I configured an old Dell at home to use at work but when I brought it to work it refused to boot properly. I brought it back home and it seems to be working fine. I'm using it to type this now. The only difference is I have it connected to an LCD monitor here and a CRT at work. It did boot into safe mode. I tried to to boot it to VGA mode in the boot menu but that did not fix it. Could it be the display setting? I had it set to 1280x1024. I am not sure if the monitor supports that resolution.
