Built my computer yesterday.

Specs:

Msi Gtx 1080 gaming X
Intel Core i7-8700K Processor

Screens: 144z: Acer GN246HL

I got 2 computer screens, 1 Samsung 60hz and one Acer 144hz. The samsung is connected with a HDMI cable and the Acer is connected with a 144hz DVI cable. Yesterday i plugged in both screens and the computer worked great, everything went smooth. I played games for 6 hours and then turned off the computer. Today when starting it back up, no signal on both screens.

I have tested to only have the Samsung 60hz screen connected with hdmi. I have tested only the 144hz Acer with dvi connected / HDMI. Neither one works. And ive checked that there is nothing wrong with the screen so its the computer. And ive tried using the 60hz by plugging into graphics card, no signal, into motherboard, no signal. Also tried setting each screen to its respective cable but nothing.

I have tried unplugging power cable, holding powerbutton for 30 sec ish and then plugging power cable back in / Holding power button and then after pulling out power cable. / restarted the computer. No signal. Ive also tried using another DVI cable to make sure it isnt the DVI cable.
I have not tried Displayport since the screen im using doesnt have a displayport exit.

The only thing i can think of that might have cause something is that i went into Nvidia Graphic card settings, selected my screen and put it on 144hz. So maybe now when i try to start it up it cant set 144hz or something? But that setting is set onto the graphics card right so i cant change that without a screen / accessing the computer.

PLugging in both / anyone of the screens into old computer they start up instantly and works fine.

I dont know what to do.

I have not, im kinda scared of removing the CMOS, is it just removing it for a minuite (everything is atm unplugged) and then putting it back in? Then should i connect both screens or just one? And is this a permanent solution? Cause removing it means i need to remove my graphics card aswell

Tried it, removed graphics card, removed CMOS battery for 30 seconds, put it back in, put graphics card back in, plugged in power cord and 1 screen, no signal.

Its an MSI Z370 Pro Gaming Carbon / AC
Before the VGA debug light was on but turned off after 15-30 sec.


I get a signal when i remove graphics card and plug HDMI straight into motherboard.
Im on the comp just like yesterday and it works but the grapics card isnt plugged in, what do i need to do / what does this mean?
