I have an M5A99FX PRO R2.0 and when i turn it on, nothing happens. no boot or post. so i went in and looked at the motherboard, i saw tha the CPU LED is lit red. i looked on the manual and it means that there is a problem with the cpu or 8 pin connection. i checked the cpu and its been working great for a long time. its the fx 6100. so when i turn on my pc, the fans spin and the lights go on from the mb but nothing else happens. just fans spinning and the red led light is on. i cant figure out if my mb, cpu, or psu is dead
