Replacing Heatsink results in failure to POST

post #1 of 3
Thread Starter 
So I've tried to replace the standard heat sink for my processor with an aftermarket. I followed the simple steps of, removing the old heatsink, removing the processor, cleaning off the old thermal paste with cu-tips and rubbing alcohol, drying the processor with cu-tips, applied the thermal paste in a nice even surface, put the processor back in, attached the new heat sink, reconnected all power cords inside the case, plugged everything back into the case.

Everything in the computer powers up except that on the motherboard, to the bottom left of the processor right above my first pci-e slot, there is a blinking blue LED light. In addition, the computer doesn't move on to POST. From here I've gone through and removed all unnecessary components so it would be down to the bare minimum to start. I've removed all the ram except 1 stick that is in the slot furthest from my cpu (as indicated by the motherboard manual). I've also removed 1 of my gpus as well as my sound card. Still I am running into the same issue of the computer not posting and the blinking blue light in the same location. At this point, to test to see whether or not the heat sink was just not attached properly, I removed the new one, cleaned the old one the same way I did the processor, and then reinstalled the old heat sink. Still I am running into the same issue which has me extremely worried that something has gone wrong with my processor.

Here are my computer specs that may be related to the issue:
i7 990x Gulftown
Asus P6T7 WS Supercomputer
Corsair Dominator 20 GB DDR3
2 Crossfired Radeon HD 6990

Here is the location of the blinking blue light on the motherbaord


Any help and advice at all to resolve the issue would be greatly appreciated. As of now I'm currently contacting ASUS technical support to try to figure out what the blinking blue light means (its not specified in the manual) however not much progress is being made.

Thank you for any and all help in this matter

You sure that the backplate (if any) isn't touching the motherboard or the case?

No it isn't touching neither the motherboard or the case. As an update I got through to Asus tech support and they said it may be an unstable board bcecause its not giving me any sort of diagnostic beeps and they can't identify why there would be that blinking blue LED light. This also sorta makes sense because when I first go the board I tried to do some slight overclocking which resulted in unable to post or causing the BSOD 5 minutes into windows starting...and I was even using some of the OC profiles that were already in the BIOS. However, because everything was working at the complete default settings and I was in desperate need for a computer that could handle 3d work I decided to just keep the board. Thankfully Asus is still RMA-ing the board in case it is a instability issue.

However, I'm still somewhat worried that something else might be causing this issue other than the mobo that may be processor related so any other advice or help would still be appreciated
