Yet another victim of gtx 770 not booting windows

[SolusChristus]

Got my gtx770 in the mail today from newegg, gigabyte supercooled edition. Took out my gtx680 to use in another computer and swap it with this one. However, lo and behold the computer won't boot with the gtx770. It goes to a black screen with a blinking underline curser. Once i put the gtx680 back in all was well.

Few things?..check to see if your mb bios is updated. There been a few bios bug fixes. If your mb lets you switch from pci 2x or 3x mode on the video card slot try 2x mode. On some bios and windows 8 you may have to turn on or off secure boot.

It's windows 7 and I've never had to flash my mobo. It's strange that people have to do this with the gtx 770 series.

the interesting thing here is that i can't do anything to enter the boot menu, safe mode, or bios when restarting my computer. I hit the f keys and then the mobo just makes a noise as if it won't respond. This only happens with the gtx770, The gtx680 works great. I know i didn't get a faulty card, i believe this to be a result of nvida poor driver support, making their gtx770 useless.

i updated the bios, and uninstalled, reinstalled drivers. still no work.... have to revert back to gtx 680.

Look in thE bios see if you can set the pic video slot to pci 2x mode. Some cards and mb don't work well in 3x mode. If you bought the card at a local shop bring your pc in and see if they have another brand of the same gpu.
The issue now with some gpu s how close is the gpu to nvidia refrance design or how much did they mod the card to boost the gpu speed.
With the 600 line a few vendors were caught changing there cards to where they would not pst in some mb and nvidia found out and told the vendors to stop changing the power reg to force a higher boost.

How can it be poor driver support? It's not booting into Windows therefore the drivers are not loaded and can not be the cause of the problem can they?

sorry, perhaps its not poor driver support. But its poor manufacturing support. It is very odd that after flashing my bios, uninstalling and reinstalling nvidia drivers (while my gtx 680 was in), putting the gtx 770 in another pci-e video card slot, etc, i still can't get the computer to boot up to windows with it in. I am sending it back where it came from and getting a different card. I've never had this much trouble with any radeon, or geforce card i have ever bought.

Ok i found out the answer to this problem. You have to put your old video card in the system, boot it up and go into BIOS, Set your video display adapter to 'legacy' mode. Then save the settings. Shut down your computer after it books, put your new gtx 700 series in the computer, and power it back on.

I encountered this "B2" error with my ASUS gtx 770,I dont have a Legacy Option in my BIOS and it turned out for me at least it was the Video Cards BIOS. Put it in my friends computer and it booted fine. Downloaded the Latest BIOS from ASUS and updated the card, put it in my machine and it booted on the first try xDD

Thank you so much for posting your solution, I had this exact problem with a different motherboard and it fixed it for me.
