What do I have to do to make this happen. If I save all my "stuff" (pics, vids, etc.) on and external drive and then totally rebuild my system from scratch to run Windows 7 Pro 64 will I be able to add this drive back into my system?
I guess you didn't understand my question. I have pulled off all my stuff and put it onto another HDD. I want to scrap what's in my computer now except for my 1000w PWS and rebuild it. New motherboard, CPU, memory, OS, etc. The last time I rebuilt my system was in 2006! Will I be able to take the HDD and put into my new system and pull off all my stuff? I don't want to buy a new computer because I hate all the extra crap they add onto it.I've said this before and it never goes down well but this sounds like a bad idea. A 64 bit system needs far more memory than a 32 bit so you'll end up with much the same OS as before but slower and still very much out of date. There are other things I could add like pointing out that you will need to spend a silly amount of time on the project. My suggestion is that you buy a new desktop computer running Windows 10 or at least reconsider your options.
