Hello,
Yesterday, I came back home after 2 days of absence. I tried to start my pc. As soon as I plugged the pc in, I have noticed that it has automatically started to run. Unfortunatelly, it has only started. It stucked just after that. I couldn't turn it off anyhow, I have tried pushing reset, power, or holding power for 3 seconds, but the pc seemed not to respond. The only solution to turn it off, was to unplug it. Since then, every time I plug it on, it happens again. Fans are working correctly, as well as the power LED. The HDD LED, lits for a split of a second at the very beginning, but then it does not. Although I can hear at the beginning the sound of my DVD-ROM, the open button does not work as well. I have tried plugging off my HDD and DVD-ROM, as well as network card, USB ports and the front panel. The result was still the same, what means that the buttons are fine, and the problem is either in my motherboard or power supply. But then I checked the power supply to other pc, and it worked properly. I have also tried resetting CMOS and swaping RAMs. Still no result. I have Gigabyte GA-K8NF-9, and my CPU is Athlon 3000+, and my power supply is 400W.
In the last few weeks, after coming home from a weekend(and my pc was unplugged for about 2 days), I had difficulties in starting my PC. After plugging it in and pushing the power button, it seemed to start for a split of a second, but then it turned off. Just the power LED has lit for a moment. Solutions for this was a quickly pushing of the power button. It has been happening ONLY if the PC was unplugged for a longer.
