Question New build booted, crashed and now won't post

[chumad78]

I finished my build with the Asus rog Strix X-670E-E. Things were great; I installed Windows, some other various drivers, etc and all was well. About 2 hours later, my screen went black and things would no longer respond, so I went to power down, and noticed that a long hold on the power button did nothing (suggesting the mobo was non-responsive). I had to kill power at the PSU.

After that, turning it back on would do nothing. I do get power to the mobo because I can see lights on the mobo logo light up, as well as the RGB lights on my RAM. No POST, no Q-LED, no Q codes.

On a whim, I tried to clear the CMOS. I did this by turning off the PSU, then hitting the clear CMOS button on the back. This worked! I was able to bootup and get into windows.

However, it happened again a few hours later and this time nothing I do will get it to come back, including clearing the CMOS.

Any thoughts on what the problem might be?

Try to reset the cmos?

Yes, I did this by turning off the power at the PSU, then pushing the button on the back of the board. It worked the first time; however, now that it has 'crashed' again, that cmos reset is no longer working.

Dumb question but if you reset cmos, pull gpu, pull ram, does the board squawk at you assuming you have a bios speaker. If you can’t get any feedback from the board you may have a dead board or cpu though I might say board.

Where did you purchase from if you don’t mind me asking?

 

[chumad78]

Purchased from Amazon, Newegg and BestBuy.

I don't have a speaker for the mobo. I'll see if I can round something up.

Even if you don't have a speaker just try it maybe and see if it beeps at you or complains. You just want to establish if there are any signs of life from the board/cpu.

You may need to clear CMOS the old fashioned way, but actually it's the best way.

There will be two pins located to the side of your mobo. Typically they are marked as'CLRTC'. Turn off your computer, disconnect power cable, and press the power button a couple of times.
Open up the side panel. Remove the CMOS batter. If you need to remove the GPU, then do that before the battery. Short the two pins with a flathead screwdriver, simply by touching both pins simultaneously. Leave for 30 seconds, and then put the batter back. Close it up and restart. You should be getting a message that says something like ' Please reconfigure your BIOS, and press F1'. It's a slightly different message depending on the brand. COnfigure your bioos as you have done before/ set XMP, and boot her up.

Yes just cutting power won’t clear cmos. Modern boards are better about recovering but clearing cmos as described above is more of an old fashioned way and sometimes necessary.

When I pull everything except the CPU, the motherboard lights up but I don't get any feedback from the QLEDs or the q code. Still don't have the speaker so I can't tell if it's beeping or not.

When I pull the CPU, as expected nothing happens. Board does not light up for anything.

Let's assume I can get the mobo working again by clearing the cmos the old fashioned way... in theory, what could have caused this to happen? I'm running the bios at default settings for the most part -- other than disabling some fan monitoring since I'm using an AIO pump instead of a fan. I suspect if I get it back, it'll just do this again after a few hours. Wondering why...

 

[ohio_buckeye]

Clear the cmos first I would say. Then first thing check for any new bios updates from the manufacturer. I know at work I've seen Dell systems have issues that were fixed by a bios update when you would have thought they weren't going to work properly.

It is possible the board could have just been defective, or possibly a short if a standoff was in the wrong location perhaps? I may be blind but don't see the model of board you have.

If you aren't getting any errors even with no cpu, sounds like the board may have gone to it's final resting place. If it's got the ability to give you status lights etc the board should be complaining about missing all those components.

You may try to do a breadboard where you essentially pull the board from the case, put it on top of the box, and only hook up the cpu, psu and 1 stick of ram. Nothing else. Plug into the video output on the motherboard itself and use a screwdriver, you should be able to attempt to boot the system outside the case that way. If you get a display or it acts like it wants to boot, add 1 piece at a time like that and see if you hit that error. If you don't then double check your case and make sure the standoffs are installed in the proper locations and correctly.

If you do however still have the same thing going on outside the case then you may need to RMA the board for a new one.

From experience, I generally over the years as a a tech have found that if parts work for about 30 days they usually work a good while. Don't ask me why just my experience has been parts typically act up in that first month or so if they are going to have trouble.
