I recently built a new PC for my wife and we installed Windows 7 premium Home 32 bit. After about a month she got a low disc space warning saying she only had about 1gb left on her 320gb hard drive. After looking at what she had installed on the drive it was nowhere near 320gb...more like 50gb. So not knowing what the problem could be I reformatted the drive and this time I installed the 64bit version of Windows 7. All has been fine for the last three months and then yesterday her computer was running very slow and the message again popped up. This time she only had 300kb of hard drive space that was free. Anyone have any idea what the problem can be? I have a idea but I would like to see what other's think first.
