Working on a Toshiba, windows 7, 64 bit, home premium. After the type in username and password screen, it logs on normally, loads the desktop (and other junk programs that I will remove when I get access), then all but mouse just freezes solid after about 2 minutes. It also does this in safe mode, when safe mode boots. I cannot boot to safe mode with networking, last known config does not work, but I can get to safe mode with command prompt. The cmd prmt window comes up and is useable, but the safe mode screen behind it is blank with only 'safe mode' in the corners. So, in conclusion, I can boot the pc, but only have about 2 minutes to execute anything. The cmd prompt seems to do okay. I have used a Windows 7 boot cd with no fails on memory diag or no good on start up repair, system restore says no restore points have been created. They did not provide me with any cd's with the laptop. Wondering about fully recovery if fail to find any other options. Knoppix shows a few bad sectors on the drive, but I've seen that many times and not had this issue so bad. It also shows all files resing comfortably when the drive is mounted.
