This computer crashes when launching programs after sitting for an extended period of time.
So far I have figured out that an extended period of time is: longer than 2 hours. This is a "so far" number, in that it may be longer or less to some degree but this is as far as I have been able to deduce to this point.
Not always the same programs. So far, Many programs will not cause it, several programs will, but not every time. Browser (Chrome), Adobe (Photoshop, InDesign, Illustrator), will. Notepad, Word, Adobe Acrobat Pro DC, system programs like opening the recycle bin, task scheduler, etc all seem to be free of causing it.
Programs will "prelaunch". Splash screens come up, the drive is accessed, no crash. It's on actual launch, which for these purposes is considered: when the actual program window is generated after any prelaunch access. This is when it will crash.
The crash is immediate, straight to black (no power), no system event is recorded.
If the machine has been rebooted within at least 30-45 minutes, this crash will not happen no matter what the user does. The user can launch everything they need, go the whole day keeping them open, close them at the end of day and experience no issues.
This machine runs Windows 7 64, contains a Samsung 840 SSD, brand name board and immediate components, is fairly clean software wise (clutter), is protected against viral-malware-ransomware. Graphic machine, meaning the same basic set of programs is run every day.
What I have done. Checked for heat issues, fans, clear heatsinks, seated components and connectors, turned it off and on, checked for software infection. I set up a daily reboot at 7:30 am and the user comes in and launches all programs for the day by 8:15 and we have not had any more crashes, however I can access it in the middle of the night (only because this means it has been sitting) and cause a crash still.
I see it is highly recommended for BSoD to provide a dump file, but this is not a BSoD so I didn't provide one. I am sure I could if you think it's relevant, I wasn't sure.I'm not sure one is even being generated.
