Hi - formating means wiping clean, and it sure will erase anything corrupt along with everything that is OK. So PLEASE do not forget to back up all you need before formatting, and remember that programs need to be reinstalled after formatting. How about trying a registry clean-up before doing anything drastic? There are a number of programs on the Web that let you do it, some of them for free. Hope this helps - Amos
