Problem with starting in cold conditions🌡️
Hey everyone, just started a new mini ITX PC about five months ago. It’s been running perfectly with no problems. But around 1.5 months ago it began showing a cold boot issue—I’ve tried everything and still can’t figure it out. I’m looking for any suggestions or tips. For the PC to function properly, it needs to be warm. Every time I power it on and it hasn’t been running for a while, there’s no display. It seems the PC needs to stay on for at least five minutes without any video output, sometimes even USB stops working. This happens more when it’s cold in the room. If I restart it quickly without letting it heat up, it still doesn’t show anything. This started after about 100 hours of use. I’m now leaning towards the CPU or motherboard being the issue. Initially, I thought it was the GPU, but that didn’t help since it worked with integrated graphics. Then I considered the PSU, but it was the same problem again. So far, the motherboard seems likely, especially since the PC works when it’s already booted. I don’t think the CPU is the problem. If I stop using the PC and it gets cold again, the video will freeze up and go black.

It's possible the solder joint on the board isn't solid. While the CPU isn't ruled out, it's less likely. The issue might stem from something on the board, especially since a warm-up period is needed for proper connections. The board itself could be the culprit, making it hard to detect without specialized tools. If the RAM is involved, simply swapping it out should resolve the problem. For other components like the GPU, removing it might help if it's interfering. The key is to narrow down the cause by testing and observing.
I recommend trying another power supply unit. This aspect is often ignored yet it can lead to various unexpected problems. The BIOS might reset to default settings occasionally—maybe a faulty CMOS battery is the cause. Best of luck!
