Hello. My pc: *Asus Z170-P with 6700K cpu *Corsair 750 RM *Gtx 1080 Ti Founder Edition *Monitor Red Eagle IIyama 24' 1080p 144hz plugged by display port cable to GFX. Few days ago i get power outage. Pc was running in fire strike benchmark. At the same time my mother was powering on electric oven in kitchen. And then power went out in house. Then she go to shop and buy new fuse. Later a friend replaced fuse and power back on in house. When power back. I booted pc first time and all was fine, refresh 144hz . But then i turn off pc . Go rest to bed. After 30 minutes i turn pc on again. And then windows 10 booted with lower refresh than 144hz. To revert 144hz i turn off monitor and turn back on. So conclusion: It happened not just after ( not on pc first power on ) power outage. But on second time ( second turn ) when i boot to Windows 10. On my second turning on pc, second boot to windows. So not immediately after power outage. Just on my second turning ON pc after power outage, it happened. Thats all. And i am not able to reproduce. Turning off pc few times and booting again,and nothing,still 144hz. Even i cut power 3 times to check,but still 144hz on boot. So maybe that was glitch or something but not related to that power outage? My drivers: 388.13 Can i use english? Thank you. I am from England. Danke !!
Well if it only did it once then just call it a day because there's not much you can do at this point
Pc was running in fire strike benchmark with monitor ON. At the same time my mother was powering on electric oven in kitchen. And then power went out in house. Just before power went out, pc was on and monitor was on. When power back ,monitor turns on itself . Then i booted pc , all was looking fine with 144hz. But after moment i normally shutdown pc in Windows 10 and turned off monitor. And on next boot Windows 10 booted with lower than 144hz value. ( on nvidia panel still 144hz ) To restore 144hz i just turned off monitor and turn on again. And this not happened since.
I was thinking about this. Very often when i turn on monitor just before turning on pc. Before Windows 10 logo screen i have NO SIGNAL from monitor cause pc is booting so fast. Maybe this is the reason? <drivers-monitor> . Maybe..
