So basically, I had this thing up and running last Thursday. The installation was simple enough and I took every precaution there was to building my computer. The ONLY problem I ran into was that at first, the computer would not boot up, more specifically, the computer would startup for 2 seconds, then shut down, and etc. looping on and on. After reseating my CPU, the computer managed to boot and post. I installed W7 and other various drivers. Come this Saturday, I woke up only to find that my computer had begun the previous looping action as stated before. It would turn on for 2 seconds then turn off. After going through every item on the checklist carefully, I decided to breadboard my computer. I am at least 90% sure it is not my GPU, RAM, SSD, HDD, or Case but convince me otherwise. The more suspicious parts are my Motherboard, CPU, PSU, and 212 cooler. After testing my PSU on two other computers AS WELL AS using an old PSU on my new build, I came to the conclusion that it was not my PSU. So the problem lies either with the Motherboard or CPU. Do you guys at TH think i've done all I can? I already sent in a RMA request from and will ship out my MOBO and CPU soon. PLEASE give me any insight into what might be wrong, and if this is just a case of a faulty MOBO/CPU.


Edit: ALSO, one thing that really puzzled me was that the internal case speaker MADE NO SOUND AT ALL. No beeps to tell me what was wrong. No beep to tell me that I had no memory installed. Just pure silence. Hope this helps.

  1. Try reseating the CPU again, the HSF is spinning?
  2. I've tried reseating it. The fan spins for 2 seconds then shuts off. I still have no way to tell if it's the CPU or Mobo. I'm also scared that another part might have shorted these components.
  3. You have the same symptoms you had before, breadboard it again and try first with the CPU only, next add a stick of RAM. It might be a short in your case, did you use the standoffs for the mobo? Make sure the HS backplate doesn't touch the case, it's pretty common.
  4. I did use the standoffs. Installing one stick of ram didn't help. In fact the mobo doesn't even make a sound that tells me No ram is there. The HS was not touching the case but I noticed a small screw that wa touching the HS on the mobo.
