I was in the bios when my power supply died (thermaltake thoughpower RGB 650W gold), so I bought a new one (seasonic focus 850W gold) and booted my pc, everything worked until I tried to enter the bios again, and everytime I try to get into the bios, the screen just get black and I get the A9 error.

I already tried clear cmos, flashing bios with the last update with an usb stick and also an older update and it doesn't get into the bios, what should I do? (I can use it without any problem but can't get into the bios)

Pc specs
Asus Crosshair VII Hero (wifi) X470
Ryzen 7 2700X
16GB (2×8) Corsair vengeance 3200Mhz
2TB barracuda 7200RPM
MSI 2080ti gaming X trio
Samsung evo 970 plus 250GB

If you find some akward grammar is because I used google translate to write most of this post 😅

BIOS Hard Reset procedure

Power off the unit, switch the PSU off and unplug the PSU cord from either the wall or the power supply.

Remove the motherboard CMOS battery for five minutes. In some cases it may be necessary to remove the graphics card to access the CMOS battery.

During that five minutes, press the power button on the case for 30 seconds. After the five minutes is up, reinstall the CMOS battery making sure to insert it with the correct side up just as it came out.

If you had to remove the graphics card you can now reinstall it, but remember to reconnect your power cables if there were any attached to it as well as your display cable.

Now, plug the power supply cable back in, switch the PSU back on and power up the system. It should display the POST screen and the options to enter CMOS/BIOS setup. Enter the bios setup program and reconfigure the boot settings for either the Windows boot manager or for legacy systems, the drive your OS is installed on if necessary.

Save settings and exit. If the system will POST and boot then you can move forward from there including going back into the bios and configuring any other custom settings you may need to configure such as Memory XMP profile settings, custom fan profile settings or other specific settings you may have previously had configured that were wiped out by resetting the CMOS.

In some cases it may be necessary when you go into the BIOS after a reset, to load the Optimal default or Default values and then save settings, to actually get the hardware tables to reset in the boot manager.



If THAT fails to give you BIOS access, then I'd contact ASUS about an RMA as not being able to go into the BIOS is a sign of a faulty BIOS ROM or some other issue not allowing the backup BIOS to kick in, for boards that have one.

Flashed the bios once again to 2801 and back and now it boots but I can't enter to the bios without getting the code A9 again, should I try an older bios?

So I tried hard resetting it again after flashing the bios and it didn't work then I used an HDMI instead of a Displayport (connected to the GPU) and it booted into the bios, thanks @Darkbreeze
