The title basically says it all, it worked just fine yesterday until i moved my pc to the other side of my room because i had a room makeover or however you call it. Anyhow i noticed when plugging in the 20 + 4 pin connector halfway in ( not really plugging it in just putting it in there) my pc starts for like half a second since i can see my front panel fan lighting up and spins like 180 degrees until turning off, same with my water cooler fan. I don't know how to fix this since it worked just fine yesterday. My PSU is an AXP with 630 watt model number AXP-630P12P and sorry but i can't really tell what mobo i have since i can't turn on my pc but it is a Gigabyte mobo and it say's ht30 am3 to the right of the cpu.
