Thanks for the updates. That is precisely the message that I was hoping for from the System File Checker scan!
If you have further issues, please come back and see us here at Bleeping Computer. It is actually amazing how many problems are solved by a cold boot.
Warm booting does not completely clear the computer and reset everything. See this article from Microsoft. You can also "google" warm boots versus cold boots and you will find lots of information there. It is amazing to me how many really weird problems are resolved by a cold boot. It is my first diagnostic step. If you launch the "Windows Repair (All In One)" tool by Tweaking Computer, you will see a cold boot is one of their preliminary diagnostic steps. That tool is available for download here at BC.
With laptops, it also necessary not just to unplug them, but also to remove the battery to ensure that the motherboard loses power, causing components to reset to their default state. Pressing and hold the "Power" button down, when all power sources have been unplugged from the computer/laptop, just hastens, and ensures, that the capacitors on the motherboard, and other boards, such as GPU, drive controllers, etc., also lose any residual power and are reset back to default states. The only thing that doesn't lose power is the BIOS CMOS, because it has its own battery, and removing that is not usually desirable, since the BIOS loses any custom configuration information, as well as the date and time.
On behalf of the Bleeping Computer community, thank you for choosing us to assist you with your computer issues.
Have a great day, ... and stay safe out there in cyberspace.
