To inaugurate: I'm planning a clean Windows 7-64 install.
I'm going to format the drive and reinstall everything from scratch.
Aside from making a list of what I will need to retrieve (Steam, Chrome, etc) and d/l again as well as using my external drive to back everything important up is there any task or tool or just general thing worth remembering that the assembled Agents would recommend?
Having just gone through a similar experience recently that didn't go to smoothly I have to ask a question: Does this reinstall involve ANY sort of hardware changes/updates? If so, check for any possible compatibility issues now. I know that seems obvious but, as I found out, a motherboard that is advertised to support 32 gigs of ram may not actually be able to do that in certain configurations.
Next, put every possible driver you would need on a thumb drive or other external storage. Windows can't retrieve proper drivers without the internet and sometimes generic drivers may not work so you'll want these prepared in advance.
Motherboard chipset drivers
ethernet controller drivers
on board audio drivers (if you are using it)
Graphics card drivers
Sound card drivers (if you use one)
And be prepared for a long haul of Windows updates.
