Dead PC. 2 problems at the same time.

Hello! First time poster. Long time reader.

So I just finish my first build (like 1 week ago). Everything was smooth. No problems at all (At least I think so).

So today I push my power buttom and... nothing. Just the leds, fans and rgb. But my peripherals were working and a underscore appear.

That underscore appeared since the first time I plug my pc a week ago, but never freezed, like this time. This time it took longer and I did a hard shutdown.

Buuuut now... no signal and no peripherals when I press the on/off. Fans and rgb are on. No Power flickering.

Cleared CMOS... nothing. CMOS battery removal. Nothing. 30 seconds pressing the on/off... nothing. Plug it in another outlet, nothing.

What do you think it could be? I read that some people say that is power shortage... well, my plugs are ok. Could be the PSU, but how I could try to find out that? Some other forums say it could be the CMOS battery (this is my bet because the only problem with my build was that my time never was updated, neither when i force it up... correct me if I am wrong, but a problem in the battery could cause that, no? ).

The other is the mobo... I am 99% sure that the mb has a led indicator that blinks when is turned on (the other 1% is for a misunderstaning of the light coming from another part). Well, in any case, there is no more blinking green light or any other color.

I dont find any post that has the same two problems at the same time: underscore black screen and then no output signal.

Hope all this symptoms help you and me to solve this issue. Thanks!

Can you get into BIOS ? or does your PC not turn on at all, only the RGB lights and Fans?

In order to find out if your PSU is good, you need a PSU tester. I have a tuf plus gaming motherboard, and it had a ram slot problem in which it would not even boot fully (no dipslay output). Possibly move your ram around/try one ram only. ASUS service is pretty good tbh. 

I build computers and networks. Fibre Optic is my only dream imaginable. 

Studying for my CompTIA A+ and my CCNA, if you have any tips, let me know please!

Try stripping everything out except the cpu, one stick of ram, and psu and see if you can get into bios

What Win10 did you try to install?

The recent KB4528760 update for Windows 1909 seems to be causing issues with some computers and stopping them from booting.

Mhmm, I don't know. I have the bootable usb. Can I change that within the files of the usb? I did some windows updates when it first started. No problemas at all, until this.

I had a similar issue where after I updated windows my monitor would turn black as soon as I logged in and I had to completely reinstall windows to fix it. If you just built your computer reinstalling windows completely shouldn't be too painful

But the issue is that I don't even see the TUF gaming logo screen for entering BIOS... hahaha

Get another USB with Win10 1903 or 1809,  try booting from the USB and see, this bug says cannot boot...

Ok so I checked the bootable usb version and if I am not wrong, its build 1903 (annex photo).

 

Also, how Iam suppose to boot my pc if I can't see the bios screen?

This is going to be a dumb question: You are plugging the monitor to the GPU and not the onboard Video ports..? Right?

hahaha no dumb question (its a noob problem), dont worry. I am pluging it to the gpu. Like I said before, first I got a black screen with a underscore blinking for a long time (like 2 minutes), then I hard shutdown and then the pc is dead (no video output, so no underscore, and peripherals are not on).

 

Thanks a lot for your patience and response. I will try different things when I get back from work. I will go buy a CMOS battery to see if that is the problem, as someone in a forum had a similar problem and that solved the issue (the difference between my case and the CMOS solution was that they didn't have first an underscore and then no output video).

 

Another thing is...I found this tread: https://forums.tomshardware.com/threads/no-signal-on-monitor-after-cmos-reset.3254040/

 

I don't hear any beeps from the buzzer, how do I check that?

This b450 MB has a lot of trouble threads on this forum... just search for B450 MB and you should see pages upon pages of issues... you may find some similar to yours too...

Yeah, seems like a different issue you have then

So I just took out everything and plug it outside. Everything is working properly. BUT, for the first time, there were 2 reboots at the same time after getting to a post screen (the megatrends screen). Very weird, tbh. For the record, I forgot to plug the gpu the first time and I turn it on, and nothing happened. I saw my error and hard shutdown, then plug the gpu to power and then the 2 reboots start (for the record: my gpu was pluged in before this when it was in the case, so the only noob error was during the trials outside the case).

 

After the 2 reboots a underscore appear for like 10 seconds and then the american megatrends screen with some text (I annex the photo down below).

 

I went to BIOS and exit, and everything worked well. This time no underscore and it opened windows in a blink of a eye.

 

What do you guys think it is?

 

This guide says it could be a short: https://forums.tomshardware.com/faq/no-post-system-wont-boot-and-no-video-output-troubleshooting-checklist.1575220/

You have a standoff short in the case.. Check to make sure you are using the right screws for the standoff's, you can buy small non conductive washers for the standoff screws to make sure they do not short the MB.

Yeah, I really think is a short. But is very weird, because I didn´t have any problem at all in the whole week I had it mounted. I will buy the washers just for caution.

 

For the record:

 

I put all the screws for mounting the mobo. I was putting 4, now I put like 7 or 8. So every part of the mobo is screwed.

 

Now, I am still getting the blinking line with the black screen for just 2 seconds before getting to the tuf gaming screen where I can go to bios (that´s called post screen, right?).

 

I saw that is a thing with the bootable drive, right? Do I need to be concerned about that blinking line? Or just leave it?

 

I had it on like for 3 hours and no problem.

 

I did some restarts to see if I had problems, but the blinking line only appeared like 2 times (I restarted it like 5-6 times).

 

Now, I saw in other forums that there could be a conflict with the boot order, because I saw in the bios that my boot device is duplicated, one with windows boot manager and the nameof the ssd and the other with just the name of the ssd.
