My son has a Toshiba Satellite laptop with Windows Vista. When it turns on you can see the Toshiba logo, and can get into the setup menu by PUSHING F2, but when it tries to boot up, the screen goes black and the cursor disappears. I am not very COMPUTER savy, so any suggestions will be appreciated. Thanks in advance. What is new or different since the last time everything worked properly (ie, new hw, new sw, virus, error, etc)?Nothing new, it did the same thing a couple of days ago, but it finally rebooted. This time nothing....Can you get to SAFE mode (when the system first boots begin tapping the F8 function key until you get to the Advanced Boot Options Screen - then choose safe mode)?After letting it sit for an hour, the screen came up with the how do you WANT to start windows...I started in safe mode and a screen came up with a long list of drivers loading, and it froze on that screenOkay. Sounds like a hardware PROBLEM. I could make a few guesses but laptop hardware is definitely not my area of expertise so let's wait for someone more knowledgeable than I to jump in.Ok thanks...if you know of anyone please send them  my way
