Hey, everyone. My first BSOD occurred about 10 days ago, randomly and frequently. I'd done SFC /scannow and 'Dism /Online /Cleanup-Image /RestoreHealth', nothing wrong. Then several rounds driver verifier, uninstalled some programs with drivers that triggered BSOD, drivers indicated by Bluescreenview or Windbg. Uninstalled Programs like: Softether VPN (selow_x64.sys), Paragon 12 (Wim_vimx64.sys), Pcmaster (pcmastercoredrv.sys). The BSOD chances reduced in normal use, but 100% when launch verifier. A buddy from sysnative form had doubted about the ESET. I thought it's true. Because after rolled back to defender or tried other firewalls, like ZoneAlarm or Comodo, no more BSODs, both normal or under verifier check for days. But I have ESET's two years licence, and had used it for almost 10 years, so I wanted it back badly. After do some research, I found THIS on ESET knowledgebase, quote "On Windows 8 Enterprise 64-bit installation may trigger BSOD if the previous version was not correctly uninstalled". My ESET 7 was installed in Jan, 2013 with previous windows 8 before updated to 8.1. So I figured that I'll need to do manually uninstall ESET. Boot under safe mode followed by this guide “How do I manually uninstall my Windows ESET product”. Also uninstall OpenVpn driver, reference "Constant BSOD with Smart Security 7".【Can't make links yet.】 After this, install latest ESET smart security 8, now I can use normally for days. But with verifier turned on, I've been through BSODs again after booted into windows from about several minutes to hours. There must be something else here in my system, please help me find out what it is. Thanks in advance! BTW: sorry for my bad English. Best regards.
