I built my computer about 6 months ago and bought windows 7 from my university. It activated fine and has worked well up until a few weeks ago. Windows started to give me warnings that it may not be genuine, my background went black, etc.
I was going to reinstall ("upgrade") windows 7so I first uninstalled service pack 1. After doing this windows no longer gave me these warnings and everything went back to normal. I reinstalled spc 1 just to see what would happen and it started giving me the warnings again.
Does anyone have any idea of what is going on? Should I just upgrade/do a new install? Is it better to do one or the other?
