I'm happy with my new computer, "Thor". is has not locked up once in over 3 months of use ( I'm not counting some programs I use that do lock up, but they're known to do that).
Now I've checked the hard drive for errors and am about ready to re-install my final OS, windows 7 preminum. Yay me.
I think this will be my final OS install after I've read what Microsoft has done with Windows 8.
"Good luck with that"
