Device fails to publish initially due to low temperature.
I assembled this system around a year ago, and it has performed well. I rarely use it, mainly relying on my laptop. However, a few weeks ago it failed to start. After some experimentation—disconnecting components, pressing the power button—I discovered that holding the button while toggling the power switch would initiate booting. Once operational, it ran smoothly for hours. The next day or soon after it stopped starting again. I gave up and switched to my laptop. Later, after a short wait, it started normally when only the power button was pressed. That same day I updated the BIOS and turned off the machine for the weekend. On Monday morning, it refused to start when needed for work. After waiting 25 minutes, it finally booted, but remained unresponsive. Trying my usual method didn’t help. I cleared CMOS and tested RAM in slots A2 and B2 without success. Recently, a new problem emerged: the PC took an unusually long time to POST, and when it did, it displayed a yellow LED on the motherboard. Fixing the LED issue involved downgrading the BIOS and enabling 'Memory Context Restore'. At first, this resolved the matter, allowing a clean shutdown and restart, with normal boot the next day. (YAY PROBLEM RESOLVED) But after leaving it untouched for a couple of days, it failed again. I tried disconnecting it from the wall overnight, but that didn’t help. Now it only starts when I press the power button and wait a long time—ranging from minutes to hours. If it’s running, I can turn it off and back on with ease. But if it’s left off for several hours or a day, it won’t start unless I use my odd workaround. The peculiar part is that once it finally boots, everything works perfectly. I work remotely two days a week and use it for extended sessions without issues—no crashes, no overheating, no reboots, no unexpected shutdowns. Right now, the CPU is at 42°C, GPU at 41°C, and everything functions well. The challenge remains getting it to power on reliably.
I'm considering skipping the GPU and just rewiring everything. Running on board GPU might resolve the issue, as it worked previously. Since I haven’t touched the computer, I’m unsure if this will help. It stopped functioning properly after a year, though it held BIOS settings well. The CMOS battery was replaced today but didn’t fix it.
So the issue isn’t with the power source. I replaced my previous build with the EVGA SuperNOVA 550 GS power supply (550W). Since it’s only 550W, I removed the GPU (RX 7800 XT) and used the built-in GPU for testing. With this setup it behaves the same. However, my old system uses DDR4 memory while this one uses DDR5, so I can’t test the RAM swaps. Today I adjusted the BIOS to version 3072, which was the setting that let me boot using my method (pressing power button while switching the power supply). Now it doesn’t work, and I’m stuck with the yellow indicator light. Pressing the power button does nothing—no fans, no QLED check light on the motherboard, nothing visible. The only light I see is a blinking green one near the BIOS flash. When I try the same method, the machine boots, fans spin, and the board lights up yellow. Also, all drives are disconnected except for the DP cable (no USBs, keyboard, mouse).
I'm facing this identical issue with a Micro Center Bundle - Ryzen 7 9700x, Gigabyte B650 gamer X AX V2 (rev 1.2) [bios flashed to F33b], Corsair 32gb 6000 ddr5 (2x16) rgb. I've already returned two of these bundles for the same reason and am now on my third attempt, yet it keeps failing. My PSU is a Corsair TX650W, and the GPU is a Radeon RX 570 4gb (Nvidia 1660 Super). When the system boots, everything works perfectly, but it won't start after shutting down via Windows (64-bit Pro). I've changed the PSU and GPU before, but still can't boot unless I reset CMOS or leave the power on for at least ten minutes. I've been assembling computers since the late '90s and have never encountered such a problem with any build, no matter what components I use. This particular unit has left me puzzled, and I'm reluctant to replace the entire bundle since they don't accept individual parts returns. I'm nearing the end of my AM5 experience and even considering AM4, though it's clearly outdated. My FX8350e on Gigabyte 970 has been reliable for nearly ten years, but it's aging and I desperately need an upgrade. Today a new PSU is arriving, along with a fresh cooler to thoroughly test every possible fix, but I'm not optimistic it will solve this issue.
I changed the power supply again and it functioned perfectly. I put in a brand new 850-watt unit even though it seems excessive. The older Corsair 650W (80+ Bronze) was the issue. I replaced it with the one from my wife's machine, which is identical but still caused the same problem. These PSUs are from around 2010 or earlier, yet the FX 8320e has a 95W TDP. The new setup actually uses less power. I’m not sure if there was a change in manufacturing that forced this upgrade. I’m not very knowledgeable about PSU requirements, but it seems to work now. If anyone can explain why this matters, I’d appreciate the insight. I might test a 650W model just to confirm if it’s the wattage or something else. Whatever happens, it started and stopped smoothly. With the Corsair, my external USB drive stayed on when power was off, but it didn’t with the new Poinwer PSU. Could be the caps weren’t discharging properly? It’s odd that it worked with a second unit too. This doesn’t make sense to me, but it did. I should have begun fresh instead of just swapping for savings, especially since the time lost added up. Hope this helps others facing the same issue. PS: I only changed the PSU, not the cooler.
