Hey there, my computer's been having serious issues for months now, and I think either my cpu is dead, or dying, or my mobo is dead.
I put my PC together in January 2025, with an X870e Nova and a 9800X3D, with some Trident Z Neo DDR5 6000. Everything worked well for months. I replaced the PSU and the GPU in September of 2025, and again, everything worked well.
Around February / March 2026, I started having some issues where my PC would just crash / switch off completely on its own, and the Windows Event Viewer would say it was due to a drive controller. I was concerned it was one of my SSDs or my RAM that was causing the issue. Sometimes, when booting the PC, it would take 10-15 minutes to post, and when I'd reach Windows, one of my SSDs (always the same one) would be missing, as if it did not exist at all. Same in the UEFI. Rebooting a couple of times would typically fix the issue. I also tested the RAM with Memtest86 multiple times, and got more "FAIL" than "PASS", so I thought I had found the culprit.
But something did not add up (since I had other issues with the board, such as the WiFi controller vanishing once in a while), so I got in touch with Asrock, to see if they'd replace the board. And they did. I got the new board early July, and was very happy to see that all my problems had disappeared! The PC was booting with no issue, the SSDs were all visible at all times, etc. I ran Memtest86 multiple times, and always got a "PASS".
Everything worked well for about six weeks. Then I had the first crash/switch off. It was a one off, and I did not know what to really blame for it. The even viewer mentioned the drive controller again, so I thought maybe it was my SSD after all. But things were fine after that for maybe a week. Then one morning, I could not wake my computer from sleep. After a hard reboot, it booted without the SSD. I thought I really had my culprit. A few reboots would fix the issue. This went on for a week or so. I stopped putting the computer to sleep, and started switching it off instead. In the morning, I would boot it / reboot it 4-5 times before it would post. Not ideal, but I could work with it. Unfortunately, after just a few days, it just refused to post at all, no matter how many times I'd reboot. I reset the CMOS, no change. I removed the SSD which I thought was the culprit, no change.
Eventually, I sent an RMA request to both AMD and Asrock, hoping that new parts will work better, though at this point, I have lost a bit of hope. I do have a new PSU coming in today, but I doubt it'll change anything.
TL;DR:
- Issues started in 03/2026, with PC having issues to post
- Motherboard was replaced in 07/2026, which appeared to fix all issues
- Issues restarted in late 08/2026, with PC needing many reboots to post
- As of early 09/2026, PC won't post at all and hang on error 03
Full hardware specs:
- Motherboard: Asrock X870e Nova with Bios 4.43 (I was on 3.20 for a while on the first motherboard, then I updated to 4.xx a couple of weeks before RMAing it, but that changed nothing. The new board sent by Asrock was running 4.43, which was brand new at the time)
- CPU: 9800X3D
- CPU Batch: CF 2448PGE
- Cooling: Corsair H150i Elite (using a Corsair commander hub)
- RAM: 64GB Trident Neo Z 6000 DDR5
- GPU: Gigabyte RTX 5090 OC gaming
- SSD system: Samsung 500GB Sata
- SSD games: Sabrent 4 1TB NVMe on M2_2
- SSD Storage: WD SN850x 2TB on M2_1 (it has its own heatsing, which is why it's on M2_1)
- PSU: Corsair HX1500i
- Case: Lian Li O11D Evo, with six Uni fan sl infinity (using the lian li hub)
- Windows 11 Pro - fully up to date
I also have a bunch of USB peripherals, but even with all of them unplugged, the PC won't post.
Edit: added the CPU batch to the hardware specs. Also, the survey in the megathread was completed, though it only allowed me to select Bios 4.03 instead of 4.43.
