It's not clear exactly what you can and can't do, but try reinstalling Service Pack 3 by downloading the full SP3 installer from the link below.. It's a large file so you'll need a fast broadband connection to perform the download with. (I would probably use a separate, clean computer, then download the full file, then copy it to a CD. Once that's done, transfer it to the problem machine and run SP3 to reinstall and repair the files that are repairable by the SP3 installer.)
If that doesn't work, then yep, running the Windows repair or format and reinstall everything is probably your best bet because they are both run using the XP bootdisc type of startup.
Hope this helps.
It was sorta my fault, because I don't know much about firewalls, and I didn't know I had to disable it before I unistalled the program. Well, after I unistalled, I rebooted my computer, and it killed my system (I have a Windows XP Service Pack 3).
Apparently a lot of my system files became corrupted. Almost anything directly linked to any Windows files doesn't work. I can't even do a System Restore point, it says "The ordinal 325 could not be located in the dynamic link library SHDOCVW.dll." My local area connection can't link to the internet either. I even lost sound too.
My friend who is a computer whiz says I need to transfer all my files to an external hardrive, then either try to repair my windows files with the Windows system CD my computer came with, or reformat my whole entire drive.
Does anyone know if there is another way to fix this problem? I have to wait a week until I reformat my computer, and it's very frustrating only being able to access the internet at school.
