I can think of a few things, some of them caused by the fact your computer is new:

- Hardware may fail - the early stages of the so-called bathtub curve
- Hardware drivers may be out of date (i.e. installed when the computer was assembled half a year ago, and not updated since)

Take a look at your System and Application Event Logs. In the System log, see if there are any hardware-related error messages. With consumer machines a magnetic hard drive may pause for thermal calibration, I've heard that can last up to 20 seconds, in which case Windows may think a running app is not responding. If you have any disk-related errors they should be investigated thoroughly.

You may see records of crashes of VFP in the Application log. If so see if there are any clues as to why in the details.

Check Device Manager to see if there are any devices that are "unknown" and/or don't have drivers installed. If you find any chase down and install the correct drivers (can often do that with the Update Driver option, a lot of times new or updated certified drivers will be available online directly from Microsoft).

You could also check for a video driver update, especially if there seems to be a video aspect to the problem. Updated video drivers may be available as optional installs in Windows Update.

You could also try running VFP with your antivirus real-time scanning disabled to see if that makes a difference.

Another thing with a new computer is you may have flaky RAM memory right out of the box. Windows 10 has a memory tester you could run. However, in my experience flaky RAM usually causes either blue-screen crashes of Windows itself, or unexpected Windows (not VFP) crashes/restarts, which it sounds like you're not experiencing.
