The machine restarts at random times. I think it may be when it's stressed, though I can't confirm because I wasn't the user it when it suddenly restarts. It's not getting any BSODs. Though, I just had to restore this machine to yesterday because during startup just before the login screen would appear, the screen stayed black indefinitely. Later, checking things, when I saw the failed SFC Scan, I stopped looking further. Now, if there's nothing wrong with Windows files, I should check other items.
There's a Samsung 860 EVO installed with plenty of free space so I'm not looking at the storage since SSDs are pretty reliable. I'll check the RAM and make sure everything's cooling adequately. If you have any other ideas, that would be great!
Thanks,
Tom
