I upgraded my Laptop to have Windows 7 Professional but after some time its taking up too much resources to run half the time and any online videos get skippy and I know it isnt my web browser because I use Chrome for everything. So I put in my Windows 2000 installation disc to try to format and go back to like Windows 7 Home but when it starts up the disc and loads up the files but then it pretty much freezes when it says starting Windows 2000 setup or something of that sort. I don't have the money to upgrade my PC in any sort and this is pretty much my only way to have a smoother "experience".
