Operating System not found and CPU fan error

yangster1997 · December 4, 2018

Hello everyone,

So recently I tried to overclock my i5 4690k with my h100i pro cooler on an ASUS maximus vi formula motherboard.

I also have 2 250gb samsung 850 evo running in raid 0

1tb HDD (which was my old first hard drive that i used and just left it in my pc since I had the space)

2tb hdd for storage stuff like movies and documents

I will try my best to list out every step that I took. I first downloaded the drivers from asus's website to update the bios to its latest drivers. Then I got my usb drive converted it to FAT32 format so that I could download the update for my motherboard. I then proceeded to go into the bios and update. After updating I went into the bios again and used the bios's recommended Gamer's OC Profile. Once I restarted and saved all my settings my computer hits me with the CPU error message. I then proceed to go back into the bios and set the cpu fan speed control from 600rpm --> ignore as I have heard this helps the issue and it did. But then all of a sudden I was getting a message saying that my operating system wasn't found. I then tried going into bios again and when I went into the ASUS EZ flash 2 utility and noticed now none of my drives were being recognized in that menu. I then decide to enter into ROG SSD secure erase to see if my SSDs just weren't being recognized and I find both of my SSDs in there but their status's say they're frozen. I then try to reset my launch drive or BBS i think it was called to one of my SSDs and the second option as the other SSD. They both have the same amount of GB so I assumed it recognized that they were running in RAID 0 at least. When my PC launched I was hit the same message saying that there was no operating system found. I then went into bios again and saw an option i didn't see before saying windows boot manager (P1:ST1000DM003-1CH162) which maybe I'm assuming is my old 1tb hdd that I used to use as my main driver back in the day. So I tried doing that and for some reason it worked but the scaling was all out wack like as if I was booting into safe mode. While I logged back in everything that I had on that old HDD booted exactly the way I left it. I then go into windows explorer to see that my SSDs were there and recognized with my other 2tb HDD and all the information was the same in terms of what was in them and stuff like that. (Meaning that the XXX GB used/ XXX GB I had left was the same). So now I have no idea what to do at this point. Please any help would be wonderful. This new PC build has been giving me many headaches lately lol. Also idk how significant this informaiton is but my SSDs in the BBS priorities are labeled as P3 and P5.
