, no BIOS setup

if i have a second monitor attached (via hdmi) i'm no longer see any welcome screen and messages (have 2 displays (Apple dvi-d single link & LG hdmi)), also cant use a post keys (f2/f10) to enter bios setup, boot menu etc., even to enter raid utility of softraid ad-in card (f4/ctrl+s), keys just dont work


this mean i cant use a post keys, cant enter a setup, cant enter a boot menu, just cant see what happening with my system. only see as mobo goes cold reset continiously, because of your undone product even cant find any other hdds on system with empty softraid installed, in spite of correct settings in the BIOS (hdd first), and that mean my hdds goes to trash soon (too many shutdowns), and to boot i must disconnect second display to just see what happening. i cant understand that. it's about a year pass as product came to the market, and still no working solution released. what's wrong? in complex with other minor bugs and flaws, I find this product incomplete and not subject to release for sale. shame on you.

my system:

DZ68DB (BIOS 0032)




16GB DDR3 Sammy


IGD HD 3000


Sil3132 SR card


Apple Cinema HD display (1920x1200)

LG TV (1920x1080)

ps. i never seen such piece of crap like this mobo, it's about a year! omg... i think i never buy from intel anymore.

You may want to first check whether both monitors work or not under Safe Mode.

Make sure the memory is fully compliant with the memory controller which is located on the processor, compatibility information can be found here:

Furthermore, you can clear CMOS and proceed with a BIOS Recovery update. Instructions on clearing CMOS:

BIOR Recovery:

Test using different driver versions in case it does work under Safe Mode.

Feel free to contact the technical support department for technical assistance along with these testing results; since this is not a known issue but an isolated problem with your board, technical assistance will help you address the problem and get the proper solution for your specific situation.

Thank You Karla for your prompt response.

first, I admit that is a specific problem with the Apple HD Cinema M9178LL/A, but it's fully DVI-D Single Link compliant (not for sure about HD 3000)


second, both monitors work flawlessly with discrete add-in card, even on this mobo


then, bios is ok, mobo boots and works fine after reintegration, memory is ok too, it's Sammy M378B5273DH0-CH9, it can't be incompatible (sure, i also chek it with memtest with no errors), in fact, the trouble is to see any bios message when i have second monitor attached and sometimes has issue with entering setup during post, and i cant understand this shutdowns on any fail, this behavior can ruin my hard drive, and i'm worry.looks like we have weak/undone bios features or HD 3000 vesa modes compliance issue. that's hard.
