I had been running my computer at a stable overclock of 4,5GHz, at 1.2volts. I started having issues a few days ago where I would get an occasional BSOD (WHEA_uncorrectable_error) and from what I gathered it could be the result of to much voltage to the CPU and high temps (my temps were rarely over 50C).
I decided to lower the OC since I don't really need it. I wanted to set it back to the default config and just use the TurboBoost feature to handle any minor OCing. The second I went into the BIOS and changed it back to the default settings and rebooted I got a new BSOD, a INACCESSIBLE_BOOT_DEVICE error. Now I can't get into windows and I have no idea how to fix the issue.
My research says that this error can be caused by changing BIOS settings, but I don't know how to go about fixing this now. Any help you can provide would be much appreciated.
Here are my specs, let me know if you need anything else:
i5-4690K (Corsair H110i GT cooler)
R9 390X
Win 10 Home 64bit
MSI Z97 G45 LGA1150
