I know many people with the X305 model is experiencing similar declines, with the black screen and sound loop, but I have a lot of information I have amassed in recent months. Do not think this problem is related to software, as I formatted my computer several times to install a variety of 32 and 64 bit operating systems from Windows XP to Windows 7 (which currently has 32-bit Windows 7). I made certain I formatted the entire disk each time too. As drivers go, I have attempted almost all drivers for the 9700M is from the newest beta Nvidia drivers, Toshiba drivers accepted, Dox edition driver of (someone recommended using these), and all the way to Omega drivers and the accident still occurs. So what are your thoughts on this?
