Can video capture/conversion program affect cable connection

I’ve been converting VHS tapes to disc using the VC500 Video Capture Device and ArcSoft Showbiz software from a company called Diamond Multimedia, running them through my Dell XPS 15 with Windows 10. The system works well, the captures and MP4 files look and work great, but I’m having a recurring problem. After I use the capture or conversion software, my Internet cable connection stalls. It works fine for about 20 minutes, then stops, reboots, runs for 20 minutes again, stops, reboots, etc. This goes on for about 48 hours, then normalizes. The computer also once went into a reboot loop, which again normalized after about 48 hours. I’ve tried closing out all other programs and physically disconnecting the cable while using the programs, then when I’m finished, closing the programs and rebooting the computer, but the same thing happens anyway. The computer also once went into a reboot loop after I used the programs, but again, this normalized after about 48 hours. The Diamond Multimedia tech says that the programs don’t interact with the Internet connection at all, so this shouldn’t be happening, but it happens too consistently for it to be a coincidence.
I’ve checked various help forums and no one else is reporting this problem.
Anyone know what might be causing it? Is there something I can do to avoid the problem?
Am I putting my computer at risk by using these things?

Thanks for any info you can provide

Since the internet should not be required for the app.

Why not turn off the internet for a test run?

Also, video work is very hard work. The machine can heat up and cause issues with other cards. Let's hear your routine maintenance plan. Here's mine.

"On the 1st of every month I used canned air on the vents of my PC."

Thanks-- that helps

The canned air certainly seems worth a try.
As I mentioned in the post, I have tried physically disconnecting the cable while using the programs, but the same thing still happens. I did wonder if the conversion process places such a demand that the computer simply needs a couple of days to normalize. As long as I’m not damaging it, hopefully I can just relax and give it time to catch up.

I usually find it takes one hour for things to cool down.

I haven't seen it take days. If you have never cleaned the vents and heatsinks, do that next.

I will for sure.

Sounds good. Thanks again.
