Windows install dissapeared

[VidgiaGames]

After some split second power outages while I was at school 2 weeks ago, my desktop computer began to act weird. Sometimes when it would boot up from uefi it would show the uefi screen but then just go black and the fans would ramp up. At the same time my windows install became unstable. Yesterday I gathered the courage to face the corruption again and won. I then installed the recent updates and then it was fine. This mourning when I went to power it from sleep it was booting from uefi which was weird, and then it black screened. So I asked my older brother from help since he was home from college. He booted to uefi and noticed that the uefi had returned to default settings. He assumed the black screen was due to boot manager being weird and so restricted it to only booting from my Samsung SSD and then on boot it said it couldn't find an operating system installed. He returned the boot options back to what they were before and it still refused to work, we then tried to force boot to every drive and listed partitian listed but my windows install was not detected on any of them. What should I do?

Hi, I 've lived in a place with fairly frequent power outages and these did cause all sorts of weird problems for my pc at the time, though not as extreme.  Although I'm not nearly as technical as many others, here is what I would do knowing the situation:

-  Swap out SSD, Motherboard and PSU to isolate the problem.

-  It is possible that the computer has been turning itself on which happened on my computer. the reason this happens is unknown to me, but it has something to do with recieving dirty power-This might be causeing your setting resets.  Even if the pc doesn't go through the entire boot sequence, it might be recieving intermittent power when it's shut down.

-  Get a Uninterruptable Power Supply.  This will probably save you from experiencing such problems in the future.  Power outages killed my motherboard once and caused problems that led me to replace my psu aswell. I cannot underscore enough the importance of delivering clean power to your mult thousand dollar pc. Just a few split second power outages can kill your components, get a UPS.
