I have the mainboard Intel DQ45CB, with Intel express chipset Q45/Q43.
The mainboard has two digital connectors (one DVI-D and other DVI-I)
If I use only one monitor all run ok.
If I connect both monitors following things happen:
The initial Intel screen (where you can press f2 etc... does no appear, both monitors stay black until de OS windows 7 start.
After that all runs OK but if I dont use the PC from some time (10-15 minutes) both monitors go black and I can not restart. I need to push the reset button.
Some intel technical or someone can give me any solution?
Sorry for mi bad english.
