When I boot my PC it automatically starts in "Safe Mode." I have been unable to find any documentation to explain how to troubleshoot this problem. In safe mode I have no access to any devices other than the A drive (i.e., no printers, modem, sound, etc.) The pc is an IBM Aptiva Pentium 166 w/16 MB RAM. No hardware changes were made that might have initiated this problem. I would appreciate any help or guidance. Thank you.
