TL;DR Computer installs updates, restarts and then enters unrecoverable system restore, diagnostic software is showing no hardware issues and reinstalling Windows isn't solving the issue.
I built my own computer about 4 years ago and have been constantly tweaking and adding to it since then. The last major update was about 6 months ago when I got a new case, CPU and motherboard.
Since this last update to my computer it has been working fine. Absolutely no issues at all. Then, on Friday, I went to install some Windows updates as scheduled and shut down the computer like I do every night. The next morning the computer goes into system restore because it can't boot into windows. It finds a system restore point and boots up right after.
Thinking that this must have been caused from a bad installation of the updates the night before I foolishly install them again. This time, upon restarting, the computer enters system restore and can now no longer find a restore point. I take this in stride and think that this is a good opportunity to install Windows 10! After using the command prompt in system restore to copy all of my important files off of my Solid State Drive and onto a flash drive I proceed with the installation of the latest build of Windows 10.
Everything is working great in Windows 10, minus a few bugs just from being a new OS. Again, the installation of windows updates and the following restart have brought my computer to its knees in system restore. At this point I'm thinking that there must be an issue with something hardware related.
I take to google in search of some diagnostic utilities and stumble upon Hiren's Boot CD. I install it to my flash drive and get to work. I run a comprehensive health assessment on my SSD, my HDD, my Flash Drive, my RAM and could not find any issues with them.
Thinking this whole thing might have been a fluke I try to install Windows 10 again to find that now my BIOS won't even load the installation media on the USB. The farthest I get it is to the windows splash screen before it reverts back into BIOS to look for a different boot source.
In despair I try and reinstall Windows 7 as a last ditch effort. Miraculously it works and I begin reinstalling drivers, programs, etc. Windows update begins installing the massive 180 some updates to windows before the computer BSOD about 80% of the way through the installation.
I'm at my wits end trying to figure this issue out. I don't mind replacing parts that might be bad, but I don't want to start throwing money at the thing without knowing where the issue is stemming from. I can provide any details you need about my system if it helps.
Thanks for reading through everything and thanks for the help!
