Code B1 Detect HDD

Krazes · April 7, 2021

I've got a Asus ROG Crosshair VII Formula X570 motherboard, getting "Code B1, Detect HDD" on the small screen. Checked the motherboard manual and it states the code means "Runtime Set Virtual Address MAP End"

Detect HDD I believe refers to memory/storage. I have checked them both on my old PC and they work fine, lets me download Windows etc. I have done CMOS on my new PC's motherboard, reseated the ram 1 by 1 in each slot and still didn't fix the problem. My storage/memory are both being recognised in the bios. I'm using M.2 NVME's also, I've tested with SATA SSD and it's still being recognised.

When I built my PC a month back I had the same problem which was fixed by reseating the ram 1 by 1 in each slot until it let me download Windows ever since then every week I've been getting blue screens at random times then I gotta restart my PC. Yesterday I had enough then reseated the RAM then I couldn't even do anything anymore, Detect HDD errors. I got the C Drive M.2 NVME and I formatted it on my old PC and that didn't work either. I've been stuck on "Preparing Automatic Repair" or some crap and then when I boot I just get stuck on the ROG logo and nothing else happens. On my mini display it says I'm in the bios.

The blue screens I've got while using the PC normally at random times is irql_not_less_or_equal and System Thread Exception Not Handled.

I can either send it in to a repair shop.. which will probs cost me sh!t tons or I can just sell the mobo and get a cheaper one as I wasn't using open loop watercooling so there's no point with such a high end motherboard. RMA could be an option but I heard ASUS is annoying to deal with.

Edited to mark as resolved:

I've RMA'ed the Ryzen 9 5900x and it was the CPU causing the issue. They've replaced it for me.
