My computer was being a jerk a while back, of course it has to do with the fact it came preinstalled with that garbage Vista!
Got that off, Borged it and was good to go.
Started lagging a bit, it was due for a format so I attempted to give Windows 7 a try, issues, wouldn't install...hate Gateway, 2 days without a computer and I almost forgot how to walk! So re Borged and all is dandy since then.
We are the Borg, resistance is futile!
