Ga-Z68x-Ud5-b3 after bios update there is no display

[bloodysco]

today i updated my bios via @bios from f7 to f10. Everything was fine until restart. It doesnt boot. so i reseted bios from on board cmos sw and it booted.
But main problem is whenever i change anything or not just save bios screen goes black and nothing else. If i reset bios via sw or taking battery it boots and works normally or works normal but there is no display.it boots win7 i can hear opening sound of windows but somehow there is no display.
i also tried backup bios to kick in (pressing power button till close) somehow it also doesnt kick in or work.
i can use my pc if i reset if i do anychange to bios it just goes blank.i can play for 2 hours without any problem with reseted bios.
Also if i shut down my pc again it doesnt boot.i have to reset bios to get it work.

Go into Bios and load optimized default, restart and see how that works out. If you get a successful boot then you can make changes in your bios.

Somehow if i change anything or save bios it doesnt start. Blue led over graphic card is working i can hear its booting and working but it behaves like there is no graphic card. İm sure my graphic card is working couse if i reset bios via cmos sw or battery it boots i get checksum error and f1 and works.i play starcraft2 - wow anything without problem.

I'm not sure on this and you may need to wait until Dark Mantis or someone with a bit better Knowledge than me on this,but, what could be happening here is that you now have 2 different bios versions (one on primary ie: newer bios version, and an older version on the backup bios chip) and there could be a bit of a conflict at bootup if there is a problem with the flash...Maybe, I am just speculating here and don't want you to flash over your backup bios to match the new one if the new one is buggy.

As for future flashes it is recommended to use Qflash and not @ Bios because @ Bios is windows based and can be very flakey and brick your board!!!

You could try reflashing using the Qflash and make sure you Disable the 'Keep DMI Data' before you do it. See if that helps you.
