OK - so I picked up this gigantic case on oct 30th (corsair graphite 780 case) along w/ a mobo (asrock z97). The plan was to install the new mobo in the new case and swap out ram/cpu/etc and dump into new case (essentially getting rid of my old mobo. I started all this because i was noticing some instability here and there. And it's been forever since I've done a fresh install, so I figure let's do in 1 shot. Anyway, turns out I'm an idiot and I should have checked what type of socket I had (I thought my old mobo was an 1150 and it turns out it was an 1155). So, after I finish gutting my pc and installing the mobo, I realize that my cpu doesn't fit. So, I decided well fug it. I pull out the new mobo and install the old into the new case and finish the build (so now its all original parts in new case). Side note... as you will soon see, I'm kind of ocd about my pc...
I install the software and it goes quickly enough. I decide load all the windows updates before installing anything else. Well, I learn a few things. 1 - you can't just jump to windows 8.1 - you have to install all of the previous windows updates first. Anyway, I start the updates and somewhere along the line, an update fails in a catastrophic way. It tries to install and then puts the OS into an unrecoverable loop. So, I try a few things, can't figure out a way to sort that, and do another install. I read somewhere that someone hit a similar issue with security patches putting him into a loop and he solved it by installing them manually... well.. there are 100+ updates.
I hold off on that approach and look into slipstreaming. Slipstreaming is a process where you take an ISO of a windows OS and preload it with w/e - in this case, I wanted to preload it with windows 8.1 or at least all of the windows updates. Well, you can't "Legally" slipstream to 8.1 as M$ is apparently retarded about their ISO's now... just for windows 8.1... yeah... and after a bunch of research, I learned that slip streaming windows 8 isn't exactly doable now (you can't download the bulk updates for some reason without MSDN). Super.
Anyway, I try a few more installs and eventually figure out that I'm having a problem with a specific set of patches and I manually install them... whoopie. I then install windows 8.1 from the M$ store. I then try to install updates after window 8.1 and those just fail... not a big deal, but they won't install. Not a big deal if you aren't OCD about your computer. Anyway, I reload all of my software and I'm good to go... except for those few patches. But that said, I'm still seeing a few quirks outside of that (that I had hoped to sort with the reinstall/reseat of CPU).
The next day, I do a bunch of research. New processor, new ram, new SSD acquired. I gut my new case removing all the new stuff (cable mangagement is great, though, so its actually fast to rebuild reinstall (about 1 hour for the entire build). Os installs like a champ and patches up, no issue. windows 8.1 no issue. All patches no issue. Just now finished reloading all of my software/patching things. Think I'm almost square now. End result, stupid amount of hours worked, upgraded, super fast, super stable (fingers crossed) setup.
