Steve is having trouble with Google Chrome and Microsoft Edge. After about 2 minutes, both apps crash. Leo says that it could be malware infecting his browsers. But more likely there's a render driver that both browsers use which is causing the crash when he visits certain websites. Leo recommends doing a thorough scan using Windows Defender, and he should also run the Microsoft Malicious Software Removal Tool from the command line. To get to that, he can press the Windows Key and type MRT. Leo also suspects that Java is broken.
At this point, the best thing for Steve to do is backup his data, format his hard drive, and reinstall Windows 10 from a known, good source. It's really the only way to be sure. And it's pretty easy these days. He can run it from the recovery menu.
