Hi, recently installed a 3090 and getting BSOD on certain games, VR titles in particular - as a note it was a 2nd hand card so I already expect that's where the error is, I'd just like to make sure it's nothing else.
On BSOD I'm getting 'Kernel Security Check Failure.' Following the tests here https://forums.tomshardware.com/faq...-error-kernel-security-check-failure.2752277/
There were no failures detected and all core temps seem fine. Annoyingly I took it into a repair store and they couldn't replicate the issue at all and it passed their stress tests. I took it home and within an hour it happened again. Any suggestions to isolate / fix the problem?
