Hi,
The PC will start when I connect the power outlet, but not immediately after pressing the power button. It doesn't always work. Sometimes it happens after the PC has been running for a while and then turned off, but later the plug is reinserted. If I leave the PC unplugged for about 10 minutes, the start-up when the plug is connected doesn't occur. No other PCs have experienced this issue, so it might be a power supply problem, though I'm not sure. Any suggestions would be helpful.
Regards Steve

Make sure automatic restart following power loss is not set as the default.

Hi
Thanks for the suggestion. However, while reviewing the BIOS and the manual for this old motherboard, I couldn’t find any specific mention of a restart power failure. It’s a GeForce6100PM-M2 board paired with a Sempron CPU, running Windows XP. It’s quite outdated.

I’ve been removing one by one the various front panel connectors, but it doesn’t seem to help. Maybe there’s a short circuit or something similar. I’m sure the power supply is fine since I swapped in a relatively new unit that works perfectly.

Aside from issues with the motherboard itself, I don’t see any other clear causes for this problem. If there are other potential reasons, I’d like to investigate further.

I might be the source of your power issues. I have computers connected through a KVM switch, and if we power down three of them at once, only one tends to restart while the others stay off. These devices aren't configured to reboot automatically after a power failure.

Try disconnecting the computer from the wall immediately after use. While unplugged, press the power switch for 20-25 seconds, then plug it back in. Does it power up instantly or require you to activate the front panel switch?

I suspect the issue might be related to the capacitors in the computer holding a small charge longer than the others.
