I have a toshiba Satellite M45-S331 that hangs at the 'windows is shutting down' screen when I try to use the start/turnoff computer/restart function. The unit works properly when I select shut down instead of restart. I have already re-installed the original files/windows from the toshiba re-install disk that came with the computer. I have checked various websites and have upgraded all of my drivers. Does anyone know what I should check next? Is there a file that may be corrupt? Also, when I plug my USB flash memory (I have two, Sandisk and Lexar) the system hangs. I checked task manager during the hang and the CPU usage is 100%. Are these two issues related? I have also done all of the Microsoft updates.
Thanks for any help,
