PC acting oddly, repeatedly restarts boots. Requires immediate help.
This PC has been running smoothly until I replaced my GPU and switched to an integrated graphics card. The process is typical: power on, keyboard and mouse light up, but the motherboard LED stays stuck on VGA. Once I shut it down and restart, everything works fine without errors. To troubleshoot, I tried disabling all USB devices, setting memory speed to auto (2667MHz), and even testing different BIOS versions. Nothing changed. I’ve also swapped out USB peripherals without fixing the problem. It’s frustrating—especially since I don’t have spare parts and this machine cost a lot. I’m worried the CPU might be the issue, but I need advice on what could be wrong.
Based on what I've seen, a PC can adapt its behavior over time, though it's unclear exactly what this adaptation relates to here. The VGA LED problem seems to resolve itself after a reboot, suggesting the system expects the PCIe slot to be ready. I had a comparable issue with my RAM after installation—initially it triggered error beeps, but once fixed, it stabilized. My motherboard would display RAM error sounds for some time post-installation before recognizing everything was fine.
You're concerned about an unusual issue that seems to affect your PC only under certain conditions. After researching, some users suggest the problem might be related to the CPU, motherboard, or power supply unit. It's puzzling, especially when it happens with memory set to auto or no USB devices connected. You're wondering if a component is faulty or if it's just a bug. It's natural to worry about whether this could mean your system is failing and might stop working completely in the future.
I couldn't locate any information about PCIe modes beyond auto, gen1, gen2 or gen3. My motherboard is an MSI Z490 Gaming Plus. Did I overlook something? There’s one notable observation though. I turned on "Ignore detecting VGA," which now bypasses the VGA LED and turns off, but my PC still fails to boot unless I power it off and restart it twice, as usual. Perhaps this isn’t related to VGA at all? This is perplexing.
This would align with what you envisioned. Switching to PCIe 1.0 could make a difference.
You're considering stress/stability tests for your PC. That could provide useful insights. The Anta Extreme test on memory already confirmed stability, so it seems your RAM is performing well. You mentioned checking for errors on RAM—likely using tools like MemTest86 or similar diagnostics. The fact that PCIe Gen1 didn't resolve the issue suggests the problem might lie elsewhere, such as in power delivery or cooling. Keep monitoring performance under load.
It was the motherboard that caused the problem. I attempted another type of RAM, but it didn’t help. After that, I replaced the motherboard and the issue was resolved. Thanks.
