I have a Dell Dimension 2400 which hangs at the WIndows splash creen during startup. It hangs during a safe mode startup also, so I am unable to do a system restore. I have tried adding the "/sos" option in the boot.ini file but I see all the messages then it goes back to the splash screen. The computer had been working fine until a few days ago when this started. As I am working on the system for someone else, I am not sure what level of patches have been applied. As stated before, I am even unable to boot to safe mode to find out. Any help iwill be greatly appriciated.
