Okay so to the explaining. I basicly can't turn on my computer if I have left the - power chord in / power stripe on - when I turned off the computer. I need to turn the power stripe off or remove the power chord for 5-10 seconds and then plug it back in / turn it back on. And then it start up normally.
I bought the parts 2 months ago and built it myself. I was carefull when I built it and I've built computers before. ESD wrist strap and motherboard on a cardboard piece when I mounted the CPU and RAM.
