No image until Windows loads! Need to access BIOS!

[DarthRevan]

Hey guys, well, since I bought my 3D Asus VG278H, I haven't been able to access the BIOS. After turning the computer on, all I get is a black screen, until I can see my Windows loading and my desktop. I didn't worry about it by that time, but now I need to access my BIOS to format my computer and I can't!! What do you guys think is causing this?

Try another I/O. What MB and GPU?

 

[DarthRevan]

I have a GTX 460 + a GTX 280 (for PhysX), they are on a Gigabyte X58A-UD3R

press F2 or whatever enters the BIOS anyway. some LCDs take few seconds to show non-native resolutions. it might show up. also analog cable (VGA) is more likely to work.

Though the monitor may not support the 640x480 resolution while BIOS and OS are loading, Init Display First may be set to the other graphics card that's not driving the monitor:

This.

Start pressing the Delete key repeatedly right after you turn on the power. Also, if your Gigabyte board is like my ASUS Sabertooth board, if you have a USB keyboard make sure it is plugged in to a USB 2.0 port to increase the likelihood the machine will detect the keyboard early enough in the boot process to allow you to get in the BIOS.

Once you get into the BIOS, there will probably be a boot delay option you can set to determine how long the system waits to allow you to enter the BIOS before booting the OS. You may want to reset this option to a longer wait time, at least until you are reformatted and back up and running again.

I thought about pluging the monitor on the another card, but I remembered my old 21.5" was working OK on the same config, so it must be this delay you guys are talking about.
I'll try to do it! Thanks!

Well, it didn't work in the end. It seems I was able to ender the BIOS, because I got permanently stuck with a black screen, and windows wouldn't load, but I still got no image after waiting a good ammount of time!

That's a pretty good sign that your computer is using one of the other video card outputs as the primary display during boot. Move the current monitor (or use your spare) and connect it to the other available video outputs until you get a picture during the boot process. Then you can get into the BIOS to make the changes you need including changing the primary display during boot so you don't have to do this again.

Agree.

This is an older X58-based board which doesn't have any type of onboard video. You indicate you have both a GTX460 and GTX280 installed (w/GTX280 being used for PhysX once you get into Windows). Have you tried hooking up the monitor to the GTX280 (or a separate monitor to each card) at boot to see if the system is trying to initialize the GTX280 at boot instead of the GTX460? At boot time, the system doesn't care what you intend to use the GTX280 for - it only sees it as a normal graphics card. And, if it happens to be in the first slot to be initialized, the BIOS will try to use it as the output device.

If you can get into the BIOS, you'll need to know specifically which slot you have the GTX460 installed into so you can change the BIOS to initialize that slot as the initial display. In the end, you also have the option of trying to pull the GTX280 temporarily from the system so you are only booting with one card to see if this makes a difference.

Oh yeah, that did the trick, thanks guys!
I just had to plug the monitor to the GTX 280, and Windows 8 is running smoothly now!

What bothers me is the fact that on my old 21.5" Screen, I was getting the image on the monitor of the boot screen, and it was plugged to the GTX 460, just like the new screen is, and I hadn't done anything on the BIOS to change the primary PCI-E slot. Only on the new screem that I had to change this!

I had touble with GT520, it was selecting DVI for some reason as default output
VGA only began to work after windows finished booting up.
I've stumbled upon article stated that VESA had some Plug & Display (P&D) standart, according to which pin8 supposed to have Charge Power + signal similar to pin16, but up to 20 volts
So i measured it, and it was 5 volts
I tried to shortcircuit it with tweezers to ground, started pc, and somehow it seems that it done the trick, VGA became default.
It thought i would have to solder some kind of jumper from pin8 to ground, or try to debug the scematic, to find what causes that beavior, but then i've tried to start pc multiple times without shortcurcuiting pin8, and it seems to be working through vga just fine for now, but still has 5 volts on pin 16
UPD: While attaching picture i actually saw that i'm kinda retard, and misunderstood picture looks almost like DVI, but it's different port that DVI, it has 10 pins in row vs 8 in DVI, and i shortcircuited 3 pin from right in 1 row so i actually shortcircuited pin6 which is DDC CLOCK
Will try not forget to update if anything changes
