Crosshair-V Formula-Z not POSTing anymore

Over the last couple months, my computer was starting to have issues getting past the POST. Sometimes it would, sometimes not and it would always hang at the ASUS ROG screen telling you how to get into the BIOS, but never budge from there. Sometimes it would even say "Updating bios, don't restart or power off your machine" and I have no clue how it got to that stage. My short term solution was to just stop turning off or putting my computer to sleep, and I'd have absolutely no problems as long as it was on.

Today I decided to try and figure out what was going on and fix it. First I tried clearing the CMOS. It booted up, went into the BIOS, I told it to exit without saving (since I didn't change anything) and it booted windows no problem. So I restarted it to see if it would happen again or boot properly. It froze at the splash screen again.

I tried clearing the CMOS, and even removed the CMOS battery and switched off my PSU for about 10 minutes while I looked up some other possible solutions on my phone. Popped the CMOS battery in, turned on the machine, went into the BIOS settings, changed the chassis fan settings (default made them loud) and hit save and exit. It reset, and froze at the BIOS screen again, but my changes to the fan profile had taken effect.

Tried restarting several times from there and could not get past the BIOS splash or into the BIOS. I finally managed to get in to windows again, downloaded an updated file (Was on v2002, updated to v2201) and flashed to the BIOS using AI Suite. Disaster.

I now get error codes on the board that are never consistent and will be any of the following: 00, 05, 10, or 5d, most of which aren't defined in the manual or are defined as "reserved for future codes". I can not get into the BIOS at all, never see the ASUS ROG splash screen, and I'm thoroughly at a loss on what to do now.

I've unplugged everything USB except a cheap 8 dollar keyboard that I keep around as a spare, removed both GPUs, all RAM, all SATA cables (HDDs, SSDs, DVDs) reseated every cable between my PSU and MOBO, none of it made a difference (though RAM being out did result in error 50 which means no RAM, per the manual).

Is my board bricked? Is there a way to re-flash via USB thumbstick when you can't get into the BIOS?

Sorry for the very long post. If there is any other info needed, let me know and I'll provide it.

For one I would never flash the BIOS in anything but the BIOS. Software based BIOS flashing is.... well it sucks. I would download the file and reflash using the BIOS EZFlash and a USB stick.

Second, have you tried each stick of memory one at a time?

I have rarely seen a board die like this, although it is possible, but we want to eliminate all other possible components first.

Oh and there is a way to reflash with a USB thumb drive when you can't get into the BIOS. Check the manual but there should be a specific USB port on your board listed as the USB BIOS Flashback port. You need to put the latest BIOS on a FAT32 formatted thumb drive then plug it in and hit the USB BIOS Flashback button. It should take the BIOS and reflash.

Also have you got a pc speaker plugged into the system header? If so, any beep codes at all with just cpu + mb + power?

EDIT: Ah just noticed you got a no ram error code. In that case pop in one stick of ram, plug in a speaker to the sys header and listen for beep codes.

I don't have a internal speaker, and I'm not sure if any of the other computers in the house have one either...


I'm never going to use software to do so again. This is only the second time I've ever had to flash a BIOS in my life.

I did try each RAM stick in each slot and got no different results.

However, my manual didn't entail how to use a BIOS flashback, and the only directions to create one were using the AI Suite, I did find directions to manually create and use one online. I used my ancient laptop (Running Ubuntu and used for my 3D Printer) to create the file on a flash drive. This did work. I'm back in action. Thank you so very much JImmysmitty. This was the worst things that's ever happened to any of my computers.
 


It is pretty simple. If I remember correctly you need to download the BIOS file to a FAT32 formatted USB stick then do as I said. I just wasn't sure which port was the Flashback port on your board as I have a Asus but not that board.

As for flashing the BIOS, it is easy from the BIOS. Similar. Make sure you have the BIOS on a thumb drive and plug it in. Go to the BIOS and go to the EZFlash tab. Then click flash and select the file. This way makes sure nothing can go wrong.

Glad it is up and running again though.
