Can't install arch if my second monitor is not connected

Hi, I'm a newbie and having a weird problem: I have been installing arch a lot of times on my laptop and have been working. When I'm in my house I connect a second monitor, and all is just fine. But a week ago I have to disconnect it and everything just failed. The OS crashed, and nothing worked.

This is the weird thing: when try to reinstall it, crash when loading rootfs in ram (when the loading bar appears) then the screen flash and it freeze, and some times show this error:

[Error] cpu pipe underrun a FIFO.

Then, connecting my monitor and it loads fine, I have it on video, I don't know what (the frick) is happening.

On the last good installation I installed some codec packages and modified xorg to change the default resolution of my second screen, but on my installed system. Not on root of liveusb

Adding another weird thing: I had it alongside windows, after all this happened windows crash too. I tried to reset bios but didn't work, it works only when the monitor is connected.

Hope you can help me.

Edit: I wiped the disk, all partitions and all info. Just have it in that state until I can fix it. I'm trying almost everything. But can not make it work.

Edit2: I'm using the lastest iso (12.01.2023) but when I use one from a couple months ago it loads with some errors but the screen keeps flashing and glitching.

Edit3: Memtest86 shows all right

What's your hardware? Try booting with the nomodeset parameter: https://wiki.archlinux.org/title/Kernel … figuration
