Hi, and thanks for getting back with your W10 version. That's not the full version and build # as per instructions; but that's close enough. There have been about 5 build updates since v1703 came out (April 2017). It could have been one of those. Microsoft puts out weekly "push" updates every Tuesday all year long, and any one of these could be the culprit. If my recommendations do provide a fix (assuming you have not tried them all yet), you should consider disabling your W10 updates in settings. At the very least, reschedule them to occur in the early morning hours. This is helpful because if the updates occur while you are doing something with your computer (such as playing your Game), and a mandatory update reboot occurs while your computer is reading/writing to/from your hard drive, it can scramble your windows. You can search for "Updates" or "W10 Updates" on this forum for my suggestions on how to do this.
Now that you did that, you should know that visiting the HP support website shows that your computer does
NOT have hardware driver-level support for W10. It's quite likely that you did the W7 to W10 update incorrectly, or forgot to run the
W10 COMPATIBILITY TEST when you did so. The good news is that most computers that came with W7 or newer (W8x/W10) should be capable of upgrading to W10 according to Microsoft. The issue is that you might require updating of your hardware in order to do so. This would require BIOS & Chipset updates, which can cause problems if you've never installed those onto a computer yourself before. This is a procedure that we strongly recommend you take your computer to a licensed Tech at a reputable repair shop to do. If not, it's possible that if you attempt this yourself, and make a mistake you could wind up
"borking" your Motherboard (Main circuit board inside your computer). That mistake could cost you several hundreds of dollars as most likely your computer which is going to be 8 years old this year is out of Warranty.
The problem you have is that your manufacturer, HP in this case, has not provided those hardware updates (firmware updates specifically) to their owners or service techs via their support website; no W10 firmware updates.
Did you try any of my other suggestions in my
Post #4 yet? Power-cycled all of your equipment (modem, router, computer)? Backup & System Restore attempted? If you did those already and simply didn't mention it and the problem persists, you should consider taking your computer to a Computer Pro at your local repair shop and pay him to properly update your computer if possible. The solutions I gave you should produce a fix in most cases; however, upgrading an 8-year old computer to W10 can be tricky.

Even if it appeared that your computer was running fine with W10 after the upgrade, that doesn't mean you did it right (or the person you paid to do it if you paid someone to do it or had a friend do it for free).
If this all sounds like too much work or too much money for you, you might just consider replacing that older computer with a new computer that comes pre-loaded from the factory with W10 on it.
Best of luck,
