I'm using Windows 10. I usually use Chrome, but recently it's been hanging after using it for a bit, from 5 to 30 minutes or so. When it happens, I can't get onto Firefox or Edge either. But I can email, use Google Earth, Calendar, and anything else that doesn't require a browser. I have to reboot to get the browsers going again. I updated all my drivers, and ran the only diagnostics that I've gotten to work on Windows 10 - AdAware and Spybot (can't get MalwareBytes or Microsoft Fix-It to run on Windows 10). The internet troubleshooter says everything is ok. Any ideas?
