I ended up just going into power settings and turn it off. Last night I shut down my computer twice to unplug and plug my second monitor. Was looking in Reliability history and event viewer. With the Kernel Boot 29 error it showed an error message of: Windows failed fast startup with error status 0xCD4. I also noticed that on the 29th which was the day I enabled Asus P8Z77 WS PC Diagnostics there was the same error messages logged.

In Need Of Diagnostic Help Please

I likely would not have noticed unless I looked in reliability history or event viewer. Even went and left Asus P8Z77 WS PC Diagnostics on overnight and turned it off and on, no issue. I went to class but in the morning I went ahead and shut it off, I want to see if the same issue happens after being off for a few hours.

Asus P8Z77 WS PC Diagnostics Do you have any idea what may have happened? Even if it did, turning it off should revert any issues. I understand that Fast startup is more like a hybrid shutdown state where a system image is stored in the ram? And the various components are turned off. Any help is appreciated!

Thank you! Usually, updating the BIOS wipes all previous settings.


Asus support said that code was reserved for "future use"'; however, I've read where different manufacturers use codes within the range F0-FF for their own purposes. Is something to be concerned about I'm still within the RMA period? But to check this out fit a Known Good Power Supply and see if there is any difference.

It could be that one of the Voltage Rails in the PS has either failed or gone out of Spec and is no longer supplying the correct Voltage or enough Current to allow the system to work.

Active Posts. Denied RMA What did you buy today?

I read a bit back in the post about someone having a similar problem with an ASUS P5N motherboard but couldn't find the outcome. It has been a wonderful motherboard. Today, with no warning, while trying to turn on the computer: So, I removed my video card, audio card, memory, and extra case fan.

Still no beeps. Motherboard LED is lit, hard drives are working, dvd drive is working. I assume it's not the PSU. Now, according to you, it's either the motherboard or the CPU.


I have a large heatsink on my CPU, no fan. This allows me to feel the metal on the heatsink right on top of the CPU and it does not get warm when I turn it on. So, this means the CPU is bad, right?
