Windows 7: programs stop responding-then respond repeatly I have windows 7 professional. Dell Latitude 5500, hard drive is only 40% full. All programs - including Microsoft Office 2007, Firefox, Windows explorer - stop responding, some times for seconds- other times minutes. This is starting to drive me up a wall. Especially if I am in the middle of burning a CD or DVD. There is no consistency with this. I could go days with no issues, then my computer freezes, starts troubleshooting itself, then fix's the same programs over and over again. any suggestions would be appreciated. I have search the internet. it appears there are post all over the net with this issue occurring..POST but no concrete fixes that i can find. and this issue has been going on for some time.Post dating back to July 2009. Reminds me of the crashes with Windows 95.
