Black Screen Sometimes with Solid Green Light

@ Lordbob:

Thanks for that suggestion. I'll add that to the list of things to try.

At the moment, it seems like disabling the ASUS Gamer OSD program doesn't fix it. I have disabled the nVidia Stereoscopic 3D service in the "services" list and see how that goes.

Thought I'd send a quick update:

I disabled the two nVidia services as well as ASUS Gamer OSD on startup, and the problem still persists.

I should add a correction that the screen goes black after the "log-in + welcome" screen very consistently if it goes bad.

I have now uninstalled ASUS GamerOSD and ASUS Smart Doctor and we will see what happens. Since it happens at such a consistent part of the startup (if it happens...it does not happen all the time), I am feeling like it should be some sort of program/driver that happens at the windows startup. I'll keep this thread posted. Thanks for your help!

The easiest option would be:

1) Replace the monitor

2) Replace the GPU

3) Replace the PSU - I'd do this first.

@ WindowsStarr:

I tried booting it in safe mode a couple of times without issue. Since this occurs randomly though, I will begin doing it a couple times a day just to see. Thanks for the suggestions!

@ FrostMourne:

It is possible that replacing the monitor may fix it. I'll have to dig around to see if I have an older GPU to try out. I highly doubt it's the PSU...it's barely a few months old and that was one item I did not cheap out on.

Again, I'm fairly certain this is a software issue...unless the computer for some reason sends out two different signals at the welcome screen and the regular desktop screen where a damaged LCD monitor can only discern one of them. I would question the fact that that the computer is sending out two different signals.

@ everyone:

Since the last post, I've uninstalled ASUS SmartDoc, ASUS Gamer OSD, and nVidia Stereoscopic 3D (as opposed to disabling it) and also disabled all ASUS programs to start at startup except for the ASUS EPU-6 engine (a power monitoring program that is not straightforward to remove from startup). I think I would have to uninstall ASUS EPU-6 to remove it from startup and am reluctant because it does a nice job controlling the fans etc. If this still does not fix it, I will continue to remove the remaining nVidia non-driver software and then the remaining ASUS programs. I'll keep this thread posted.

Hello, everyone,

I have successfully reproduced the problem when hooking the monitor up to the laptop, though not reliably. Regardless, it seems certain now that it is a problem with the monitor. It was so late in my troubleshooting process because it did not happen until the day after I had hooked it up to a new computer with a new motherboard, new GPU, new PSU and new operating system. I naturally thought that one of those were the issue until the problem worsened enough that I could eliminate all software possibilities.

Thank you for all of your help. I guess now is as good a time as any to experience those spiffy wide screens!
