I've had this problem no matter which version of Windows I've used: I have trouble getting into Safe Mode. Some technicians have told me to tap F8 while the computer is starting. The Windows 7 Help says to hold down the F8 key while starting. I need to get into Safe Mode and have been trying both methods - and nothing is working. I think there is a precise time when you have to hold down the F8 key - but I can't find it and need some guidance. Someone please help!!!
