After i restarted by laptop (after 2 months of hibernation), Firefox, Chrome and Outlook stopped working at once. I can see in the process list that there's firefox.exe and chrome.exe, but the applications didn't appear. And my outlook can only work under safe mode. If not safe mode, it hangs each time i enter.
Now I'm in Windows XP safe mode and all the apps above are working.
How can I fix this problem?
