The power supply unit may be reaching the end of its lifespan.
After switching the PC on, it stays on for a few seconds and then falls back off again.
But why do old PCs with aged PsU's not stay turned on successfully at try 1 occasionally but then do after a few automated restart attempts?

My File Explorer started hanging again. I've been using Windows since 1994 but have never had problems with Explorer. Windows 10 is an amazing system in this regard. Now I know how to check the system for integrity, how to check the harddrive, how to check it for viruses using several programs.
@Bob I discovered that when File Explorer starts, it does not respond and loads one full core of the CPU. However, if the starting view is not its default folder "quick view" (blue star) but some other folder, it works okay - until I go to "quick view".
Most SSDs use NAND, which retains data without power.
Most SSDs use electronic chips called NAND flash memory. NAND itself is non-volatile, meaning it retains its data even when power is removed, but data loss can occur in a number of different ways that are very different from how an electromec...
I'm kinda surprised that sometimes, my most comprehensive answers don't get that much attention :(
I've written a lot about SSDs and people don't seem to care much about the technical side of flash.
About why trimming matters and why SSDs may slow down when nearly full or when lots of data are written to them in a short period of time.
And how one might extend the life of an SSD that is expected to be used heavily.
I have a number of different answers covering stuff like write amplification, though I don't think I've written much on SLC buffering on the main site...
My recommendation is archival optical media, though unfortunately, we can't really do testing beyond accelerated aging so it's still a bit of a crapshoot. I'd still recommend rewriting the data periodically.
Short answer
It's impossible to guarantee a long timeframe because of entropy (also called death!). Digital data decay and dies, just like any other thing in the universe. But it can be slowed down.
There's currently no fail-proof and scientifically proven way to guarantee 30+ years of cold dat...
It looks like you've hit the 30,000-character answer length limit. If you need to add more information, you can split off some of the content into another answer. Include a link to the other answer in each post to make navigation easier for readers. — bwDracoAug 6 '16 at 20:00
also javaends and it keeps working, headlessly or not... I kind of love that, because it's no longer tethered to a running process other than geckodriver, which keeps running to act as the parent process for the firefox instance
@Bob that's true, but Selenium protocol is inherently sleep-based. It's all based on what's available at a given instant. "Events", for EVERY Selenium-based client and Selenium-based browser host (regardless of the technologies involved) is always poll-based.
"Is it there now? Oh, okay, let's wait a few seconds. How about now?" etc.
there is no support for a browser to send a notification back over the wire protocol that something has happened
It's only a question of whether you need the sleeps in your own code or in a library
Selenide seems to do sleeps really well but for some reason the login process still kinda needs them (not ALL of them, but at least one of them seems to be required)
oh god, this looks absolutely horrendous to write a regex in
I need to test if strings match a regex like this PCRE one: .*(?<![A-Za-z])(T|t)+(?![A-Za-z]).* (or, yanno, .*\\b(T|t)\\b.*) ... Using Lua. Which has no good regex libraries. And I can't do anything native because it's in an ESO addon. And that LPeg library looks stupid
