Question Can not enter Bios

[Flow483]

Hi there and thanks for any help in advance
I have built many computers and never have had issues until now. I just built a new computer and I can't get into my bios. .its almost like my computer is booting too fast before it recognizes my keyboard, then it goes to a backscreen showing my Mobo manufacture. At this point no keys are registering and I have to restart or turn off my computer to get off that screen. From my personal research the only thing I was able to come up with was that sometimes with using Riser Cable it can cause some sort of issue or similiar? Wanted to post here before making any more changes or adjustments.

Computer parts
Mobo: Gigabyte B550I AORUS PRO AX Mini ITX AM4 Motherboard
CPU: AMD Ryzen 9 5900X 3.7 GHz 12-Core Processor
Memory: Corsair Vengeance LPX 32GB (2x16) DDR4-3600 cl18
Gcard: 3070 Ti EVGA ULTRA
Storage: Crucial p5 2TB M.2-2280 PCIe 4.0 x4 NVME SSD
Case: Cooler Master Masterbox Nr200 (pre installed cooler and power supply) Mini ITX

Thanks again

Try a different keyboard, preferably a wired model. I've seen MANY builds that won't recognize certain models of keyboard initially.

In lieu of that, as a first effort, you can try removing the CMOS battery just in case for some reason it was set to fast boot or ultra fast boot by default or if it was a returned part. Just pull the CMOS battery for about three minutes. Then put it back and try again. If that doesn't help, then try a different keyboard. Especially for wireless models, some systems simply refuse to recognize them until after the BIOS has been entered and configured. I really doubt your riser cable is related but if neither of these other solutions help you can always try pulling the board and building it on the bench on the motherboard box or a piece of cardboard, with minimal hardware AND with the graphics card installed directly in the PCIe slot so that you can get it configured, and then after you are able to access normally you can rebuilt it in the case.

That would eliminate the riser cable as being the problem.

I can confirm it is not the keyboard. Tried two different high end wired keyboards before initial post, should have mentioned it. I will Try the CMOS battery and get back to you.

Thanks

Try a cheap wired keyboard or even a cheap wireless one. Most of the problems I've seen in this stripe HAVE been rather higher end models including my own which I've run into this problem with previously when trying to use it initially on a couple of new builds. But, ok.

I am about to remove the CMOS battery here in about 15mins. I will let you know how it goes. Hopefully it works, if not I hope your around for other soltuions

Is Clearing the CMOS accomplishing the same thing as taking the battery out and putting it back in?

Windows 11 lets you boot to BIOS.

No. And this is the procedure you want to use. EXACTLY as outlined.

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 about three to five minutes. In some cases it may be necessary to remove the graphics card to access the CMOS battery.

During that five minutes while the CMOS battery is out of the motherboard, press the power button on the case, continuously, for 15-30 seconds, in order to deplete any residual charge that might be present in the CMOS circuit. 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, A-XMP or D.O.C.P 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 BIOS to fully reset and force recreation of the hardware tables.

Computer fixed and running beautifully, it was jus booting to fast and BIOS reset worked. Thank you

Glad it worked out for you Flow.
