Windows 10: Why does windows lose signal, and then not boot up at all after?

I recently built a new pc, so after I finished building it, I went over to my friends house and downloaded both windows 10 and windows 11. I then installed it windows 11, but in the process, the monitor lost signal. I restarted the computer and I wasn’t able to boot windows, only bios. I then installed windows 10, just to see if it was a fluke, and it did the same thing. In the middle of the choosing a pin, the monitor lost signal. I’ve receipted my ram, loosened up screws on my m.2 ssd as I heard it this might happen if it is too tight. However nothing has worked. I downloaded windows 11 mult

Monitors Lose Signal On Boot


I have 3 Benq xl2720z monitors all using dp.

In the morning I went to turn on my monitors to find out there was no signal in any of them. I then rebooted my computer and when I got to the spinning orb, my computers faded to black in the middle of it and lost signal. I didn't even get to the login screen.

I then decided to try each monitor by themselves starting with the left monitor. this monitor managed to the login and to the desktop. However it still faded to black as if it was about to lose signal in the middle of the spinning orb. However it managed to recover I guess and show the login. The part that I noticed is that it took much less time to normally to get to the login so something is not right.

I then tried the middle monitor. The first try I got to the desktop just to lose signal a second later. The second try I lost signal during the spinning orb.

For the right monitor, I lost signal when I got to the desktop. Didn't bother trying again with it.

Since the left monitor I could get somewhere I decided to go and plug that one in so I could go and write this, however I accidently plugged in the middle monitor but it was idea I did because something new happened.

I got to the login and desktop fine and it never faded to pure black in the middle of the spinning orb. It showed the whole animation but the second one with the blue screen. It also longer to boot up which was how it was suppose to be.

So I no idea what is going on. It all feels random. Can someone help me with this?

I'm going to try rebooting again and see if the middle monitor is fine now and then I'm going to try all 3 together.

EDIT: Tried again with the middle monitor, it booted without issues. Tried again with 3 monitors, it booted to desktop without going to no signal, however the boot was shorter. Is there a reason for Windows 10 to not go to the seconded spinning orb with the blue screen?

Hi,

No signal issues or screens losing signal may occur due to the following reasons:

• Defective or outdated video cards
• Faulty ports
• Incorrect video setup or settings

Error 0x800700B7 means that there is a system restore error. To further rectify your concern in screens losing its signal, we advise checking and updating your video drivers. Refer to

N70 losing signal

This is really annoying me now. I've had an N70 on TMobile for two weeks and it freezes and loses the signal almost every day. It fails to work in any of the areas where my old Nokia used too. TMobile suggested forcing GSM through the Settings>Network
menu and this fixed it...for one day! Now back to square one with phone losing signal for hours on end wuith no warning, not being able to make or receive calls or text in the middle of a city is a nightmare! Any ideas what to do? Change the phone?
