Asus P7P55D-E Pro post fail, most of the time.

Nope, just want my system to run.

I have the same problem, maybe not as severely as yours, as I understand.

I have Asus P7P55D.

Out of 10-15 cold bootups, I have one POST failure and the VGA LED remains lit red. I shut my computer down with the power button on the case and power it on again. Then I have a successful POST and Windows loads normally. Once loaded, Windows runs indefinitely without any problem.

I have no problem with warm reboots, such as the restarts after program updates.

Nothing is overclocked. Everything is at default value of AUTO, plus many settings in BIOS, which I have no use for, are DISABLED, such as Serial port, 1394, Express Gate, Virtualization Tech, C-State Tech, e-SATA/PATA controller, etc.

But for the last three months, I am not having the issue. 1) This could be due to the BIOS version 1702, which I had installed in mid-June. 2) This could be due to summer season. All cold boot-ups are actually warm boot-ups because of high ambient temperatures. 3) This could be due to the fact that my motherboard learned how to boot properly after many failures.

If ambient temperature is a factor, I will learn soon as the cold weather is closing in on my computer.

My VGA card is, Sapphire Radeon HD5770. It is also at stock speeds. Not overclocked at all. I am no gamer. This VGA card is marketed several months after P7P55D.

It also takes 15-16 seconds before I hear a beep sound and then POST screen appears.
