Cannot enter BIOS Asus PC

Hi

I have a CM6730 Asus PC with a P8H61-M PRO/CM6630 motherboard.

I was having problems getting good Graphics performance and the topic of Integrated vs discrete GPU came up,
the options in the BIOS were set to use iGPU, since then I do not get the option on boot to
enter the BIOS.

I have tried ASUS but they want me to send the unit in for repair.

Any ideas on how to fix this?

My rig has W8.1 fully updated.

Cheers

Daniel

I don't know if this also applies to your motherboard: How to Use USB BIOS Flashback - ASUS

If it doesn't apply there may still be a way to reflash the BIOS with the right key combo on start up but it sounds like your BIOS is glitched and may even be a chip problem. Might have to go back to them.

Also assume you've seen this, F12 is supposed to work: http://www.asus.com/Motherboards/P8H61M_PRO/

Hi

thanks for the information, I believe the USB BIOS Flashback is relevant but I am not sure how it affects my warranty,
and the F12 comment on the page is very vague but I have tried using F12 in every reboot configuration I can think of
and none worked.

But I appreciate your taking the time to send me the information..
Regards

Daniel

So the PC boots up OK, but you just can't access the BIOS on boot up? One thing that can cause this is Windows 8's Fast Startup. http://www.eightforums.com/tutorials/6320-fast-startup-turn-off-windows-8-a.html If its enabled try disabling it and trying again to access your BIOS. If this PC has a UEFI BIOS try this, http://www.eightforums.com/tutorials/20256-uefi-firmware-settings-boot-inside-windows-8-a.html . Another option would be to reset the bios to failsafe defaults, although that would probably set the iGPU as default anyway. Do you have a dedicated graphics card installed? If yes what is your monitor connected too? If you don't have a dedicated card installed it should just default to the iGPU anyway no matter what you set the BIOS to. At least that's the way it works on my ASUS motherboards.

It's Delete on my two ASUS desktop PC's. I think its F2 on my AUS laptop.

That option is not coming up, pressing Del or Delete or F12 simply stops the boot process.

"DEL (delete)" button during BIOS boot sequence should let you in the BIOS.

That option is not coming up, pressing Del simply stops the boot process.

Where do you end up when it stops? What video port is your monitor connected too onboard or dedicated GPU?

Hi

here is what happens,

when I press the power button on the case or restart from Windows, when the start process begins the Monitor light is on
but a sign comes up "DVI no signal", the monitor light goes off, then after about 30 seconds the monitor light goes on and a sign
"DVI" flashes, the monitor is blank for a few seconds then the PC is on the Logon page.

Fast Startup has been disabled
There is no option to restart to UEFI settings as shown here http://www.eightforums.com/tutorials/20256-uefi-firmware-settings-boot-inside-windows-8-a.html
I guess that means the BIOS is not UEFI, I thought it was but the Manual does not say it is. I believe the Motherboard is UEFI but the BIOS is not.

I do have a dedicated Graphics Card and Monitor is connected via the Card.

I cannot set the BIOS to default as I cannot get into the BIOS.

I hope this makes more sense now.

Cheers

Daniel

Connect the monitor to the motherboards video connector and have another try at entering the BIOS. If you manage to get in, switch the BIOS back to the dedicated card. It sounds like you are actually getting in but the signal is going out of the motherboards video jack instead of the dedicated card. At least until Windows loads anyway. It's kind of weird that it would do that, usually everything would be on one port or the other not split up. The exception to that would be a multi monitor setup.

It can not be that MB is UEFI and bios not.BIOS has to support UEFI for it to work.

I believe early UEFI boards were compatible with both, or perhaps it is a OS thing, either way it is not an issue here

Some have a choice of Uefi or Legacy boot.
