Hi i have been using windows 7 x32 for a while now and i keep hitting a major issue. when I turn off my machine some times the installation gets as far as the starting windows sign but the windows logo does not appear, so i cut the power and my computer then comes with a memory error. after i leave my computer off for a while i can load up a Ghost image of my windows installation and it will work fine for a bit. then randomly on some boot up's i will get the same failed boot problem again. any one else found this problem?
