davidm71 Posted October 9, 2016 Share Posted October 9, 2016 Hi, Not sure what is at fault but here goes. Got an Ozmosis xmas bios on my Z87X-UD5h. Was working till upgraded to 11.6. Safe mode works. The gpu is a Gtx 770 from Evga. 14,2 System definition. Haswell 4460 cpu. Monitor either goes to sleep or system restarts back to boot menu. Sometimes see apple logo and sometimes not. Don't even get a progress bar or verbose boot details. Nothing in Console either. Tried with my dsdt and without. Also tried installing nvidia web drivers in safe mode. Nada. Thanks.
