I have a pc here that has windows 98SE and 512 MB ram. It will boot normally, and with no problems...but when I try to boot to safe mode, I get to the desktop and get a little window that says booted into safe mode. Up to this point, it boots ok then the hard drive light stays on and the pc locks up. I cannot even ctrl-alt-del to reboot. I have to physically restart the pc. I have no issues in my device manager.
