Z77a-gd65 hangs on bios screen and also doesn't boot

Question

i7 3770k
MSI GTX 670
2x8GB 1300 memory.
I cannot get into the bios.  If I hook the monitor to the gtx 670, I can get it to display the msi bios screen "temperature, boot device priority" but that's it.  There's no data, no temperature, just like it put the bios image up and then hung.
Right after hitting the cmos button, I get the following:
E7751 IMS  v10.5 4/27/2012
i7 3770k 3.5ghz
16gb ddr 1333 dual channel
It doesn't seem to let me hit "f1 to setup" or "f2 to continue" with a ps2 keyboard.
If I boot from the cd to try and install winki, there's some info that flashes too fast to see but its to the choice of install, and then whatever option I choose, it will display a clear screen with the logo and eventually the screen goes black with a blinking cursor.
If I boot from a usb linux drive I have, it again goes through the boot choices, and then the screen goes black a few seconds in.  Doing this I think I got the mainboard leds to display "ff"  otherwise they display either "00" or "ad" or "ae".
The monitor is apple monitor through an adc to dvi adapter.  I've used this for years on an ati radeon on a p4 windows setup so it shouldn't be a problem but...  if I hook the monitor directly to the mainboard onboard video, the bios screen graphics stop hanging open, the screen just immediately goes black.
I've tried clearing the bios with the button, switching the multibios, and jumpering the cmos with the power off.
I have not tried flashing the bios, I was thinking about doing that through winki but it won't load.
Thanks.

Answer 1

I tried just one stick of ram in a different slot but no difference.
And as in my first post I tried the onboard a bit but it was about the same.  Actually I forgot what I tried, I just now tried the apple cinema display to the onboard video card and unpowered the gtx 670 without taking it off the board and the display doesn't come on at all.
I think that was what it was last time I tried the onboard, that I thought it might be something about the adc-dvi converter.  But it works besides.
Why would it be able to get to the boot choice screen but not the bios though?  The PSU has a 7 year warranty, its probably decent, manual says 62.4a +12v .8a -12v
One other thing, if this matters.  The first two blue lights are always on on the motherboard, the voltage indicators or whatever, but when it tries to load winki, the other blue lights blink.  And right now, with the monitor on the onboard, all the lights are on.  But the monitor isn't.
Also, do you need a mouse plugged in, that probably wouldn't make a difference, I think I've tried that as well.
