I have just gone through a back-to-back RMA with ASUS regarding my motherboard (they sent my original motherboard back to me without fixing anything that was wrong with it, and then advance shipped me a new one). I received the new board yesterday and reassembled my computer. Everything seemed to work great again, with one exception of a few occasional boots where the computer would temporarily not post from being powered off. I turned it on this morning and it booted up great, I surfed the net, played a short game of plants vs. zombies, and then turned it back off and went to the gym.
Since I've returned from the gym, it won't start up. It'll power up but will not post at all. On initial power up when everything worked fine, my GPU fan will blast at 100%, but as the computer posts it backs down to an inaudible level and now it is not doing that. I have done the following: popped the motherboard's cmos battery out, tried booting with just 1 memory stick, tried using the onboard video instead of my GPU...but nothing works. Same result.
I've recently got a noctua NH-U12P heatsink/fan and that sucker cools the heck of my e6750 CPU (idles 20 degrees celsius at a comfortable room temperature according to the program coretemp). I've owned that processor for close to two years now, and it has been overclocked from day 1 without any noticeable problems. In fact, last night I ran super pi and prime95 simultaneously for 15 minutes problem free with neither cpu core ever exceeding 43 degrees celsius. During the run, cpu-z showed my vcore to be slightly above 1.40 volts.
I don't have a second computer in which to test my cpu, and since this is the third time in the past three weeks where I've had to uninstall the cpu heatsink/fan (which is a pain the ass) I'm pretty frustrated. I just want my desktop to work!
Given the information, is it more likely to be the older cpu or new motherboard that is bad? And what would be the best way to find out for sure which one it is?
