Hi everyone, thanks for your help in advance. I am not sure what info would be useful so I am trying to include as much info as I can. Please let me know what info you would need to troubleshoot.
Yesterday I installed a bunch of updates and restarted and got a black screen. The CPU powers on like normal, just no interface on the monitor. By black screen, I mean the monitor has power but there is no display. No terminal, nothing.
In the past a few times this happened. it would restart to the bios startup error (“Press F1… Press F2” etc. I would re-order the hard drive then log in just fine). However, a week ago my desktop froze and after I restarted it, it booted straight to a black screen. I eventually resolved that by restarting and booting to a live usb with the same Manjaro Gnome version i was running, which brought up a bios that I then moved the hard drive into the first slot which let me log in. After I restarted again that time, the manjaro screen came up like normal and it was all good.
However, yesterday after installing a screen record program and doing a ton of updates, no matter what I do I cannot get any login, bios or terminal. I have rebooted probably 15 times trying different things to troubleshoot and TWICE (not in a row) I got bios and was able to log in and see my files or see live desktop (so I dont think the problem is the monitor, it clearly works). I didnt want a live desktop the last time so I restarted and its back to black screen again. The problem is, the live usb trick is not even working most of the time. It worked twice out of like 15 reboots.
Not sure if relevant, but I only started getting bios errors after dual booting Windows several months ago so I disconnected windows right away.
My specs:
Manjaro Gnome 21.0.7 on a desktop
Recently replaced power supply (2 mo ago)
Recently replaced CMOS battery (6 mo ago)
Replaced graphics card within last 5 years (cant remember when)
I’ve googled and youtubed and read dozens of articles and nothing has worked.
A short summary of what I’ve tried (nothing made any difference):
-Restart and wait 10-20 mins
-Restart and spam F1, F2, F10, F12 etc. Also tried rebooting and spamming each one at a time per reboot
-Tried getting a terminal by pressing ctrl + alt + F2 (maybe I did this at the wrong time?)
-Tried using a VGA cable
-Made new 64 bit gnome live usb and reboot (that worked temporarily)
-Made new gnome “minimal” live usb and restarted (didnt work) but tried again and got bios
What could the problem be? What should I try next?
