Hi,
I have an HP desktop model Y1B39AV I bought in 2017. Yesterday when I tried to use it the display was dark and the PC completely unresponsive, and when I rebooted it just stayed that way (no BIOS screen, Windows screens, nothing) with no disk activity. I verified that the display and cable worked fine on a different PC, checked cables, reseated the display card, tried a few other things, but nothing fixed it. One time only I saw the boot selection screen (boot into Macrium disk recovery or Windows) but the screen went blank after that and I couldn't get it to recur. So I tried replacing the display card which didn't fix the blank screen problem, but it seemed like the startup was working. The disk light flickered, external HDs started up, and if I tapped the power button the PC powered off within a minute, but still the display stayed black throughout. I didn't know what else to do so I was documenting the exact behavior, and all of a sudden it started working and stayed working for the next several hours until I was done. It's been fine since.
I'm concerned that this will recur and I'll have no idea how to fix it. it's not clear if the original display card caused a problem or not, what happened when the machine started working again, if the problem will recur, what to do if it does, or how to prevent it happening again. Any ideas how to proceed? I'd like to feel like I can trust this machine again.
Thanks,
Mike
