I removed everything from the motherboard and even tried another CPU |
| 27 |
that used to run on that same motherboard. No luck. I can't test the |
| 28 |
power supply in my P3 router because the CPU power plug is different. |

I should have said before that every couple times I try to turn it on, |
| 31 |
the CPU fan spins about 2% of a full rotation and some of the LEDs |
| 32 |
along the back light up for a second. |

Would you guys say it is most likely the motherboard at this point? |
