i just switched my case so when i get everything into the new case i go to power up and it powers up but one of the wires was rubbing on a fan so i pulled the cable out of the power supply, i open the case and fix the wire wich has no damage, i reconnect the PSU and hit the power button but now the cpu fan on top of the heatsink spins for like 1 second and thats it, any ideas?
