Freezes on starup (even in BIOS) after CPU Watchdog Violation

I haven't made any recent updates to my system at all. My girlfriend used it the previous week to make a resume and to my knowledge no updates were downloaded. It sat unplugged in the floor for a few days. I plugged it back in and immediate got a CPU_Watchdog_Violation. After doing some research all the fixes appear to require getting into Windows. The only problem is my pc freezes, even on the BIOS screen shortly after startup. I tried unplugged all the hard drives and attempting the trouble shoot one by one and vice versa. And also tried disconnecting all the hard drives just attempting to boot it. It seems with no hard drives connected at all, even then the PC still freezes while on the BIOS utility screen. My next attempt I figure I will try to flash the BIOS with a jump drive. I have reset the CMOS multiple times but I'm not getting much headway on anything.

Any assistance is much appreciated. It completely baffles me because the computer sat unplugged for a few days and worked completely fine the last time anyone touched it. So its extremely frustrating now because I don't even know where to begin. Whenever its good I have a maximum uptime to work of about 2 minutes. And since the BIOS is even freezing with nothing connected I figure a BIOS flash update would be the next in line. Then try to use a recovery media. Again I am completely baffled. Thanks.

I'll make an attempt to do so. Like I said I maybe can get logged into windows and it will operate for maybe 30 seconds to one minute before freezing again. And even with all drives unplugged it will still freeze.

did you try cmos reset .

since system have a onbord video chipset remove gpu from it and plug monitor to internal to see if bios appear .

I managed to do the fix you suggested. But it still froze after I was into windows for a short while. I'll remove the GPU.

 

[joshstone982]

After removing the GPU, I was able to log in to windows an attempted to navigate to asus support page. Then the screen went All-White and the PC was no longer responsive.

do you have a spare cmos battery around for test this way to see if it will keep up and what is the psu you have in this .

I may, is it just a standard watch battery? Or is it specific CMOS battery?

 

[scout_03]

it have to have the same number of the one that is on the board do try any others.

 

[joshstone982]

I found one trying now.

 

[joshstone982]

It still goes to a solid color screen after a while even with the other battery.

 

[scout_03]

does it show current date and time on boot look like you have a board issue or power you did not gave back psu name and model .

 

[joshstone982]

It showing current time and date. PSU is a Raidmax 735W Thunder V2(RX-735AP)

 

[scout_03]

could you borrow another psu for test with minimal parts in system to see if you have bios on and system load and stay .

A while ago I did install an extra ethernet controller just to see if there was any comparison. I noticed the previous week when I plugged it up for my girlfriend to use, the onboard ethernet controler wasn't working. So just swapped it to the other one, no big deal, I'll figure it out later. But the computer seemed to work fine then without freezing when she used it.

 

[scout_03]

so with the eternet card in system work and not with the internal this means board have a issue .

 

[joshstone982]

I think so, I am not 100% certain but I'm like 90% certain, we had a storm a few nights ago and it fried the modem, I'm 90% sure I didn't have the ethernet plugged in at the time. Because when I set it up before I believe I noticed it. But either way I guess I'll throw another $150 at it for a new mother board. Thanks all the help.

if it work with that external nic card kepp it this way and save $$$ for a upgrade later .
