Red CPU LED on Asus ROG Crosshair IV Extreme - Page 2

post #11 of 17
Thread Starter 
Thank you all for the suggestions. I checked the CPU and the pins are like brand new. I'll let you all know what happens when I try the other ideas this weekend.

Hi All,

Any updates to this? I apologize for the hi-jack but my Crosshair IV Formula is having the same problem.

I was able to test my 1055t CPU in another machine and it was detected fine. Additionally I bought a PSU tester and tested the 24-pin and 8-pin connections which came up clean.

PC has been stable at 4GHz since Nov.

I'm going to attempt to take it out of the case and try each ram stick separately before I attempt to warranty it. Anyone have any luck with ASUS warranty requests?

The reason you're getting a red light is probably because your CPU fans aren't spinning. Make sure your CPU fan is plugged into the primary cpu fan (4pin) pwm fans are used to adjust speed based on temperature. If the computer cant find the fan it wont power on because it doesnt want you to fry your CPU. Thats my guess anyways. Make sure your CPU is also seated properly.

Thanks for the reply tCoLL. I have to be honest, when I first turned the PC on the CPU fan wasn't spinning. I removed the fan and heatsink and cleaned both and when I attached it to the mobo it started spinning again (4pin pwm fan) and spins each time i've turned the machine on since.

I think I need to try a clear CMOS for some reason but would have to OC all over again!

You should be fine to just write down ALL the bios settings used for your current OC, clear CMOS than reapply settings. No big deal.
