Hi,
I didn't say that you replace Chrome, I only suggested that you try another browser to confirm in the issue is with Windows or Chrome only.
Anyway, your internet speed seems to be fine so the problem might be with Chrome.
Can you try to temporarily disable hardware acceleration in Chrome?
> From the upper-right corner of your Chrome browser, click the three dots icon.
> Select Settings, then System.
> Disable Use hardware acceleration when available.
> Restart Chrome and check if the issue is fixed.
I hope this helps. Feel free to ask back any questions and keep me posted.
