This is what i have so far
GA-P55A- UD3L MB
Intel i5 1156
DDR3-10600 (2X2GB sticks)
Centurion 550 mid tower case w 2 fans
400W power supply
After assembly I tried powering it on and it comes on for 1 -2 secs then powers off in a continous loop, I disassembled everything down to just the CPU and CPU fan and still problem remains. When I plug in the 4 pin 12v connector it doesn't come on at all......any suggestions?......Thanks in advance
