TLDR: a few weeks ago my computer started turning off signal to the monitors, usually when I was not using it. (On the two occasions where this happened when I WAS using the computer, there was no graphics card crash message). All attempts to troubleshoot the problem have failed. The problem has happened perhaps a total of 15 times over the course of the last month, and seems to be getting worse.
I received this Origin PC for my birthday (see first comment for specs) three years ago and it has been a perfect amazing wondermachine since then (I had a string of rough computers before this and not having to deal with problems has been amazing). Alas that time of perfection has come to an end. I am now cursed to return to my office and find a computer that appears to be on but is sending no signal to the monitors. Unplugging replugging the monitors does not fix it, only hard restarting the computer does anything.
There does not appear to be any software that has to be running for it to happen, but I would guess that I am running innerspace, evernote, and chrome every time it has happened (just because restarting those things are what I do when I turn on the computer). There does NOT appear to be a correlation with taxing the graphics card. It didn't happen at all when I was running 5 wows last month, and only one of the witnessed failures occurred when I was gaming at all.
Changes that may have led to this problem:
- Addition of a third monitor (weeks before problem started)
- Change in a case fan (maybe 10 days before the problem started... potentially I damaged or loosened something else)
- Microsoft Endnote fucking with my machine and trying to force me to log into microsoft rather than a local user (immediately before the first event)
- Unknown Windows 10 or Nvidia driver changes that introduced instability
Attempted fixes:
- Disabled the microsoft login feature (with much swearing and rage as I didn't actually know my microsoft password when this delightful change was sprung upon me)
- Disabled all sleep for all devices (there are a lot of people with laptops whose computers were not "waking up" the monitors when they woke up the computers... this was before I had ever experienced the shut off while using the computer and I assumed it was a sleep or hibernate bug)
- Uninstalled everything nvidia, reinstalled only graphics drivers
- Uninstall Endnote using Powershell (getting desperate now, since I no longer think the problem can be Endnote. I just did this this morning I have yet to see if this will fix it but probably not).
Any ideas what I should try next to troubleshoot this problem? I don't think my keyboard can take much more angry rage banging when it fails to wake up my monitors, the poor thing.
