Greetings! I have windows XP Home sp3. During Windows update process, power was temporarily lost to the PC. Now I cannot run, uninstall or re-install programs such as Quicktime etc. There is a white square at the top left hand side of the desktop window and many programs in the Start->Programs folder are 'empty'... I'm also unable to re-install windows XP - it says the version installed is newer than the one on the cd. Examining the bios settings revealed that the second hard drive (F was shown as there, but no further details were shown (now fixed) I have very little hair left to pull out - can anyone help with this? Paul.
