bmrowe Posted October 24, 2023 Share Posted October 24, 2023 (edited) I updated a working system to an ASUS TUF b760M D4 and an intel 13500 (from an 11500 and b560m motherboard). Things look fine in bios, and I can leave the machine in bios forever. However once I boot to unraid, the system will restart after exactly 15 seconds and do this over and over. I think I've eliminated most potential hardware issues - I've simplified the system down to just the motherboard and CPU. I've tried GUI mode and safe mode, and all restart in 15s. The memtest sends it back to the bios splash screen. I tried a random distro of linux on a different USB. Same issue occurred once I booted into it. I also tried a fresh download of unraid, same problem. Any ideas on things to try or what might be happening? Edited October 24, 2023 by bmrowe Quote Link to comment
JorgeB Posted October 24, 2023 Share Posted October 24, 2023 That suggests a serious hardware problem. Quote Link to comment

Although not a 'fix' it is worth pointing out that if you boot in UEFI mode you need the latest version of memtest from memtest86.com which supports booting in UEFI mode as the version provided with Unraid will only work if booting in legacy mode. 1 Quote Link to comment
bmrowe Posted October 24, 2023 Author Share Posted October 24, 2023 I've got a replacement motherboard coming tomorrow and I ordered an extra power supply to test. I can't imagine its the CPU, but that would be the last possible thing. I don't have a way to boot in legacy since this motherboard needs a graphics card to enable legacy boot and I just use the igpu. Quote Link to comment
bmrowe Posted October 25, 2023 Author Share Posted October 25, 2023 Following up on this. Replaced motherboard - same issue. However, I tried the new power supply and it worked! I'm super confused how a power supply could fail at the exact time I was replacing other parts. Has to somehow be connected, right? I thought maybe cable related and a cable got pinched while doing the install, but I used the old cables with the new power supply. Quote Link to comment
maxistviews Posted October 26, 2023 Share Posted October 26, 2023 Perhaps it was as simple as re-seating the cables. When you installed the new parts the cables were improperly seated? Quote Link to comment
