My Dell Dimension 4700 running XP SP3 starts up with no task bar, no start button and none of the .exe files will load. I have not internet access, I can't use ctrl alt delete, and I cannot get anything to load from a disk either. I tried restarting in safe mode, but its just a blank screen that says SAFE MODE in the 4 corners and no other options. I was trying to get it to run the reinstallation CD at start up but the other problem I am having is that the monitor won't turn on until the system is completely started up. So when I hit F12, i cannot see anything on the screen. ANY help would be greatly appreciated.
