I'm a new user, and I came here because I have a severe problem with my Dell Dimension 4700 (first problem ever). I'm not that computer savvy, so this problem is extremely difficult for me. I updated Zonealarm last night and when it restarted my computer, I got the message that Windows did not start successfully, and it may be a hardware or software change that cause this problem to occur. It then lists options to start Windows, Safe Mode, SM w/Networking, SM w/ Command Prompt, Last known good Configuration, and Start windows normally; all of which lead to the same Unmountable Boot Volume error page, and I cannot get into Windows at all. I tried using the Recovery Console to fix this problem and then got a different error page, about a Page Fault In Nonpaged Area, and it says that the problem seems to be caused by ntfs.sys Reformatting the Hard drive(if it leads to that) will not be a huge issue for me, because I don't have that many programs that are hard to restore. Any help will be greatly appreciated.
