No screen while booting (win7)

February 2, 2011 at 18:19:57
Specs: Windows 7
As the topic says I got no boot screen while powering up my comp, everything is running fine but I don't see, but I can't for example go to the bios since I don't get any connection to the screen.

The thing is that I get connection with the screen and picture when I come to the login windows 7 window.

I've tried all my 5 dvi screen contacts without results, can't come up with why it acts like that, so please help me out if you got any idea.

System:
Os: Windows 7 64-bit home premium
Processor: AMD Phenom(tm) II X6 1055T
Processor cooler: Corsair H50
Mother board: ASUS M4A89GTD PRO
Ram: Corsair XMS3 DDR3 1600MHz 4GB
Gfx: x2 Sapphire Radeon HD 6870 1GB GDDR5
Monitor: LG Flatron w2252tq
Hdd: Corsair SSD Force Series 2,5" 60GB (boot hdd)
Psu: Chieftec Super Series 750W PSU

If you are using dual graphics cards connected together, your Windows 7/Radeon driver makes everything work fine, but your BIOS may not support it, of may need a change in BIOS settings. Try removing one graphics card to set BIOS, or remove both and use onboard graphics or basic graphics card to set BIOS. In your BIOS, you will probably need to disable onboard graphics and set the Primary Video Controller. See your manual or online manual for details.

Okey so I removed one card and I got picture while booting and got to the bios the thing is I don't really know which Primary Video Controller I should set since I don't got the manual :)

It's listed like this:

GFXO-GPP-IGFX-PCI
GPP-GFXU-IGFX-PCI
PCI-GFXO-GPP-IGFX (currently using)
IGFX-GFXO-GPP-PCI

Which should I use? Thanks!

I saw that on your downloaded manual, but no explanation and I am not familiar with the terms so I would be guessing. (for some reason I do not see the section now) Please wait for someone else who knows your board better than I do. BUT LOOK:
Manual:
http://support.asus.com/download/do...
1- Did you disable onboard graphics, section 3.5.22
2- Read Chapter 5 on Crossfire graphics, it appears to be step by step.
