We have a Dell Dimension 4100 that had a hard drive crash. I installed a new hard drive and installed Windows 2000 and then Service Pack 3. I installed to a single NTFS partition. Everything works fine at this point. I installed Office 2000 and the installation went OK. I then try to open any Office program and the program begins starting as normal and then hangs up the entire machine. Ctrl+Alt+Del does not do anything. The machine is locks up. I can turn the power off and reboot and all other programs work fine. If I try to open an Office program the same thing happens again. It makes no difference as to what Office program I try to open. Does anyone have any suggestions?
