Windows XP SP3 Opera 34 and Chrome 47.0.2526.106 BSOD, 0x10000050, PAGE_FAULT_IN_NONPAGED_AREA Found the problem when I found a website that caused a repeatable crash: http://www.techsupportalert.com/ Load page and scroll down crashes before reaching bottom of page. Random since November 30, 2015 found to be a combination of the browser update and Avast anti-virus and Malwarebytes anti-malware. The last version that works OK was Opera 30.0.1835.125 and Chrome 45.0.2454.85. Had problems with Windows 7 x64 but there the browser just closed unexpectedly. Good to have image backups ! I have blocked the auto-update on both browsers. rrrh1(arch1)
