CPU Speed, BCLK and Memory Speed: Boot failure.

Today I have done a complete dismantle and re-seat. I made it sure that there is no loose wires. The case speaker was already connected. But I never got any beep sound. About the standoffs .... the applied PINs are ....

One mounting hole of the motherboard does not have a supporting pin, BTW.

Now it is running. But I have to wait to decide upto tomorrow, when I will do another cold start. When the machine is already hot, boot ... reboot etc are not a problem.

Steve, I am really thinking that it is the RAM that is the issue, but I am wondering why it is failing when it is cold and why it is working perfectly when it is hot. I wish I could come to know it.
Though I will let memtest86+ run this night.

Thank you Steve and Jack, for your continuous help. :)

Arc, I really have never seen this issue. My only thoughts are, if it is the ram, There could be a hairline crack in it, that causes it to fault. When it gets hot, it expands, and basically the crack comes back together and it makes contact and does not fault. But again, I have never seen that in ram. I have seen it in capacitors on Motherboards and PSU's. That could also be on a solder point on the board too. It is usually a crack so small you can barely see it and then usually only when you know where it is. And, that is simply a guess.

If I see the issue to continue tomorrow too, I will start replacing the hardware one by one. RAM will be the first go.

Did it start today OK?

No, it did not.

Then I dismantled it. Re-seated each and everything. At power on it loaded the optimized BIOS defaults and rebooted to the desktop.

Arc did you ever build your system on the bench? (out side of the case)
Could you show us a picture of your cpu cooler and ram when installed.
My thoughts are that something might be distorting the motherboard.
My guesses are leaning towards the motherboard. It's made in layers and their are a gazillon solder joints that could be effected by distortion (flexing) or heat expansion and contraction.

Monster212, we appreciate your thoughts. I had first thought about the power supply, but all indications are about the ram or Dimm slots. At least that's the way I see it.

I know i am very late to this and didn't bother to start from the start but any chance his ram can be running at two different speeds one rated and one underrated

this does happen when ram goes bad one shows correct speed while one is not so much speecy will be what you need to use though to see individual sticks

I believe it would be helpful if Arc posted a site showing the exact ram being used.
