Windows 10: Strange problem: Certain sites giving blank page on only 1 computer

On one particular computer, certain sites can't find any pattern just show blank white. doesn't give an error, and the URL gets forwarded to the login URL as if it's working properly, but nothing shows up. happens on Edge & Chrome & Avast browsers. happens in regular window and incognito window. i've cleared cache and cookies specific to those sites.
