Neither of these worked, when the computer turns on it will go in F2, Safe mode will not work, F10 only goes back to regular log in, and F12 runs a diagnostic tests. The computer will boot, show the windows screen, show my background picture, and then go to log in screen, when I press log in, it immiedately logs me out. I tried the Dr. WEB live and the avira antivirescue and neither work. The computer will not boot them. I put them in shut the unit off and turned it back on, it will not read the disks. Do you know anything else I can try?
