I'm running an old P4 (2004) that has had a Ghost loaded/refreshed on it every 6-12 months. It's never had a problem until now. The pre boot screen (when delete is hit before windows boots up) has the cursor highlighting different parts of the text but flickering between them constantly and very fast. Windows XP will boot but things open without being clicked on, flash all over the screen and close. Anything clicked on opens and closes in a flash and anything the cursor is held over opens before it's clicked on. It's all random. Anyone got any ideas?
